Product Description:

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.

Q:Home improvement, the wire specifications generally how to choose? Lighting, sockets, air conditioning with a few square lines? Ground specifications can be lighter than the line of fire, zero line?
You can use, but look at your LCD TV there is no DVI port or HDMI port, the best use of HDMI port or DVI port, the specific look at your TV size, if your TV support 1080P, it is best to use HDMI or D fans ridicule guest Piji nine Depends on the end VI, because the VGA can only 1080I can not 1080P, with HDMI or DVI display will be better.
Q:The wall was sideways opened a trough how to do ah?
PVC pipe. Iron pipe, trunking, bridge, hose, and so on. The The PVC pipe, trunking generally the most common, used in the kind of request is not very strict, not much bit line. Capital is not high, low cost, iron pipe bridge is mainly used in fire strict buildings, shopping malls, high cost, security, line points and more use of bridge hose used in the line out of the floor to the desktop section. Nice point of the ceiling. Overhead floor, are suitable for placement is not comprehensive, personal experience
Q:Calculate the control cable under what circumstances the cable terminal needs to be calculated
You say is the power supply power? Is not the power supply voltage! Power supply is W, that is, tile. Power power is insufficient, it is said that the components will accelerate the aging, aging components are easy to burn, components on the motherboard, of course, is burning the motherboard Oh, and power supply is also easy to cause computer instability. Crash, restart .... and so on. If your power is not enough power, it should be for a larger power and is guaranteed quality power such as Hunt, the Great Wall and so on. General 250-300W power supply on it.
Q:Wire yellow and green, respectively, that line of fire or zero line
4 core 185 square millimeters plus 1 core 95 square millimeters of cable three
Q:Fourth, what causes the power cable fire accident
Once the cable in the event of fire, the fire ferocious, rapid spread, in the burning will occur when a large number of harmful gases, resulting in fighting difficulties
Q:PVC pipe on the GV.215-16 (C) What does it mean
TC line laying is the use of wire steel pipe laying. Wire steel pipe is a thin-walled tube, the nominal diameter is the outer diameter of the pipe. SC line laying is the use of ordinary welded steel pipe laying. Ordinary welded steel pipe is thick-walled tube, nominal diameter is tube diameter.
Q:Dell laptop plug in the power supply usb can not be used, how is it?
Do not recommend you use that, if the time is slightly longer, the battery has lost, and the performance is also reduced. You use the notebook, the battery on the inside, even if the charger has been stuck all right. The computer has a battery automatically charge the chip, say the lithium battery no memory effect, but very lazy. If it has been in the active state will be very lively. Storage capacity will always be maintained, on the contrary, the loss of vitality, your battery is a little bit lost, their own look,
Q:How to determine whether the square of the cable is standard
Depends on your number is not arranged in order, the general building room when the patch panel and the user board number is one to one correspondence
Q:Copper core power cable laying cable sets what fixed
SDH is a synchronous time division multiplexing device, the electrical interface of the 2M signal into the optical interface of the high-speed signal (the use of digital fiber optic patch panel SDHsynchronousdigitalhierarchy) 155M, 622M, 2.G, 10G, etc.). 2 trillion of the signal can be in the DDF above jumper, easy to connect. The optical path signal is spanned on the ODF and is interconnected with the optical interface of the cable or other device. Usually with the network, telephone, etc. are specific business, their communication distance is limited, are generally carried through the transmission network to expand the communication capacity, extending the communication distance. SDH is the main equipment of the current transmission network. DDF and ODF are mainly used in the machine room. The physical interface between devices is BTS-DDF-SDH-DDF-BSC-ODF-MSC or BTS-DDF-SDH-ODF-BSC -ODF-MSC Of course, bsc and msc may also have a section of ODF-SDH-ODF, see the specific circumstances
Q:What is the power cable accessories used to do?
Do not know what you want to ask? What about your situation? Normal or pregnant? Normal this radiation does not affect what, if it is pregnant, this is far away from the best. Pregnancy is most needed to stay away from the microwave!
