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)

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 are the reasons for the explosion of the cable? In the cable online
- Fiber engineering to see what you are doing, first of all is the cable selection model need to use the number of cable cable. There is a light converter, ODF frame. Open signal will use passive splitter, pigtail, fiber jumpers, optical modules. Brand you have a lot, and you want to domestic or foreign.
- Q: Recently, I purchased two power tools from Craftsman - a 19.2v 1/2drill/driver and a 4.56A angle grinder that look exactly like ones sold by Porter Cable. I don't have links for the drills, but compare pictures of the two grinders below. Other than part of the plastic housing being a different color, you can clearly see that it's the exact same tool.

- Q: I'm running a 3ghz ecs p965t with 2gb of RAM, and I'm trying to install an XFX 8800GT. First time I tried it, it didn't power on at all, and I figured it might be the power supply (mine was a 350w) so I tried a friend's 450w, still no power. So I went out and bought a 500w, and STILL no power. Wierder still, if I leave the card plugged into the board but don't plug in the power connector, it makes a long high-pitched wailing sound but the system does power itself.I'm assuming it must be a problem with the card itself, but does anyone have any other possibilities I could try before negotiating a replacement in PC World?
- I think its the card. This is not uncommon. Card sounds DOA. Exchange it. 500 watts is good, the others are not, but lack of power would not kill a card, I don't believe. good luck. 8800GT is a sweet card, thats what I have, I play at 1920x1080 and get between 40 and 60 FPS in far cry 2 and great frames in oblivion maxed out. I get around 30 in crysis on high.
- Q: Does the ps4 and ps3 have the same power cable?
- Yes it does Adding to that, you need a TV with an hdmi port Also, the power cable doesn#x27;t come with a brick like the Xbox one does
- Q: If I put pressure on the cord I have power but its almost impossable to work. A local computer repair said I have to replace the mother board. Can't the plug in the back be replaced? Thanks!
- Your local PC repair shop must be run by mildly retarded individuals...a loose power cable has nothing to do with your motherboard. You can try getting a new plug...if that doesn't work I might try replacing the power supply... LOL dr.bucksnort....I love it...nice one
- Q: HiI'm organizing my cords at the moment, but I'm curious, is it safe to use power cords (say a phone charger) when it is still wound up in a coil? It would save a lot of cord clutter, but are there any drawbacks, as in it would start a fire? Thanks
- There is no problem coiling the short cords that come with most devices. There isn't enough current to create a lot of heat. But don't leave long extension cords coiled up when you use them. The induction of the coil can limit the power to whatever is plugged into the cord. This can cause the device to overheat and burn out but it usually won't damage the cord.
- Q: I want to turn on my PC but my power cable was missing so i got a new one. A small sheet on the PC's power cable input hole says quot;230 V Rated voltagebut the new power cable fork has some characteristics written on it like EL - 202 / 10-16 / 250 quot;. So I'm afraid that 250 stands for Voltage so the power cable voltage is different from pc's rated voltage. I live in europe and we have 220V here from the power supply.Can I use this power cable or will it mess up my pc ? It's quite a quick issue that I need help with. Many thanks to everyone who can reply quickly. Cheers ;)
- The cable seems to be rated higher than your input voltage so you should be okay.
- Q: i bought a video card off OKorder and i did everything but i don't know if i connect both of the cables to the power supply...i currently only connected one but do i do both…
- I can't tell which ATI card that is, but if you mean that it gave you two 6 pin power connectors or something then yes, you really should plug in both since A) it's not good to give your video card less power than it wants, even if it works regardless and B) if you want to overclock at all then it's necessary. So yes, whatever power connectors are on the card should be plugged in with the corresponding power supply connectors..
- Q: My acer laptop's charger wire thing has broken and i wondered if you knew if you could buy them from shops and how much they'd be?
- They are way cheaper on OKorder. Most are like only $20 give or take.
- Q: (for example : 1sqmm, 4sqmm, 35 sqmm) i need a formula to calculate current by knowing the area of the cable?
- This is not a simple answer. The amount of current that a cable can carry depends on the amount of voltage drop that you can tolerate (mostly an issue in long cables) and the temperature rating of the insulation used on the cable ( the higher the temperature rating, the higher the current that you can run in the cable) and the ability of the cable to loose the heat that is generated from the I^2R drop in the cable. For example, if a cable is in open air with no other heat sources near it, it can accomodate more current before compromising the insulation. If a cable is in a conduit with other cables that are generating heat, then the conductor needs to be increased in size to decrease the heat. The ampacity of the cable is also affected by the duty cycle of the current that the wire is carrying. If the duty cycle of the current is 10% then the wire can carry much more current compared to a current of 100% or continuous. Having said all this, there are tables of ampacities for various sized wires.
