Significantly reduce installation time with Belden’s Copper-Fiber Hybrid Cables, which require only one cable to safely transmit data and power across long distances for applications such as passive optical networks (PON) and distributed antenna systems (DAS). The cables are ideal for remote locations where standard power is unavailable or too costly – and Power over Ethernet (PoE) is unable to reach. In addition to indoor and indoor/outdoor breakout (3 mm), distribution cables (plenum and riser-rated) and AIA (aluminum interlocked armor), the line now includes indoor distribution riser cable and indoor/outdoor distribution riser cable.
Deliver power to applications that PoE and remote DC powering can’t support due to distance limitations. To achieve even higher power levels over longer distances, 14 AWG Digital Electricity Cable is now available to carry 2,000W of DE power up to 750 ft or 100W up to 6,000 ft. Other product line additions include Digital Electricity Cables with a UL Listing, an LSZH option and wet location ratings for indoor/outdoor cables. For better protection against water in below-grade, in-conduit applications, a water-blocking tape is also available.
Belden’s FiberExpress ECX Pigtail Splice Cassettes are now available in preloaded six- and 12-port LC Duplex configurations. They include pre-routed 250 µm color-coded pigtails for individual fiber splicing or can be ribbonized for mass fusion splicing. The splice cassettes also include a splice holder and splice protectors for individual fiber splicing. ECX Pigtail Splice Cassettes support greater bandwidth needs and allow for increased fiber deployment inside and between buildings.
BU Multimedia Solutions (MMS) of Prysmian Group has upgraded its portfolio of Draka single-mode fibre optic cables with higher bending performance. With the upgrade of G.652.D fibre to G.657.A1 fibre, customers will benefit from higher bend insensitivity of their installed fibre optic network cables. Draka G.657.A1 fibres offer the highest reliability and performance, as well as low bending losses – even in critical situations. They allow tight installation radii and are fully compatible with G.652.D fibres. The cables are offered at the same price.
The ever-increasing data traffic requires an exploding demand for transmission capacity and network infrastructure. Last but not least, new technologies such as 5G, Internet of Things (IoT) and artificial intelligence support this trend. Optical networks must adapt to these requirements as quickly as possible by increasing their dynamics, offering higher capacities and lower latency. At the same time, density is increasing and optical networks are reaching their limits in terms of space.
“All of this sees fibre bends are becoming more and more likely to occur. Preventing power leakage due to bending effects is, therefore, an increasingly important part of the necessary transition to flexible and reliable fibre optic connectivity,” says Gerard Pera, Product Manager Optical Data Cable of MMS, Prysmian Group. MMS is responding to the new requirements by upgrading Draka’s single-mode fibre optic cables from G.652.D fibre to G.657.A1. Gerard Pera: “Our new fibre optic cables are much less sensitive to bending without causing high losses. This applies to installation in floor, door and window strips as well as in racks where the cables are heavily bent due to lack of space”.

Water plays an essential part in the cable manufacturing process as it helps cool down the jacket moulded around the cable or wire. But moisture is also one of the main issues encountered during manufacture as it can have a significant impact on production cost and efficiency.
Whether it be at the sheathing phase, spark test stages, the mid-production measurement or final inspection, no moisture must remain on the cables or wires. Sound insulation is vital to ensure the highest quality, functionality and safety of cables.
So why is residual moisture such an issue for cable manufacture – and how can this problem be overcome?
The purpose of a cable jacket or sheath is to protect the inner cable and wire from moisture, mechanical and chemical damages. A cable may remain wet due to the previous operation, or poor storage conditions. Whatever the reason, if moisture is present on the cable or wire when entering the extruder, the insulation or jacket may not form properly, leading to swellings within the extrusion and holes in the jackets. If this occurs, it affects the quality of the product, so the whole production batch must be replaced.
JACKET THICKNESS MEASUREMENT
The cable jackets are measured in mid-process to ensure they meet the required specifications. Following the first cooling bath, the jacket diameter is measured so the extruder feed can be adjusted if the jacket is too thick or too thin. The cable/wire needs to be dry to ensure that the electronic measurement equipment doesn’t pick up water droplets as anomalies within the jacket. When the system records variances, it stops the manufacturing process thus affecting productivity.
FINAL INSPECTION MEASUREMENT
Following the final cooling operation, the cable jacket is rechecked to gauge its concentricity and diameter dimensions. If moisture is present on the wire during the measurement, the system records it as anomalies within the jacket resulting in quality test failures.
During the manufacturing process and subsequent phases of production, spark tests are carried out to check the insulation of electrical conductors. The cables pass through the spark test equipment which detects any pinholes or fault within the insulation. If too much moisture enters the spark tester, it sets the unit off, giving a false error.
