MZ drill rubber sheathed cable MZ rubber sheathed cable specifications and uses Supply products Mining cable technical requirements: 1. The conductor structure adopts the current universal conductor structure, ensuring that the DC resistance of the conductor is qualified at 20 ℃ before use; 2. Both the power core and the ground core are extruded with rubber insulation layer. The extrusion of the core requires a smooth, round, and tight appearance, without any adverse phenomena such as vulcanized rubber, burnt particles, bamboo joints, and explosion (breakage).

Mining cable is the abbreviation for flame-retardant cable used in coal mines. According to the industry standard "Flame retardant cables for coal mines" issued by the Coal Industry Bureau, the naming content of mining cables, that is, the meaning of the model of mining cables, is as follows.
1、 The naming of cables consists of eight parts:
*Part of it is the series code M, which is the pinyin of coal characters with * prefix;
The second part is the use of characteristic codes, reflecting the occasions in which the cable is used. The meaning of the letters is as follows: C, used for coal mining machines; D， Used in low-temperature environments; M， Used for hat lamps; Y， For mobile coal mining equipment; Z， Used for electric drills.
The third part is the structural feature code, which represents the structural features of the cable. The meaning of the letters is as follows: B, weaving reinforcement; J， Equipped with monitoring cores; P， Non metallic shielding; PT， Metal shielding; Q， Lightweight; R， Strengthen the wrapping.
The fourth part is the material characteristic code, represented by E indicating that the insulation or sheath is made of elastic material. When both insulation and sheath are made of rubber, this section is omitted. E， Elastic material.
The fifth part is the rated voltage U0/U (KV).
The sixth part represents the number of power wire cores multiplied by the nominal cross-sectional area. The two are connected by a multiplication sign, with the unit being square millimeters.
The seventh part represents the number of ground wire cores multiplied by the nominal cross-sectional area. The two are connected by a multiplication sign, with the unit being square millimeters.
The eighth part represents the number of auxiliary wire cores multiplied by the nominal cross-sectional area. The two are connected by a multiplication sign, with the unit being square millimeters.
