Product Description

SAFETY FEATURES

    Anti-creeping feature of pure Al is weak. During long-term operation, the gaps, which will cause increasing of contact resistance between conductors, will appear due to thermal-cooling cycle. The contact point is easy to generate heat and it is not safety for long-term operation. The problems could be solved effectively through high conductivity alloy conductor.


1, Trend of creepage is largely minimized account for heat and press of material due to special conductor formula and heat treatment technology. Even overheat and overloading happen on cable within long time, it could keep the stability of connection. This has been proved to effective through long-term operation in large amount of labs and in Europe and America Countries.


2, Special arched interlocking armoring structure of interlocking armored cable has excellent feature of dispersing the side pressure. Adopting the 5000 series high-strength Al-alloy metal tape, which is non-magnetic material and does not form eddy current loss. The material has better performances as heat dissipation, anti-corrosion, strong and toughness, flexibility, smooth armoring inside, without damage to insulation, better shield and flame-retardant.


3, Al-loy cable is equipped with various connection and services as copper and Al accessories. It eliminates the electrical and chemical corrosion among connections of different metals. Oxidation of metal surface causes large resistance. It simplifies installation and safe to be used.


Al-alloy cable is light and replaces 50% of equivalent cable. Length of alloy cable is 2 times of copper cable with the same quality. For spanning buildings, it can save 15% steel structure. Smaller loads could improve the safety of the building.


Conductivity Feature

Compare the cable with same specification, conductivity of alloy conductor manufactured by Sinyu company is 62.5% of normal international annealed copper standard (IACS). However, the actual weight of Al is one third of copper with the same volume. According to the calculation, at the premise of meeting requirements of same conductivity, length of alloy cable with the same weight is two times of copper cable. Therefore, the weight of alloy cable is half of copper cable under the same current rating. When the cross section of alloy cable is 1.5 times of copper conductor, the electrical performance is nearly the same. Cable weight could be minimized through alloy cable instead of copper cable. It could reduce the installation cost, minimize abrasion of equipment and cable and it is easy to be installed.

Anti-creepage Feature

  Trend of creepage of metal under heat and pressure is greatly minimized through special alloy formula and heat treatment technology. Stability of Electrical connection by high conductivity alloy conductor is the same as copper conductor.


Thermal Expansion Coefficient

  Thermal expansion coefficient is used to calculate the dimension change of material under temp variation. The thermal expansion coefficient of alloy cable is slightly higher than copper. It has more expansion and shrinkage than copper under change of same temperature.


We recommend using Copper-Al transit connector that connects the high-conductivity alloyed conductor. It has passed 1000 times thermal cycling test specified in GB 9327 (IEC 61238) standard. Reliability of electrical connection is proved. And, it completely solves problems of thermal expansion and copper-Al electrical and chemical corrosion at the connecting point of two kinds of metals by Copper-Al transit connector.


Connection Feature

  The connection feature is largely improved by alloy composition in alloy conductor. That is the basic reason for being approved as ACM conductor material. Iron element enhances the anti-creepage feature. It can guarantee the stability of connection due to long-time overloads and overheat. When the connector, which is subject to 1000 times thermal cycling in GB 9327 standard, it can guarantee long-term stability and reliability of connection. It is not necessary for fastening connection of high conductivity alloy for the reason that it will damage the connection feature.


Mechanical Features

1, Rebound of high-conductivity alloy cable is 40% less than copper cable.


2, Flexibility of high-conductivity alloy cable is 24 more than copper cable.


3, High-conductivity alloy cable has better bending feature and it is easy to be connected.


4, The thermal expansion coefficient of alloy cable is slightly higher than copper. It has more expansion and shrinkage than copper. Therefore, alloy conductor could not be connected by copper connector.



Anti-corrosion

  Anti-corrosion feature of alloy conductor is resulted from thin and tight oxidation layer formed through contact between alloy surface and air. The oxidation layer is resistant to various corrosion. Alloy is expansively applied to cable conductor inside the tray and many industrial components and containers account for resistance to hazard environment. Corrosion is related to connection with various metals under damp environment. Relevant protection measures shall be taken to prevent corrosion. For example, lubricant oil, antioxidant and protection coating can be applied. Insulation or sheath could be applied to buried Al conductor to prevent corrosion. In sulphur environment, such as railway, channel, sewage treatment areas, anti-corrosion feature of alloy is better than copper.

Q:How much is a ps3 HDMI cable and a computer power cord?
It's okorder.com A friend at work suggested I check them out when I was looking for various video and audio cables for my computer and flat screen TV. You'd be surprised how great the prices are. Hope this helps! It seem you've already gotten a ton of great suggestions.
Q:I want to add more Hardrives in my computer but i only have one sata cable how do i add more cables ?
You buy internal SATA cables from a store like Micro Center. You can also buy adapters that plug into your hard drive power supply connectors and then your SATA drives. But you could also buy a new power supply that has multiple SATA power connectors
Q:How should connectors for storage device cables and connectors for power supply be described?
well the storage device cables are called SCSI (Small Computers System Interface) and those power cables don have any special names,,, The power output from smps comprises of four wires.. +12v -12v +5v and -5v
Q:Can I use speaker wire for power cable in a small amp?
It okorder.com/
Q:power cable for laptop broke?
They are way cheaper on OKorder. Most are like only $20 give or take.
Q:The lights in my room goes out when I take out the power cable on my PS3?
Bad wiring in the house? Sounds at least like a situation like that. Not uncommon in buildings of certain times.. older types of wiring used. And worse not ready for todays amount of electronics. So yeah check the wiring. In between time buy a few extension boxes, you know the type with more then 1 electronic socket. But most important a switch. That way you can switch it off and that way such discharges won't happen any more.
Q:I lost my power cable for my Ipod Shuffle 2nd Gen, can I use the 3rd gen shuffle power cord for the 2nd gen?
look and see if the adaptor will fit...if so it should...i doubt they will though
Q:Is there a hdd power cable with a MALE 4-pin connector that extends into one female 4 pin connector and one..?
Probably, but most people just buy Molex to SATA power adapters. If you need more Molex 4 pin plugs, just buy some Y splitters. Any computer store worth a darn should have some of both in stock, even the chain ones.
Q:Need info about transfering data through power cables!?
No it is not possible to transfer the data through power cables, Ask what you actually want to do i will solve your problem.
Q:What is the difference between a shielded cable and a control cable?
I do not know, I do the task, although we also engage in cable