Wire and cables must be adequately dried before inspections so that any issues highlighted are real errors that require inspection/investigation. By using ACI cable drying systems, you ensure quality control and process optimization in your extrusion lines. In other words, you can be safe in the knowledge that it is a production issue and not due to water contamination.
In order to supply modern motors with energy and data, users need appropriate cables that function reliably, even at high accelerations and on long travels. Especially for dynamic use, igus has now developed a hybrid cable that is offered as a drive solution for the new Bosch Rexroth motors. It combines an energy and data cable in one and is therefore also ideal for compact installation spaces. igus also offers the cable as a fully harnessed readycable.
The trend to have smaller and more compact machinery with an even higher output is becoming increasingly apparent in the field of motor development. Not only the motor, but also the cables used, must meet these new requirements. Hybrid cables are one solution as they combine energy and data supply in one, by integrating the encoder cable into the servo cable. This eliminates the need for cabling with a separate measuring system for the encoder. Designed specifically for use in energy chains, igus has now developed a new hybrid cable suitable for Bosch Rexroth MS2N and IndraDrive Mi motors. A halogen-free PUR outer jacket ensures oil resistance and increases the service life of the cable. The user receives the drive solution already fully harnessed with connector, this is known as an igus readycable. “While other manufacturers on the market only offer cables in metre lengths, customers can order their solutions from us down to the centimetre. This way we avoid unnecessary waste or residual stock. As readycables, the cable can be connected directly to the machine. This saves additional harnessing and installation time”, explains James Harrison, readycable Product Manager at igus UK.
readycable finder helps in product selection
All cables are tested and inspected under real conditions in the company’s own 3,800 square metre test laboratory. Tests have shown that the new hybrid cable with a bend radius of up to 10xd in the e-chain can safely withstand 10 million double strokes over the long term. Due to the realistic tests, igus is the only cable manufacturer in the world capable of providing a 36-month guarantee on its chainflex cables. In total, igus has over 4,200 drive cables suitable for 24 manufacturer standards in its readycable range. For a quick selection of the suitable solution, with the readycable product finder igus offers a practical online tool. Simply enter the igus part number, the manufacturer or select the name of the drive manufacturer from the menu; then click on the required cable type and the product finder will list all matching parts. An overview provides the different cable qualities such as outer jacket, bend radius, travel and price. The integrated service life calculator also determines the running time. One click is all it takes to order the matching cable in the desired length and have it shipped within 24 hours.
[2020-07-16]Solar Plant will help reduce 660 tonnes CO2 annually, inaugurated by HE Saeed Al Tayer, MD and CEO of DEWA
Ducab Group, one of the UAE’s largest manufacturing businesses, has taken a significant step towards increasing its sustainability with the official opening of its Solar Plant, which was inaugurated by His Excellency Saeed Mohammed Al Tayer, MD and CEO of Dubai Electricity and Water Authority (DEWA), in the presence of Dr Ahmad bin Hassan Al Shaikh, Chairman, Ducab, Board members and senior officials from both parties.
The Solar Plant, a 2MWp (megawatt peak) Renewable Generation Project located at Ducab’s head office site in Jebel Ai, Dubai, was developed in partnership with Etihad Energy Service Company (Etihad ESCO), in alignment with the UAE’s ambitions to harness the potential of solar power. Comprising of both rooftop and ground mounted solar PV, the combined plant has a capacity to produce 3.5GWH (gigawatt hours) annually, which is enough to meet the energy needs of 500 homes, or sufficient enough to run the Ducab PVC plant on site.
Energy generated by Ducab’s Solar Plant will lead to savings of approximately 660 tonnes per year of carbon dioxide – equivalent to the quantity of carbon dioxide processed by 40,000 trees over 10 years.
HE Saeed Al Tayer said, “I am pleased to commission Ducab’s photovoltaic solar plant. I congratulate the Group on this achievement, which affirms its commitment to a culture of sustainability. It also underlines Ducab’s role as a leading organisation that supports the vision of our wise leadership to reduce carbon emissions, and the Dubai Clean Energy Strategy 2050 to make Dubai the city with the lowest carbon footprint in the world and provide 75% of Dubai’s total power output from clean energy sources by 2050. This project also supports DEWA’s efforts to protect the environment and preserve natural resources by increasing the share of renewable and clean energy in Dubai’s energy mix. DEWA also encourages individuals and organisations to install solar photovoltaic solar systems in buildings as part of the Shams Dubai initiative, which supports the Smart Dubai initiative to make Dubai the smartest and happiest city in the world.”Dr Ahmad Al Shaikh said: “Ducab Solar Plant represents our continued efforts towards making our business more sustainable, in line with the vision of the UAE’s leadership and our own commitment towards the environment. We would like to thank His Excellency Saeed Al Tayer, DEWA, and Etihad ESCO for their partnership in making this project a reality, which will lead to considerable emissions savings, as well as valuable financial savings.”
