MYQ is a lightweight, mobile rubber-sheathed cable for coal mines, commonly used for underground lighting and signal transmission equipment. Let's take a look at what MYQ cable is.
Based on the standard: MT818.9-2009
Cable Conductor: The cable core conductor is annealed copper, with a cross-section that meets the required specifications. The maximum diameter of a single power core conductor is no more than 0.26mm.
Cable Insulation and Sheath: The insulation's physical and mechanical properties conform to the XJ-30A specification in GB7594.2; the sheath's physical and mechanical properties conform to the XH-03A specification in GB7594.7.
Flame Retardant Performance Requirements: The flame retardant performance of the finished cable meets all test requirements in the MT386 standard.
MyQ Light Rubber-Sheathed Flexible Cable for Mining: What Does the Code Mean?
The first part is the type code, M, for coal mines.
The second part is the application code, which reflects the application in which the cable is intended. The letters mean as follows: C - For coal mining machines; D - For low temperature environments; M - For cap lamps; Y - For mobile coal mining equipment; Z - For electric drills.
The third section is the structural feature code, which indicates the cable's structural characteristics. The letters mean as follows: B - Braided reinforcement; J - With monitoring core; P - Non-metallic shield; PT - Metallic shield; Q - Lightweight; R - Wrap reinforcement.
The fourth section is the material feature code, with E indicating that the insulation or sheath is made of an elastomer. This section is omitted if both the insulation and sheath are made of rubber. E - Elastomer material.
