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: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:Power cable inspection, how many meters should be sampled?
meaning: ZR represents the flame retardant properties YJ said cross-linked polyethylene insulation V said PVC jacket ZR-YJV table red copper core XLPE insulated PVC sheathed power cable 4 * 70 + 1 * 35 said 4 core 70mm2 + 1 core 35mm2
Q:Power Cable Check Well b-type covers show what?
B-grade steel fiber concrete check covers are used for motor vehicle driving, parked urban roads, highways and parking lots C-grade steel fiber concrete check covers for slow lanes, residential quarters and sidewalks D-grade steel fiber concrete inspection covers for green belts and motor vehicles can not travel, parked lanes and venues
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:Whether the interior decoration is the first brush latex paint or the first installation of the wire (the line, with the trunking)?
The 4.0 square wire refers to the air conditioning power cord single copper core cross-sectional area of 4 square millimeters.
Q:The difference between power cable and overhead cable
Insulation structure is not the same, the number of core is not the same. Power cable generally 3-4 phase, overhead cable general core. Power lines can be divided into overhead lines and cable lines. Overhead lines with less investment, easy construction and maintenance, easy maintenance and repair advantages, the disadvantage is the natural conditions (wind, snow, ice, lightning, etc.) have a greater threat to operational safety. In order to save the country's construction funds, the general use of overhead lines is appropriate. However, when the conditions are subject to restrictions (such as overhead lines laid in difficult or special requirements), the use of cable lines. Cable and overhead lines compared to poor heat dissipation, it should be considered in the short-circuit conditions of thermal stability. Therefore, in addition to high-voltage cable cross-section in accordance with the economic current density, allowing voltage loss, long-term allowable current selection, but also according to short-circuit thermal stability conditions for verification.
Q:Power cable casing buried what are the requirements
2 no protective measures, should avoid the termite damage zone, heat source and vulnerable to external damage to the section
Q:What type of cable is the power cable?
Now you have seen what products are not 3c certified? But most of them are fake. Messy on it. Who will check this?
Q:Power cable yjv22-10kv-3 * 50 what it means
10kV XLPE insulated steel tape armored PVC sheathed power cable three core 50mm2
Q:How to find the phone number on the 110 patch panel
Put a piece of paper in the dog's urine, whenever the dog to think about urine when the dog's nose smell, put the paper in the designated place, more training a few dogs will be.
