Nanning control cable control cable MKVV323 * 1.5

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.

　　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.

　　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.

　　Precautions for installation and wiring of control cables:

　　1. Under the eaves. Standard LAN cables can only be used when not directly exposed to sunlight or ultra-high temperatures, and it is recommended to use pipelines. Ultraviolet (UV) - Do not use cables without UV protection in direct sunlight environments;

　　2. On the exterior wall. Avoid direct sunlight on the wall and human damage. Heat - The temperature of cables in metal pipes or cable trays is very high, and many polymer materials will reduce their service life at this temperature;

　　3. In a pipeline (made of plastic or metal). If in a pipeline, pay attention to the damage of plastic pipes and the thermal conductivity of metal pipes. Mechanical damage (repair cost) - Fiber optic cable repair is very expensive, requiring at least two terminations at each breakpoint;

　　4. Suspended applications/overhead cables. Consider cable sag and pressure. Whether the cable is directly exposed to sunlight;

　　5. Directly laying in underground cable trenches has a limited control range. The installation of cable trenches should be checked regularly for dryness or moisture levels. Grounding - If the shielding layer of the control cable needs to be grounded, the corresponding standards must be followed;

　　6. Underground pipelines. For future upgrades, cable replacement, and isolation from surface pressure and surrounding environment, installing auxiliary pipelines for isolation is a better method. But don't expect the pipeline to remain dry forever, as this will affect the choice of cable type. Water - Moisture in twisted pair cables in a local area network can increase the cable's capacitance, thereby reducing impedance and causing near end crosstalk issues.
