According to the provisions of the industry standard "Fire-retardant Cables for Coal Mines" issued by the State Coal Industry Bureau, the naming content of the mining cable, that is, the model of the mining cable, is the meaning of the following.
(First, let’s review the naming of the cable)
The naming of a cable consists of eight parts
The first part is the series code M, which is the first beginning of the pinyin of the word coal;
The second part is the use characteristic code, which reflects the occasion of the cable being used. The meaning of the letter is as follows: C, for coal mining machines; D, for low temperature environments; M, for cap lamps; Y, for coal mining equipment (mobile); Z, for electric drills.
The third part is the structural feature code, indicating the structural features of the cable. The meaning of letters is as follows: B, braided reinforcement; J, with monitoring core; P, non-metal shielding; PT, metal shielding; Q, lightweight; R, wrap reinforcement.
The fourth part is the material characteristic code, and E is used to indicate that the insulation or the sheath is made of elastomeric material. This part is omitted when both the insulation and the sheath are made of rubber. E, elastomeric material.
The fifth part is the rated voltage U0/U(KV).
The sixth part is a representation of the number of power wire cores* nominal cross-sectional area. The two are connected by multiplication signs, and the unit is square millimeters.
The seventh part is a representation of the number of ground cores* nominal cross-sectional area. The two are connected by multiplication signs, and the unit is square millimeters.
The eighth part is a representation of the number of auxiliary wire cores* nominal cross-sectional area. The two are connected by multiplication signs, and the unit is square millimeters.
The fourth and fifth parts are connected by "-"; the sixth, seventh and eighth parts are connected by "+".
The mining cable models mainly include the following:
mining cables include mc cable, mcp cable, mz cable, mzp cable, myq cable, my cable, mcptj cable, myptj cable, mvv cable, mkvv cable, myjv cable, mkyjv cable, mkyjv cable, mhyv Cables, ugf cables, high voltage mining cables, 10kv rubber sleeve cables, 6kv mining cables, mobile mining cables, flame retardant cables, mcpt cables, and mining rubber sleeve cables.
