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 does the cable (YJV-5 * 6) mean?
Full name: cable ZR-YJV22-4 * 16MM2ZR: flame retardant ----- YJV22: copper conductor cross-linked polyethylene insulated PVC sheathed double steel belt wrapped armored power cable --- 4 * 16MM2: 4 core, each core 16 square millimeters.
Q:What is the difference between VV22 and VV62?
The conductor of the cable is resistive, and the current when the cable is running through the conductor to heat up. In a certain installation, ambient temperature conditions, the heat generated by the conductor current and cable in the operating environment under the conditions of the heat dissipation is equal, when the current is safe operating current, which is commonly referred to as the cable carrying capacity. Cable carrying capacity is in a certain installation, ambient temperature conditions, the load, so the installation, the ambient temperature conditions are different, carrying capacity is different from the ambient temperature changes, the safe current is also to change. Therefore, if the cable is running at a certain installation and ambient temperature, if the actual carrying capacity of the cable exceeds the safe cut-off, the heat generated by the conductor is greater than the heat of the distribution, the cable will heat up; the same time when the ambient temperature increases The ability to heat down, if the current carrying capacity is not reduced, the cable is to heat.
Q:Is the power cable considered a fixed asset?
According to the total number of meters, such as where to where a total of how many kilometers (meters). Power system fixed assets asset management software - TU Teng fixed asset management software.
Q:Will the computer master, external DVD burner how external power supply, please click details. Thank you!
You can shop on the ground floor of a layer of waterproof carpet (that is, the rural common 'kang seats'), the wire shop in the following, at the desk to stay a outlet hole, and the jack or electrical connection. Carpet can be bought in the hardware building materials store, as the traces of tape, you can go to the big supermarket to buy a special scrub, ask the salesman on the line. Wish you the best at work
Q:What is the meaning of "cable tray: 200 * 100 middle strip" in electrical engineering
In addition to considering the security issues, there is no problem, you can use this, there is no impact on the charging situation, rest assured
Q:What is the interface between the power interface and the hard disk?
YCV-copper core XLPE insulated PVC sheathed power cable, VV-copper core PVC insulated PVC sheathed power cable. YJV-voltage level (kV) 6 ~ . the maximum allowable working temperature 90 ℃ VV-voltage level (kV) 1 ~ . allowing the maximum operating temperature of 65 ~ 70 ℃
Q:20 tons of double beam traffic acceptance standards and content which
This phenomenon is generally the audio input has an AC signal amplified by the amplifier after the results, supplies a little short and good quality of the input of the smooth exchange of spring spring to help Tong burst Kun line test, if not improved that is the receiver problem.
Q:Why my home analog TV connected to the digital TV set-top box after the screen is black and white
The simplest is to use a multimeter to find the power switch on the motherboard, to extend it to the desktop. Hands-on ability to receive the keyboard is not commonly used on the button with 2 with the bag to do the power switch to extend the line, hands-on ability in the strong words can use the remote control toy car to achieve remote control start the computer. Pay attention to open the hot hole!
Q:How to find the phone number on the 110 patch panel
Especially the external hard disk box, when used very prone to this situation
Q:What is the role of patch panels generally, why should the switch connected?
Customers want what you should have, others do not you should have. Shop to people-oriented.
