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: I have an Eclipse SW9102 (101500 Watt Max, 750 W RMS, Dual 4ohm Voice coils) and I'm looking to buy an amp kit and amplifier. How big of an amp do I need and does it matter if its too much power? I'm looking at the SSL F2.2000 FORCE CLASS 2000W amp on OKorder as cost is a big factor in my setup. The OKorder link says:Max Power @ 2 ohm 1000W x 2 RMS Power @ 4 ohm 350W x 2 Bridged Power 2000W x 1 2 ohm stable in stereoIs this too powerful for my subwoofer? I've read that my sub can take more than it says but I don't want to risk it and I probably won't have this at full blast either. If I bought this one how would I wire it as I only have one sub?....would bridged be 4ohm 1000 Watt RMS x1?Also, what kind of amp installation kit should I buy? A lot of the 4 guage kits say they are rated for different maximum wattage. Are they actually different or can all 4 guage kits handle the same?Sorry I'm a noob! Thanks in advance!
- Hey okorder /
- Q: I was walking through the bush recently and I noticed that there were cable towers separated by a valley. How would they get the cable between the towers when there is a cliff on either side?
- From the high point a rope is thrown down. the workers pull this light rope to which a stronger steel wire is attached and then the power carrying wire is attached and pulled carefully over wheels so as not to scar the wire. Lots of sweat and hard work to get it done. and Yes Helicopters are used where they are available.
- Q: So I was trying to run wiring for a 220 outlet and I hit a lower leg with the metal cable snake, now a bunch of outlets loose power for a minute or two ever so often, 20 min give or take. What can be the cause? Only the top breaker tripped. How can this be repaired. Please help.
- You may have loosened a connection. With the breaker off, check all the outlets on the circuit that's losing power and make sure all the connections are tight.
- Q: I've had this laptop (Dell Studio XPS 1640) for about two and a half years, and I've been through three power cables. The first one was a no-brainer, since the end was wearing a lot and you could see the wires. The past two have basically just stopped working for no obvious reason. The blue light on the end of the cord still lights up blue, but my computer says plugged in and not charging. I just bought a brand new one less than four months ago and it's worked perfectly until this past week. Has anyone else been having this problem with similar laptops? And if so, is there anything I can do besides wasting more money on a new cable?
- I would suggest your take your adapter in to your local computer store and they can check it out. If your adapter is working but your still not getting current then the problem is inside your computer and it will need to be sent for repairs... Source(s): CompTIA A+ Computer Professional
- Q: I have a cam camcorder battery charger power cable and I want to use it as a ps1 power cable. Is It possible. The both look the same.
- If your talking about the end that looks like an 8 then yes it should work fine. That is a unerversual power cable. However if your PS1 has a small single round hole, i would be careful. Make sure the power is the same, you can check this by looking on the bottom, it should tell you what the conversion is, for ex: like 120v to 6v. Make sure your not throwing to much poser into your ps1.
- Q: on the end of the cable that connects to the laptop not the power outlet
- It's a ferrite bead, used to filter electrical noise on the cable before it enters your laptop.
- Q: we have one control cable 120 VAC contains 7 conductors and another power cable of 480 VAC each contains 7conductors. can be installed in one conduit
- It is not the best way to do it. There may be some capacitive or inductive coupling between the 480 and 120 circuits that may adversely affect the controls. An accidental short between the 480 and 120 circuits would probably be a disaster for your controls.
- Q: i know i need the sata cable and power cable is that all i need
- IF YOUR CONNECTOR INTERFACE FORMAT IS IDE,THEN YOU CAN BUY A IDE TO SATA ADAPTER CONNECTOR TO INSTALL SATA OR VISA VERSA.
- Q: What is the concept of power cable middle head? What is the difference between a terminal and a terminal?
- Cabling in the integrated wiring system according to the network topology diagram to configure how to connect, no network topology is unable to give the correct connection.
- Q: I have a usb hub that is externally powered that stays on 24/7 even when i shut my computer off. It is buried behind by desk so removing the usb power supply manually each time is what im trying to avoid. Is there anyway i can put a switch in the power cable going to it?
- Before you attempt this, make sure you have the following items: -Wire strippers -Electrical tape -Two terminal switch -Scissors IMPORTANT! make sure that the cable is unplugged from the computer and the hub before you do this! 1st, cut the cord halfway with the scissors. Next, remove the outer wire insulation from the two new ends you just cut with the wire strippers. Now strip the small colored wires that are now exposed. Then connect the red wire from one half of the cord to a terminal on the switch. Do the same with the other red wire from the other half of the cord and connect it to the other terminal on the switch. Strip the other small wires and connect them back to their appropriate colored wire. Finally, wrap each wire individually with electrical tape, then wrap the entire gap in the cord with it. Now plug the cord in and try it out!
