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 | ||
1 | PVC insulated PVC sheathed branch cables | FZ-W | FZ-W-3 | FZ-W-4 | FZ-W-5 |

- Q:when i remove the cable it becomes lighter again. what can i do to fix this problem. the os is winXP
- control panel ,power options,adjust your ac settings to full power,readjust your battery power settings,could be a bad power cable
- Q:On my power cable, (the thing that plugs into the wall, and laptop to charge it) well in the middle of the cord, there is a rectangle black box. What is it called, and what is the purpose of it?
- its a transformer to cut the mains plug voltage down to the same voltage as the battery which will be around 16volts to 20 volts for a laptop,the desktop PC will have the same transformer built into the tower casing beside the fan,but you just cannot see it, and there will be a voltage selector switch for the country you are using it in ie-UK =220-240volts, USA=110 volts or similar,both the laptops and desktops use the same internal operating low voltages,and mains voltage would fry everything inside ,that's why they are fitted with the transformers.
- Q:why use of black color for electrical Power cables ?
- Because okorder /
- Q:How to test internet cable through home power plug, stead of internet tester?
- DO NOT DO IT! = Household power is deadly! - At least, household power will fry cables anything connected.
- Q:I have had my Sony Laptop for about 2-3years. And only recently is it acting weird.When I have my power plugged in, the laptop runs fine and can be on as long as the power cable is in. But as soon as I take my power cable out, it automatically shuts down.I checked the power management, and it says my battery has 0% power. I have tried taking the battery out and putting it back in, but it still does not work.The lights on my laptop indicate it is charging, but it does not put any power into my battery and the only way it can run is if my power cable is plugged in. The battery is pretty much dead :/Is there any solutions to this? Considering I bought it in the UK and now live in the US
- your battery is most likely dead and in need of replacement. 2-3 years on a battery is about the life span of a rechargeable battery. you should be able to get a new battery very easily.
- Q:Electric power fittings, cable, tax classification code how to choose
- The incoming and outgoing wires are electrically connected together The potential is the same, which is suitable for tapping or branch wiring It is common practice to add the number of lines back to the number of times The three-branch cable splitter box, which has three equipotential bonding points on each phase, can be used as a second or two-in-one Cable distribution box contains U, V, W three-phase, three-phase circuit structure is the same, along the row together 2 High-level distribution box High-level distribution box containing switching equipment, both from the ordinary distribution box of the tap, branch, but also from the power supply circuit control, conversion and change the mode of operation The switch fence roughly divides the cable circuit into the inlet and outlet sides, and the potential on both sides can be different The switchgear itself has a larger volume, so the high-level distribution box size is relatively large, the height is generally 14 ~ 18m, the depth of about 09 ~ 10m, the length of the number of switching devices according to the number, M to 24 m The shape of the box is similar to that of an outdoor box transformer, and there are a number of active doors on the shell Some doors are designed for the operation of the switchgear Some doors are provided for the installation or maintenance of the cable connection device The
- Q:can you use just one power (positive) cable cut it and use the rest for your negative
- Wire is wire. The only difference is the insulation color. The biggest problem in using wire with the same color insulation is that it's really easy to get them reversed. And just one fraction of a second of reversed polarity and the amp power supply (maybe other things too) is fried. If you insist on using the same color, you should slip a short piece of shrink wrap onto the end of the negative wire close to the terminal so it can be readily identified.
- Q:Two things:1.) Why when we're using an AC to step up the voltage the power has to remain constant?2.) Why is it if we increase the voltage by a factor of 100 we have to decrease the current by a factor of a hundred and therefore I^2R is decreased by a factor of 10,000
- The principle is simple. VI=constant. Energy loss is proportional to I^2. If you want transmit power over a long distance, then V should increase. So the current will be small and energy loss will less. You can not use it because, high voltage gives more shock. When bring it near the home, reduce the voltage so the items becomes less shock giving. Welder use very high current and very low voltage may be 6o volts so that they do not get unnecessary shock.
- Q:should you run RCA cables and power next to each other?
- Keep em seperate or you'll risk engine whinning or other noises. Run the power wire on the left side and signal cables(RCA's) on the right side of the car.
- Q:We found a flat screen HD monitor in someone's trash can and we just need to find the cables. I searched online for cables for this model and can't find any. I just need the power cable for it and the DVI cable.
- try radio shack.
