MYP mine mobile shielding rubber sheathed flexible 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 ℃. The transition resistance of the shielding layer of the main line core shall not be higher than 3kΩ when converted to 20 ℃. The MYP cable consists of three main cores with insulation shielding and a ground wire covered with a semi-conductive rubber layer, which are twisted around the semi-conductive rubber layer cushion core to form a cable. Extruded black chlorinated polyethylene rubber sheath or black neoprene rubber sheath.
