I. Characteristics of the cables
1. Using factory prefabrication methods can substantially reduce the site construction labor intensity and shorten the construction laying time;
2. Use of cables can guarantee great length and bending property, and greatly facilitates the construction in a complex place;
3. Use of cables reduces the laying space, and cables can be installed together with gas and hydraulic gas pipelines;
4. Their reliability and reliability can be fully guaranteed, for the cables are manufactured in the factory,
5. Sub-branch parts should use high strength sealed joints, which are waterproof and have properties of moisture protection, long-term maintenance and free for repair;
6. Because the cables are directly connected with households with no need of maintenance and repair and with easy and simple construction, the cables can produce significant comprehensive economic benefits.
II. Usage of the cables:
1. To be used for high-rise building;
2. To be used for disaster prevention equipments;
3. To be used for tunnel lighting and disaster prevention equipments;
4. To replace copper bus bar with small or medium capacity in various places.
III. Standards of the cables
IEC 60502 Rated Voltage 1 ~ 30KV extruded insulated power cables and accessories (International Electrotechnical Commission standards)
GB 12706 Rated voltage 35KV and below Copper core, Aluminum core plastic insulated power cable (National Standard of the People's Republic of China)
JCS 376 branch cable (Japanese Electric Wire Industry Standard)
General Rules for JIS C2810 indoor wiring electrical connection pipes (Japanese Industrial Standard)
Types of the cables:：
Standard main cables and branch cables are all low-voltage power cables with XLPE or PVC insulation materials (IEC, GB, JIS, BS ... ...), and PVC materials covered on the outer side. Generally, the main cable is single-core or twisted multi-core cable (cables with two to five cores), the branch cables are single-core cables, and may adopt a fire-resistant, flame retardant cables in accordance with the requirements.
Their structures and types are as follows:
No. | Cable Description | Type | |||
single core | three cores twisted type | four cores twisted type | five cores twisted type | ||

- Q:what is the resistance of overhead power cables?
- electrical resistance? depends on length, temperature end diameter mechanical...depends on material, steel, copper, aluminium... resistance to corrosion, to fatigue due to vibration from the wind... be more specific Guru
- Q:On an ATI Radeon HD 4870 1 GB, It has 2 slots of PCIe Power. In the box, it already has the 2 ''Y'' cables/PCIe Adapter ( I haven't bought it, just watched someone unboxing it). I might not have a PCIe Power Connector on my 550W as I haven't bought it yet either. So when you insert the 2 ''Y'' cables/PCIe Adapter,it branches out 4 Molex slots, do you insert all 4 or 3 or 2 or just 1? If the answer is 2, do you insert one Molex connector on each adapter or both on the ''Y'' Cable/PCIe Adapter?Lastly, Can a ATI Radeon HD4870 fit into a micro-atx casing?Sorry for my bad EnglishThank You =D
- The card needs 2x PCIe power cables so you need to plug in both of them. Each power cable needs 2x molex, so you need to plug all 4 in. Your power supply may also have a PCIe connector anyway so you might as well use that for one of them if you have it (it can't be used for anything else anyway) and then just use 2x molex to power the other one.
- Q:Wire and cable manufacturing process (to be detailed)?
- Copper core per square of the safe current (continuous use) for the 2.5A, intermittent use of 4A, according to the power count 550W-880W.
- Q:I'm gonna be running a 2,700watts RMS system on a Power Acoustik 4,500watt Class D Monoblock amp at 1-ohm. I have a 2005 Impala LS do I'm going to need a secondary battery. What size should it be? Also what size power wire and ground wire should I use? I'm going to be using 8gauge speaker wire. Any help is appreciated. Thanks!

- Q:My power cable says it is plug in but will not charge it. What is wrong?
- It could be your cable or power supply unit went bad. Or, your power socket on the main board went south. The good thing about laptops is that the power supply unit is external and easy to swap out.
- Q:I recently bought a new internal hard drive for my computer (Hitachi Hds721010cla332, a upgraded version of what I currently have). When trying to install it I found out that the power socket isnt the same as my current hard drive. Ive been searching on the internet but cant find an adapter that converts from my current hard drives power cable to the new hard drives required power cable.

- Q:Hi, I bought a geforce gtx 660 ti and with it came 2 X 6 pin PCI express power cables. Problem is I only have 2 connectors in my computer, so one cable is useless. Will 2 Athena Power Model CABLE-YPHD 8Molex Y Splitted Power Cables allow me to use both the PCI cables? Thanks.
- Hi There, Both ports need to be connected for power for the card and if that is the case then two feeds from the power supply would need to be used. This would be because one power feed with the Y connector probably would have too much load on the one single feed and it would overheat and could cause a big problem. To be absolutely sure you should refer to the instruction manual for exactly what is needed. If still unsure a call to the manufacturer should sort things out. By the way this video card requires a 450 watt (or larger) power supply to operate properly. I would buy a proper power supply for this powerfull video card. This card needs 400 watts if overclocked so I would go for a power supply of about 600 watts (or larger) with feeds for each power adapter for the video card. Hope this helps, Al
- Q:im hooking up a system in my truck..im doing it the redneck way they way i have watched my dad do it many of many of times. im using jumper cable wire!! yes jumper cable wire, its plenty of juice the perfect size! but im not sure if he ever used a fuse link.do you have too? what if i dont use one? if so where is the cheapest place to get it?what size fuse is it?
- Jumper cable wire, in fact any wire of the appropriate AWG (or bigger), is perfectly adequate as far as the current carrying capacity is concerned. One problem with using such wire is that the individual strands are much thicker resulting in the overall cable being much stiffer and harder to pull and bend into place for a typical installation. You really need a fuse. It's purpose is to protect the vehicle electrical system (and the vehicle itself) if there is a short in the connected equipment or wiring. Most auto parts stores will have fuse holders and fuses. Likewise car audio shops. Even WalMart. The main fuse size is usually specified by the manufacturer. If not, look on the amp itself. For example, the Pioneer GM-D8500M Class D monoblock amp has a pair of 30A onboard fuses. In this case your main fuse should be at least 60A. If the 60A fuse blows under normal operation, you would then go up 1 size to an 80A. This allows the amp to draw sufficient current, yet protects the vehicle in case of a short.
- Q:I have recently decided to scrap my capacitor and need and extra two feet of power cable in order for it to reach the amp....is it possible to splice and join two power cables together or is it a better idea to rewire with a longer cord?
- The only way to properly splice the cable is to solder the cable to another piece of cable the same size. The best insulator is brush on tape , just make sure whatever you choose to use, it is sufficiently wrapped. There should minimal power loss if care is taken to make the connection well. However, the best way would be to run a new cable. But considering the trouble this may pose, a quality spice may be the best choice.
- Q:Hi! I want to buy I new Hard Drive but I've got a problem. I have the IDE conector but I don't have the Power Cable. It is connected to my Video Card. Can I add a new one? Can I use a power cable from a optical drive(CD/DVD)? Thanks!
- All you need to do is pop down to your local computer store and get a power splitter, just make sure you get the right type, IDE and SATA drives have a different kind of power connector, so just make 100% sure before you buy!
