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: my tv is mounted on the wall, and my friend came round and we tryed to plug in his ps3 and we knocked the main power plug from the tv.we have fiddled about for around an hour looking for wer it came from and need help before my mam gets back!
- Ignoring all the upfront on-line research I undertook, I made 8 separate visits to the showrooms of the 'usual suspects' in UK electrical retail I was so torn between the sony panasonic 42 offerings!! As a brands snob I wanted the Sony because I wanted a sony on my wall.. But every time I viewed the TV's in various store environments I kept getting drawn back to the simplicity if the panasonic's operation, the depth of tone / image on screen vs. the sony. After much consideration I went for the panasonic as (for me) it's a better TV to watch TV on!.. Technically the sony has a faster refresh rate plus slightly more advanced image 'in-fill' technology and technically it should therefore give a
- Q: Hi, just moved to Finland from US. Will my x box 360 works with a new powell cable? Or do I need something else besides that. And where should I get it from in Turku or Helsinki. Thank you!
- Go back to US
- Q: My 4 gauge power cable is hooked up to the battery's positive terminal and the other end to my amplifier's terminal. Is it safe to accidentally touch the ring terminal (end) of this power cable? I won't feel any electrical shock or anything will I?
- if you touch the positive terminal with one hand, and any part of the car's frame or engine block with the other with the engine running at idle, you'll complete an electrical circuit that will put about 13 volts right through your chest. With the engine off, it'll be closer to 12.6 volts. Luckily, your body is a poor conductor, with a resistance of around about 200k to 500k ohms (2 - 5 hundred thousand ohms). Less if you're sweaty. At least, that's my resistance. That means you have about .026 milliamps (13 volts divided by 500k ohms x 1000) of electrical current running through your heart. But don't worry, that's a fraction of what it would take for you to even notice it. Of course, if you have an implanted pacemaker, all bets are off.
- Q: Why medium voltage power cable sometimes write 8.7 / 10kv sometimes written in 8.7 / 15kv where the difference
- . 1.8.7 / 10kV U value of 10KV, which can withstand the maximum voltage of 12KV8.7 / 15kV U value of 15KV, which can withstand the maximum voltage of 17.5KV2.8.7 / 10kV is 10KV system in the first Class II cable (fault time can be greater than 1 minute) 8.7 / 15kV is the first type of cable in the 15KV system (failure time is not more than 1 minute) 3.U0 / UU0 - conductor and insulation shield between the voltage U - the The voltage between the conductors is two, the cable is usually a few or several groups of wires [at least two] stranded from the rope similar to the cable, each group of wires insulated from each other, and often around a central twist The entire outer package has a highly insulated cover.

- Q: this 40gb ps3 has no power computer cord or hdmi cable and i would like to know how much money i would spend all in all with allt he stuff i need...
- no longer all ps3 video games help 1080p, alot are purely 720p. in case your television is an entire hd television (helps 1080p) and it says 1080p on the again of the game case, then it will be in 1080p. If it says 720p on the again of the game case, then it will be in 720p.
- Q: I was playing Call of Duty Black ops when i looked down at my mess of cables. I have a lamp the also plugs into the same power outlet. When i looked down my lamp(that i leave on 10 out of 24 hours of the day) had this white stuff on it. I didn't think too much of it at that time but i looked at it again later and i was nervous that it could be dangerous. Anyone have any idea's as to what it could and if it is dangerous? Will it continue to spread? I don't want my ps3 to be destroyed. I looked on the internet and it sounds like Battery post corrosion. Not sure though. Thank you very much.
- If you have batteries, then it could be these leaking acid, and in time, these will erode your equipment,any other corrosion,I would take as a sign to replace your equipment
- Q: why power cables are to be earthed at both ends?
- Its called the M.E.N. system. It stands for Multiple Earth Neutral. The neutral of an appliance acts as a return, held at a low potential by earthing at each house, using rods into the ground, transformers in the street with earths, and earth mats where required when soils are not conductive. When a fault occurs to earth the low earthing point causes the fuse / breaker to trip. GL
- Q: 3 * 185 + 1 * 95 What is the price of copper cable? Thank you friends help
- That is the two 10KV line is not specifically for you, and perhaps for others.
- Q: im running 4 ga power cable through my 2003 civic and im wondering if anyone hase any good places to run it through?
- I have a 2003 Civic EX and simply created a hole in the boot that has some large cable going through it right below the Glove box. I have no leaks I too have 4 ga size wire. Good luck.
- Q: printer is powered on. cables are securely connected. printer has ink and paper. printer installed as network printer on all client computers. other users are able to print to the printer. but printer not working on the other computer
- go to computer that can print to the printer, click start, click printer and faxes and note share name and ports. then go to printer that does not print, click start, click printer and faxes... if printer is shown, compare with the other computer if printer is not shown, click add printer (wizard pops up) using info from other computer that can print. btw, go to printer manufacturer website, download and install latest software/driver to computer that does not print. good luck!!!
