MKVVR 4 * 2.5 Mining Control Cable Price

MKVVR cable is a type of flame-retardant control flexible cable used in mining. Here is a detailed introduction about it:

1. Structural composition:
-Conductor: It is usually made by twisting multiple strands of thin copper wire, which has good conductivity and flexibility, making it easy to lay and install in complex environments.
-Insulation layer: PVC material is used, which has good electrical insulation performance and can effectively prevent current leakage, ensuring the normal operation of the cable.
-Sheath: Also made of polyvinyl chloride material, it provides protection for the internal structure of the cable, preventing wear, corrosion, and other mechanical damage to the cable underground.
2. Performance characteristics:
-Good flame retardant performance: In environments with flammable and explosive gases such as coal mines, good flame retardant performance can effectively reduce the risk of fire and ensure the safety of personnel and equipment.
-Good flexibility: As a flexible cable, it has good flexibility and can adapt to the complex wiring environment and equipment connection requirements underground in coal mines, making it easy to bend and lay in narrow spaces.
-Stable signal transmission: Suitable for control and monitoring circuits with AC rated voltage of 450/750V and below, as well as connecting wires for electrical instruments in distribution equipment, ensuring stable signal transmission.
3. Applicable scenarios:
-Mainly used underground in coal mines to provide power and signal transmission for various equipment such as ventilation fans, water pumps, lighting equipment, monitoring systems, etc.
-It also has certain applications in other places with high requirements for cable flexibility and flame retardant performance, such as special environments in chemical, metallurgical and other industries.

In summary, MKVVR cables have the characteristics of flame retardancy, flexibility, and stable signal transmission, making them an ideal choice for control and signal transmission in special environments such as coal mines. When using, it is important to choose the appropriate model and specifications, and ensure the quality and reliability of the cable to ensure safe production and normal operation. 1.
