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:What is the heat of the cross-linked cable?
Video cable refers to the transmission of video signals (VIDEO) cable, can be used as a monitoring system for signal transmission
Q:How to connect the power cable pre-branch connector
In the pre-measured size cut out the jacket and insulation, according to the different cross-sectional size of the cable cut the size of the jacket and insulation different; with C-shaped tube corresponding to the corresponding color sequence crushing the trunk and branch lines, crimping attention to crimping The strength of the clamp, can not be too loose or too tight, too loose will cause the cable crimping off, resulting in open circuit, crimping too tight will break the conductor or cause the conductor stranded in the contact with a good conductor with polytetrafluoroethylene With the winding baking transparent, and then wrapped waterproof tape (tiger belt) can be used after the wooden hammer shrink the cable core to facilitate injection molding in the injection process should choose the appropriate mold and injection molding machine injection mold injection, the mold is too large cost Waste, the mold is too small caused by defective, bad seal at both ends of the running coke, affecting the injection effect
Q:What does ZR-YJV 6mm2 * 3 cable mean?
4S shop is a single-brand car franchise model with "four in one" as the core, including vehicle sales (SALE), spare parts (SPAREPART), after-sales service (SERVICE), information feedback (SURVEY)
Q:Wire yellow and green, respectively, that line of fire or zero line
Insulated piercing clamp is mainly composed of reinforced shell, puncture blade, gasket, waterproof grease, high strength bolts, torque nut and cable terminal cap. When the cable needs to be branched or connected, the cable branch line terminal is inserted into the waterproof terminal Cap sets, to determine the main line branch position, with a socket wrench screw clamp on the torque nut, the process of contact with the blade will pierce the cable insulation, contact with the conductor, the sealing ring ring around the cable puncture position, the shell Grease overflow, when the torque reaches the set value, the nut torque mechanism off, the main line and branch line is connected, and waterproof performance and electrical effects to meet the standard requirements of the parameters. T-shaped terminal is composed of insulation base, wiring frame, fire shield composed of three parts, wiring box by the wire clip, screws, nuts and variable frame and other components, wiring clip and wire contact surface was wrapped in the shape of the dentoid staggered structure, With a large area of ​​spinous process, pressure line reliable features. Through the different shapes of the wire combination of each other, can form a double connection, the lower access to the main line, the upper access to the branch line, the formation of continuous "T" -shaped connection, the product is a protective cover, especially suitable for cable trays and cable And other small places to use, can effectively prevent the suffering of the mouse on the line.
Q:Power Cable Check Well b-type covers show what?
A grade steel fiber concrete inspection covers are used for airports or special roads and venues for expressways that can take off and land for helicopters
Q:Where the computer can be a bare chassis. Which hardware inside the framework
Power cable YJV22-10KV-3 * 400 safe carrying capacity: in the air deposited capacity of 565A, buried 520A.
Q:1omoons / days sensitive quad-core network set-top boxes can be used on old-fashioned televisions.
Network set-top box does not require a computer, only need to follow the operating manual set-top box and TV connection, and then boot the wired / wireless network configuration, with set-top box software can watch the video program. 4M do not see the basic high enough, but now the Chinese network is shared bandwidth, if the use of many people may be cardton
Q:What is the length of the wire that affects voltage and electricity
Can go if you do not trust to wear a pvc into the bridge on it
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:Emergency power off after the computer can not open the machine, an open is a lot of words appear seconds limit, you can
Buried a few is based on the project to be set, as to how much diameter will be based on your plan to determine the cable, the national standard to protect the tube diameter at least 1.5 times the diameter of the cable through the cable. Embedded is to consider the size of long-term power supply, when the load increases, you can directly in the embedded casing to wear cables, so that one-time embedded well, not to re-dig cable cable buried cable, saving time and effort, but also to avoid the Damage to the original cable foundation and the road above the cable
