Mining Cable-MYJV、MYJV22、MYJV32
Features
Product Structure:
MYJV series cables adopt all-plastic structure, and the inner core is made of high-quality cross-linked polyethylene (XLPE) insulation material, which has excellent electrical properties and high temperature resistance. Depending on the model, the outer structure of the cable is also different:
MYJV: No armor, suitable for environments without external forces, widely used in coal mines, underground pipelines and tunnels.
MYJV22: Equipped with steel belt armor, it enhances the cable's ability to resist mechanical external forces and is suitable for places susceptible to external forces.
MYJV32: Equipped with fine steel wire armor, it further improves the cable's tensile strength and is suitable for more severe working environments.
Environmental conditions and working conditions for use:
Working temperature: The long-term working temperature shall not exceed 90℃, the short-term overload temperature shall not exceed 160℃, and the short-circuit temperature may reach 250℃. The cable should be operated under the above temperature conditions to ensure safety and stability.
Laying temperature: The cable laying environment temperature should not be lower than 0℃. If used in a low temperature environment, the cable needs to be preheated to prevent damage.
Minimum bending radius: The minimum bending radius of the cable is 15 times the outer diameter of the cable. This requirement must be followed when laying to avoid damage to the cable.

Want to learn more? Check out our electrical cable most frequently asked questions.
What is the minimum bending radius of cross-linked polyethylene insulated power cables for coal mines?
When laying cables, the minimum bending radius should be 15 times the outer diameter of the cable. This is to avoid damaging the insulation layer of the cable when bending and ensure its long-term stable operation.
What are the differences between the armor designs of MYJV22 and MYJV32?
MYJV22: Equipped with steel belt armor, it can withstand certain mechanical external forces and is suitable for underground coal mines, tunnels and other places.
MYJV32: It uses fine steel wire armor, which has stronger tensile strength than steel belt armor and is suitable for environments with large tensile forces.
What is the operating temperature range of the cable?
Working temperature of MYJV series cable:
Long-term working temperature: 90℃;
Short-term overload temperature: up to 160℃;
Short-circuit temperature: up to 250℃. These temperature ranges enable MYJV cables to operate stably in high temperature environments.
What is the rated voltage of the MYJV series cables?
MYJV series cables are suitable for the following rated voltages:
0.6/1kV, 3.6/6kV, 6/10kV, 8.7/10kV. These rated voltages are suitable for coal mines and other industrial power transmission systems to ensure that the cables can withstand long-term working loads.
What are the applicable scenarios for MYJV, MYJV22, and MYJV32 cables?
MYJV series cables: suitable for fixed laying environments such as underground coal mines, tunnels, underground pipelines, and suitable for places without external forces.
MYJV22 series cables: equipped with steel belt armor, suitable for environments with certain mechanical external forces, such as underground coal mines, tunnels, etc.
MYJV32 series cables: equipped with fine steel wire armor, suitable for places with large mechanical tension, and widely used in environments requiring high-strength mechanical protection.
