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:Emergency cable T-box and cable distribution box of the information?
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:What does the cable (YJV-5 * 6) mean?
ZR-YJV22-4 * 16 is ZR armored flame retardant power cable, YJV22 copper core PVC insulated steel tape armored PVC sheathed power cable, 4 * 16 is 4 core 16 (mm2) section.
Q:The wall was sideways opened a trough how to do ah?
The copper core grinding first to the copper core on the flux (rosin or solder paste)
Q:What is the difference between a shielded cable and a control cable?
I do not know, I do the task, although we also engage in cable
Q:1.2 meters below the road can use pvc tube wear armor cable?
The former bv4 square copper wire is a single strand of hard copper wire, the latter BV4 square copper wire is multi-strand soft copper wire. Core (coredwire), with steel sheath for the outer tube filled with iron alloy powder to do core material, cross-section for the circular or rectangular line body. Also known as cored wire. It is used as a steel-making furnace outside the refining of the feed method to add refining agent and alloying agent. Can be directly added to the deep steel, the molten steel for deoxidation, desulfurization, degassing and non-metallic inclusions denatured treatment, to eliminate the aluminum deoxidized steel in the continuous casting steel | iron when the nozzle plugging the problem. As the deep addition of alloying elements in the molten steel, so the alloying element recovery rate is high and stable, the steel components can be fine-tuned to the best range. The reproducibility of the results is good.
Q:The telephone line, TV line, cable, power lines are worn to a wire tube, what will happen?
Friends, only made the specifications, did not inform the specific cable model, the model is not the same price, the following for your reference: the price of the cable in addition to the cable "red price" is basically the same, the general real-time prices at any time with the Cable material prices change, the latest price is the real price, but the cable factory real-time quotations will be some differences
Q:Fourth, what causes the power cable fire accident
After the cable is burned out, the repair time is long and the loss is serious
Q:Brief description of the difference between cable and cable.
Will not interfere with the middle there is no strong electricity! Cable no problem, may be the cable signal as before, you can use a waterproof tape wrapped up ah, do not exposed ah! If the wall with 220V power, then it is easy to string into the TV, the consequences ...
Q:What are the varieties of wire and cable (detailed point)
DJ is a distributed instrument signal cable, also refers to the computer cable, V is PVC. The specific meaning can see the manufacturer's product description.
Q:What is the wiring principle in the home improvement circuit?
Section 4 "Downhole Cable" Article 466 No cable should be laid in the total return airway and the dedicated return airway
