What Are the Properties of the Control Cable?

Speaking of the control cable, most people have said this kind of cable. In fact, the control cable is a kind of cable used to transmit signals, automatic control and operation functions. The material used is mainly polyvinyl chloride with good insulation performance. It can be used in control and protection circuits with rated voltage below 450/750V. It is usually used more in industrial and mining enterprises and energy and transportation sectors. And a good control cable should also have some excellent performance, so do you know what performance the control cable should have?

Ⅰ. The performance of the control cable

1. Insulation performance: The control cable is mainly made of polyvinyl chloride. The voltage of 1min and 1kv cannot be broken down between the conductors. And between the conductor and the shield, even the voltage of 5mim 3kv cannot break down.

2. Capacitance: The capacitance of the control cable when working. The average value can reach 52F/KM.

3. Defense: Under the condition of 150KHZ, the average combined power is greater than 69DB/KM.

4. Number of cores: The number of cores of the control cable is large, which is mainly used as a cable for electrical equipment to transmit control signals. If the number of cores is large, it is possible to reach 61 cores. Generally, it can be produced according to the requirements of users.

5. Cross-sectional area: Most of the current and voltage of the control cable are relatively small, so its cross-section generally does not exceed 10 square meters.

However, due to the different application fields of the control cable, the performance requirements of control cable may be different in some aspects. Therefore, you still need to consider comprehensively according to your actual needs, so as to choose a control cable that suits you.

Ⅱ. Waterproof tips for industrial control cables

1. The cable head should be sealed with the sawed-off cable end. Whether it is stacked or laid, a special sealing sleeve for industrial control cables should be used to prevent moisture from infiltrating.

2. After the industrial control cables are laid, the cable head should be made in time. Strengthen the management of the cable head production process Once the cable enters the water, the breakdown phenomenon is often the cable head. A cable head of one size can prolong the overall life of the cable.

3. If there are relatively long industrial control cables, use cable branch boxs for several long cables, and each with a length of about three kilometers. For such cables, one or two cable branch boxes are also used in addition to the intermediate joint, so that once one of the cables enters the water, it will not spread to other cables.
