Mine cable is short
for fire-retardant cable for
coal mines . Provisions "coal mine fire cable" issued by the State Coal Industry Bureau industry standards,
mining ore that is named after the contents of the
cable model with the following meanings cable.
The name of the cable consists of eight parts
The first part is series code M, the first prefix of the pinyin of coal.
The second part is the use of characteristic code, reflecting the occasions used by the cable. The meanings of the letters are as follows: C, for coal mining machine; D, for low-temperature environment; M, cap lamp; Y, for coal mining equipment (moving); Z, for electric drilling.
The third part is the structural feature code, indicating the structural characteristics of the cable. The meanings of the letters are as follows: B, weaving strengthening; J, with monitoring core; P, non-metallic shielding; PT, metal shielding; Q, lightweight;
The fourth part is the material feature code, E is used to indicate that the insulation or sheath is made of elastomer material. This part is omitted when rubber and insulation are used. E, elastomer material.
The fifth part is rated voltage U0/U(KV).
The sixth part is the representation of the number of power cores * nominal cross-sectional area. The two are connected by a multiplication sign and the unit is square millimeters.
The seventh part is the representation of the number of ground cores* nominal cross-sectional area. The two are connected by a multiplication sign and the unit is square millimeters.
The eighth part is the representation of the number of auxiliary cores * nominal cross-sectional area. The two are connected by a multiplication sign and the unit is square millimeters.

Hanger Bolt
Hanger Bolts have threaded areas at both ends, a lag screw thread at one end and machine screw thread on the other. They are designed for insertion into a pre-drilled hole and are ideal for overhead application, usually in a wall or ceiling. Plain finish, or bare metal, may or may not have a coating of light oil to resist corrosion. Plain finish, or bare metal, may or may not have a coating of light oil to resist corrosion.
