MY mine mobile rubber sheathed cable

The insulation resistance between cable insulated main line cores and between main line core and ground wire shall not be less than 100MΩ · km when converted to 20 ℃. MT type cable has two structures of 4 cores and 5 cores, consisting of 3 main cores and a ground core (one core in the 5-core cable is a control line). The cable is twisted around the cushion core, and chlorinated polyethylene rubber sheath or black neoprene rubber sheath is extruded outside. Conductive core: soft copper wire, its performance in line with GB/T3956-1997.
