Description :
Control cables belong to electrical equipment cables, and power cables are two types of cables. Common faults in control cable circuits include mechanical damage, insulation damage, insulation moisture, insulation aging and deterioration, overvoltage, and cable overheating faults.
Main performance of control cables:
1. Insulation resistance: Each core wire is grounded with the remaining cores, and the control cable is greater than 10000M Ω· km, while the HYAT cable is greater than 3000M Ω· km;
2. Insulation electrical strength: In terms of the insulation electrical strength of the product itself, it does not break through between the conductors as a whole, ensuring that the overall advantage value is obvious during use. Nowadays, many people still want to know if it is good when choosing. After recognizing these basic advantages, everyone can make a reasonable choice according to the location and certain characteristics when choosing;
3. Rated voltage (U0/U): 450/750V;
4. Working capacitance: average value of 52 ± 2nF/km.
The long-term allowable working temperature of the control cable conductor used in coal mines is 70 ℃, and the cable laying temperature should not be lower than 0 ℃. The allowable bending radius for control cables used in coal mines: For cables with armor or copper tape shielding structures, it should not be less than 12 times the outer diameter of the cable. For flexible cables with a shielding layer structure, it should not be less than 6 times the outer diameter of the cable. For unarmored cables, the outer diameter should not be less than 6 times that of mining cables.
Control cables are mainly used for transmitting control signals, so they are PVC insulated and PVC sheathed control cables suitable for industrial and mining enterprises, energy and transportation departments, and for controlling and protecting circuits with AC rated voltage below 450/750 volts.
Control cables belong to electrical equipment cables, and the color of insulated wire cores is generally black with white lettering. In addition, low-voltage power cables are generally color coded, and the cross-section of control cables generally does not exceed 10 square meters. Control cables are used for transmitting control signals, with a large number of cores. According to the standard, there are 61 cores, but they can also be produced according to user requirements.
Tianjin Cable Factory Branch adheres to the production principle of "survival through quality, development through reputation" and has won high praise from both new and old customers. The company has scientific internal management, a sound quality assurance system, honesty as the foundation, and a good reputation, which is highly trusted by domestic and foreign customers.
