General description
Multiple conductor cable manufactured with three soft drawn copper conductors with semiconductor shield over the conductor, thermosetting ethylene propylene rubber individual insulation (EPR), semiconductor insulation shield and soft drawn electrostatic individual copper shield. They have two bare soft drawn copper neutral conductors and a ground check conductor insulated with yellow thermosetting material, filled circular section and thermosetting chlorinated polyethylene outer jacket (CPE).
Main applications
Mining cables, MP-GC type EPR-CPE, are used to supply electrical power to semi-movable mining equipment or fixed mining installations.
Suitable for use in horizontal underground spaces, in ducts or direct burial, in overhead installations, and for other installations in heavy industry generally.
Characteristics
Maximum operation voltage: 5 000 to 15 000 V.
Maximum operation temperature: 90° C.
Soft drawn copper conductor, flexible construction, in sizes from 13, 3 to 253, 4 mm2 (6 AWG to 500 kcmil).
Copper tape electrostatic shield.
Chlorinated polyethylene extra heavy duty outer jacket (CPE), resistant to mechanical maltreatment (tear and abrasion), oil, acids and alkalis.
Phase conductors are identified by semiconducting tape with letters.
No flame propagation characteristic.
Black outer jacket.
Advantages
Meet the no-flame propagation test (NMX-J-192).
Thermosetting insulation provides a higher thermal stability.
Can be installed in wet locations. Their extra heavy duty jacket will support heavy mining work.
Ground check conductor allows a safer operation of the electrical system, since it is possible to constantly monitor the insulation resistance of the phase conductors.
Awarded the MSHA certification (CFR Title 30 Federal Regulations).
