MHYVR mining communication soft cable is wear-resistant, oil resistant, and corrosion-resistant, designed specifically for mining environments and meets relevant standards for mining cables. It is mainly used for connecting communication systems in mining environments such as coal mines. To ensure safe and reliable operation, the following precautions should be taken when using:
1. Installation precautions
Avoid mechanical damage: When laying, prevent the cable from being scratched or squeezed by sharp objects, and avoid affecting the shielding and insulation performance.
Minimum bending radius: The bending radius of the cable should be ≥ 10 times the outer diameter of the cable. Excessive bending may cause damage to the internal conductor or shielding layer.
Fixing method: Use specialized cable hooks or zip ties to secure, avoiding deformation or breakage caused by long-term stress.
Stay away from interference sources: Try to avoid strong electromagnetic interference sources such as high-voltage cables and frequency converters, and use metal pipes or shielding slots for protection if necessary.
2. Environmental adaptability requirements
Temperature range: The working temperature is generally between -20 ° C and+70 ° C, and exceeding this range may affect cable performance.
Waterproof and moisture-proof: In damp or wet environments, it is necessary to check whether the cable sheath is intact to avoid short circuits or insulation degradation caused by water ingress.
Flame retardant requirements: When used underground in coal mines, it must comply with mining flame retardant standards such as MT 818, and the use of non flame retardant cables is strictly prohibited.
3. Electrical safety requirements
Overvoltage use is strictly prohibited: MHYVR cables are generally rated at 300/500V and should not be used in higher voltage environments.
Shielding layer grounding: The shielding layer must be reliably grounded to reduce electromagnetic interference and improve signal transmission stability.
Avoid short circuit: When wiring, ensure that the conductor is not in contact with the shielding layer to prevent abnormal communication signals.
4. Maintenance and Inspection
Regular inspection: Check whether the outer sheath of the cable is damaged or aged, and whether the shielding layer is intact.
Avoid long-term overload: Communication cables are generally used for low-power signal transmission and cannot be used for high current power supply.
Replacement standard: If insulation resistance decreases, shielding fails, or the sheath is severely aged, it should be replaced in a timely manner.
5. Safety regulations
Explosion proof requirements: In explosive environments such as gas, explosion-proof cables that comply with GB 3836 standards must be used.
Unauthorized modification is strictly prohibited: it is not allowed to cut off the shielding layer or change the cable structure to avoid affecting the anti-interference performance.
Compliant with mining standards: Qualified products with the mining product safety mark (MA certification) must be selected.
MHYVR Mining Communication Soft CableThe safe use of communication systems involves multiple aspects such as installation, environment, electrical, and maintenance. Strictly following regulations can ensure the stable operation of communication systems and reduce the risk of malfunctions. In high-risk environments such as coal mines, cables that meet national standards must be selected and regularly inspected and maintained.
