How to distinguish between power cables and control cables?
With the development of the times, the demand for electricity is everywhere, from small household lighting to large factory power generation, all of which require wires and cables to connect to the power supply. However, there are many types of wires and cables on the market, including control cables, power cables, etc. What is the difference between their uses and places of use?

 

                                                                                                                           cable wire


1. The difference of rated voltage
 The power cable is mainly used for the main line power transmission in the power system, and its voltage is generally above 0.6~1KV. The control cable is mainly used for the power link of electrical equipment, and its voltage is 450~750V.


2. Different thickness of insulation and sheath
For power cables and control cables of the same specification, the insulation and sheath thickness of the power cables are thicker than those of the control cables.


3. Differences in the implementation of standards
Power cable is the second of the five categories of cables, and it is implemented in accordance with the GB12706 standard. The control cable belongs to the electrical equipment cable category, and the implementation standard is GB/T9330.
 

4. Differences in cable specifications
Power cables are mainly used to transmit power, and the specifications used are too large, which can reach 500 square meters, while the cross-sectional area of ​​control cables is relatively small, generally not exceeding 10 square meters.


5. The difference in the number of cable cores
According to the requirements of the number of cable cores, the power cable is generally 5 cores at most according to the requirements of the power grid, while the control cable is used to transmit control signals, and the number of cores is more. Production.


When purchasing wires and cables, we need to choose different types of wire products according to specific needs, such as RV, RVB, RVS and other cables for household appliances. According to different use occasions, choose the sheath layer with different functions such as insulation and waterproof. Zhengzhou Jinshui Wire & Cable Group is a professional cable production company, producing standard wire and cable products according to the needs of different customers.
