The shielding of the power line core edge adopts a semi conductive extruded layer or a semi conductive tape coating. The cross-sectional area of single core cables ranges from 4 square millimeters to 400 square millimeters. The cross-sectional area of the three core grounding cable ranges from 4 square millimeters to 150 square millimeters.
Working conditions for MYP mining cables
The rated voltage (U0/U) is 0.66/1.14. The bending radius of the cable is 6 times the diameter of the cable. The grounding core of the cable should be well grounded. 1、 The naming of mining cables consists of eight parts:
Part of it is the series code M, which is the phonetic prefix of the coal character; The first part is the use of characteristic codes, reflecting the occasions in which mining cables are 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.
