Performance of control cables

Control cables belong to electrical equipment cables and play a role in transmitting control signals. They have a large number of cores, with 61 cores according to the standard. However, they can also be produced according to user requirements. The color of the insulation core of the control cable is generally black with white lettering.

The voltage and current of the control cable are very small, and its rated voltage is generally 450/750V. So its cross-sectional area generally does not exceed 0 square. In addition, control cables directly transmit electrical energy from the distribution points of the power system to the power connection lines of various electrical equipment and appliances.

Common faults in control cable lines

Common faults in control cable lines include mechanical damage, insulation damage, insulation moisture, insulation aging and deterioration, overvoltage, cable overheating faults, etc. When the above fault occurs in the circuit, the power supply of the faulty cable should be cut off, the fault point should be found, the fault should be inspected and analyzed, and then repaired and tested to prevent inconvenience in use.

Precautions for installation and wiring of control cables

1. Cables should only be used when not directly exposed to sunlight or ultra-high temperatures, but it is recommended to use pipes to prevent damage.

2. Directly laying in underground cable trenches, this environment has a small control range. Generally, the installation of cable trenches should be regularly inspected for dryness or humidity to prevent damage.

3. Avoid direct exposure to high temperatures or sunlight, as well as human damage. Due to the high temperature of cables in metal pipelines or trunking, many polymeric materials can reduce their service life at this temperature.

4. In order to facilitate future upgrades, cable replacement and isolation from surface pressure and surrounding environment, auxiliary pipelines are isolated, and auxiliary pipelines are a good method.
