Foreword
GB/T 12972 "mining rubber flexible cable" is divided into 10 parts.
--- Part 1. General requirements;
--- Part 2. Rated voltage 1.9/3.3kV and below Shearer flexible cables;
--- Part 3. rated voltage of 0.66/1.14kV Shearer shielded monitor enhanced flexible cables;
--- Part 4. Rated voltage 1.9/3.3kV and below Shearer metal shield soft cable;
--- Part 5. rated voltage of 0.66/1.14kV and following mobile rubber soft cable;
--- Part 6. Rated voltage 6/10kV and below the metal shield Flexible cables with monitoring;
--- Part 7. rated voltage 6/10kV and below shielded rubber-sheathed cables;
--- Part 8. Rated voltage 0.3/0.5kV drill cables;
--- Part 9. Rated voltage 0.3/0.5kV light mine mobile rubber soft cable;
--- Part 10. Miner 's cap lamp cords.
This section GB/T 12972 Part 7.
The partial substitution of GB 12972.7-1991 from the date of implementation of the "mining rubber-sheathed cables - Part 7. Rated voltage 3.6/6kV screen
Shield rubber-sheathed cables. "
This section compared with GB 12972.7-1991, the main changes are as follows.
--- Name changed to "rated voltage 6/10kV and below shielded rubber-sheathed cables";
--- Increase the rated voltage 6/10kV cable of UYPT and UYDPT content (Excerpts of Table 1 and Table 4);
--- Rated voltage of 3.6/6kV cable specifications by the conductor cross-section 16mm2 ~ 50mm2 to 16mm2 ~ 120mm2
(1991 edition Table 2a and Table 2b; Excerpts of Tables 2 and 3);
--- Remove the XJ-30A-type rubber content (1991 version 5.3.1);
--- Adjustments to improve the insulation resistance value Insulation of power core at 20 ℃ (Excerpts Table 5);
--- Cable partial discharge test sample type test routine test for the revised (1991 edition Table 4; Table 6 edition);
--- Cable burning test by the GB/T 18380.1 "cables under fire conditions test - Part 1. single insulated wire or
Cable vertical burning test method "to replace the original GB/T 12666.2" single wire or cable vertical burning test method "(1991
Version of Table 4; edition 7.2).
