The control cable directly transmits electric energy from the distribution point of the power system to the power connection lines of various electrical equipment and appliances. The rated voltage of power cables is generally 0.6/1kV and above, and the control cables are mainly 450/750V. KVV cable is a PVC insulated control cable, full name: copper core PVC insulated PVC sheathed control cable. It is mainly used for wiring of control, signal, protection and measurement systems. KVV control cables are widely used in many fields, such as control and monitoring circuits and protection lines with voltage levels of 450/750V and below. They include low smoke and zero halogen, flame retardant and shielded cables. Due to the characteristics of low smoke and low halogen, effective flame retardant and good anti-interference performance, they are widely used in power plants, petrochemical, metallurgy and other places with higher requirements. 1. Control cables belong to electrical equipment cables, and power cables are two of the five categories of cables. 2. The standard of control cable is 9330, and the standard of power cable is GB12706. 3. The color of the insulated core of the control cable is generally black and white, and the low-voltage of the power cable is generally color separated. 4. The section of the control cable generally does not exceed 10 square meters. The power cable is mainly used for power transmission, and generally it is of large section. The section of control cable is generally small, and the maximum is generally not more than 10 square meters. In terms of the number of cable cores, the control cable is used to transmit control signals. There are many cores. According to the standard, 61 cores are more, but it can also be produced according to user requirements.

In addition, manufacturers can produce flame-retardant, fire-resistant and low smoke zero halogen control cables according to user requirements. Different types of KVV cables have different characteristics and functions. 1. Flame retardant control cables are applicable to PVC insulated and PVC sheathed control cables used in industrial and mining enterprises, energy and transportation departments, control of AC rated voltage below 450/750 V, proximity and protection of lines. 2. The fire-resistant control cable has a high fire-resistant performance. Within a certain period of time, it will not experience short circuit and short circuit fault when it is directly burned by flame. This product is suitable for various occasions with high fire risk and high fire safety importance, and is used as the connecting line between electrical equipment and control system. 3. The low smoke halogen-free control cable has low smoke discharge when heated, and it is a thermoplastic or thermosetting composition that does not contain halogen, and is suitable for use as a control connecting line in densely populated and low air density situations.
