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:The difference between the instrument cable and the low voltage power cable
In this only said home improvement commonly used, the pipe is basically direct, elbow, tee, the price is 5 points / only.
Q:What is the role of patch panels generally, why should the switch connected?
The middle do not have to deal with, but also buried directly, deep 70cm, sand cover brick. It is difficult to repair, but economical and economical land.
Q:Calculation method of wire and cable outer diameter
Usually check the table, in the cable samples or manual check.
Q:Whether high voltage cables can be built in belt corridors
Power cable accessories are divided into several types, commonly used is heat shrink cable accessories, cold shrink cable accessories. (1KV, 10KV, 20KV, 35KV), several models (indoor, outdoor, intermediate connection), each containing the components are not the same, but there are all kinds of cold Heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable sleeve, heat shrinkable tube, sealant and other operating accessories.
Q:How high voltage armored power cable is grounded
Insulated isolation of the double shield control cable is the outermost armor layer should be grounded at both ends, the inner shield one end of the ground, is conducive to the rapid release of induced current.
Q:30 on the large number of cable how to fight on the 110 patch panel, how to order, please inform, thank you, which
I have to integrate a graphics card, you buy a separate graphics card is really a waste of money now I also listed, showing a lot stronger than the 2100 performance, and the market in the low-end discrete graphics upstairs you upstairs a lot of results Even a display did not give people with the price exceeded
Q:What type of cable is the power cable?
Our unit to do the professional cable tray to the current domestic ranking before 3 I did not see we have this certification ah there is a professional health and safety management system has an environmental management system and other quality management system of other scientific and technological innovation patents have a lot of what I do not see the CCC, but you can do the next try you can log in China certification recognized information network - expert column, consult the above experts, these experts have all walks of life experience, can help to you.
Q:What are the lines that need to be set up for notebooks?
Trough is not conducive to heat, tray heat slightly better There is a cooling hole in the bottom of the tray tray Due to open the cooling holes, tray-type bridge plate thickness to thick points ★ problem belongs to the subject: professional information technology engineering water conservancy project the above content is based on the actual work of the students encountered problems, for reference, if any questions please communicate in time, correction
Q:Copper core power cable models which several kinds
They have two kinds of total use, one is the transmission current, one is the transmission signal
Q:With the patch panel how to deal with the line corresponding to the crystal line of the line order is what
The size of the jumper varies with the specifications of the bridge, which is uncertain; the so-called repetitive ground is at least two that is the beginning and end of the end, if the length is enough, the need for intermediate isolation to do the appropriate length of the ground. Stressed that a certain attention to the ground is connected to the power grid on the ground, not directly into the ground.