Designed to last the 25 years design life, over 150kms of Ducab’s specialist UL certified SolarBICC range of wires have been supplied for the Solar Plant, that also includes 300 sq.mm low voltage copper cables which have been an integral part of this power plant construction. From Design approvals, to Testing and Inspection right upto Energization for both rooftop and ground mounted PV plant, DEWA’s guidance and invaluable support has been testament of a true partnership. The project utilises the latest smart technology applications including DEWA Smart Metering, remote monitoring of power output using a web or mobile app, and automated self-cleaning solar panels using solar-powered cleaning robots.
The new measures which make sprinkler systems mandatory in all new high-rise blocks over 11 metres high are so important they will help save lives and property in the event of fire, says specialist AEI Cables.
Stuart Dover, General Manager of AEI Cables, said: “The new guidance is so critical that it will undoubtedly save lives and property at some stage but we need to see the detail behind it.
“The fire performance industry has been waiting for this announcement for some time so it is warmly welcomed, but now we need to see how it will work in practice.
“The sooner the practical guidance can be rolled out then the sooner they can be applied and the sprinkler systems being specified now can be installed in the knowledge that all best practice has been followed the interests of safety for all concerned.”
The government announced an amendment to the statutory guidance to building safety regulations, known as Approved Document B, reducing the requirement for sprinkler systems from the current 30 metres to 11 metres.
The Fire Safety Bill, which was introduced to Parliament in April, will also empower fire and rescue services to take enforcement action and hold building owners to account if they do not comply with the law.
The tried and tested generation of AEI Cables’ fire performance cabling ensure critical fire-safety circuits can continue to operate in the event of a fire from 30 minutes up to 120 minutes and often support systems which provide intelligence for the fire and rescue services.
AEI Cables’ Firetec Enhanced cabling is the only cable to be independently approved and certified by LPCB to BS8519 (Annex B) Category 3 Control for firefighting systems including sprinkler pumps, fire suppression water mist systems, water spray systems, wet riser pumps, wet riser valve and equipment monitoring under the Code of Practice.
【2020-6-2】Apple plans to invest USD 330 million to build a factory in Taiwan, China. The development of the Micro LED display will become a "top priority". The new Taiwan factory will produce LED and MicroLED displays for future iPhones, iPads, MacBooks and other devices Screen. According to Taiwan Procurement Service Provider (CENS), Apple's partners are expected to be LED manufacturer Epistar and LCD panel manufacturer AU Optronics.
The new plant will be located at the Longtan branch of the Hsinchu Science Park. Apple’s total investment is expected to be NT$10 billion (approximately US$334 million). The new factory will be an expansion of Apple’s business in the region. It is said that the company has sent a development team to Taiwan for project development. For a long time, Apple has always expected to use Mini-LED and Micro LED in a series of products, including the current Apple Watch in 2020 and the new models of the current 16-inch MacBook Pro.
The report highlights the advantages of Mini-LED and Micro LED screens over LCD and OLED displays, including thinner and more energy-efficient. For example, the power consumption of a MicroLED screen is only one-tenth that of an LCD display, and the color saturation is close to that of OLED.
Like OLED, Micro LED is self-luminous. However, compared with OLED, Micro-LED can support higher brightness, higher dynamic range, wider color gamut, and also achieve faster update speed, wider viewing angle, lower power Consumption, these are the qualities that Apple hopes to achieve. However, due to the difficulty of developing Micro LED technology , early design will rely on the Mini-LED between traditional LED and MicroLED technology. Nevertheless, Apple still regards MicroLED technology as a "top priority."
Analysts said that Apple has six Mini- LED products under development, which are expected to debut in 2020 and 2021. It is reported that Apple will launch the high-end 12.9-inch iPad Pro, 27-inch iMac Pro, 14.1-inch MacBook Pro, 16-inch MacBook Pro, 10.2-inch iPad, and 7.9-inch iPad in the fall. The technology debuted in mini.
Except for the iMac Pro and 7.9-inch iPad mini that are expected to be launched in the fourth quarter of 2020, the launch dates of other devices are not mentioned. There is also news that Apple will launch a 7.9-inch iPad mini in 2020.
According to reports, Apple began testing prototype Apple Watch models equipped with MicroLED displays in 2017. Although there are rumors that the Apple Watch with MicroLED display may be launched as early as 2020, Twitter leaker @L0vetodream poured a pot of cold water on this prediction on Sunday, saying that this year’s Apple Watch Series 6 will be used with The previous models have the same OLED display.
Mini LED is quickly becoming a high-frequency hot word, from upstream LED chip manufacturers, to downstream LED packaging manufacturers, to system manufacturers such as display screens on the application side, and to terminal electronic consumer products manufacturers of TV computers, all talking about Mini LED , Even rubbing hands, investing a lot of capital and other resources to do a lot of w
