This section GB/T 12972 Part 2.
This Part replaces GB 12972.2-1991 "mining rubber-sheathed cables - Part 2. Rated voltage 0.66/1.14kV Mining and below
Coal cutter flexible cable. "
This section compared with GB 12972.2-1991 main changes are as follows.
--- Name changed to "rated voltage 1.9/3.3kV and below Shearer flexible cables";
--- Increasing the rated voltage UCP-1.9/3.3kV Shearer flexible cable (Excerpts of Table 1);
--- Rated voltage U0/U of 0.66/1.14kV cable specifications by the conductor cross-section 35mm2 ~ 95mm2 to 35mm2 ~
120mm2 (1991 edition Table 2b; Excerpts of Table 3);
--- Remove the original specification table control core parameters (1991 edition Table 2a and 2b);
--- Added "line of control for not less than the core-core 3-core, wire core nominal cross-section of not less than 2.5mm2" content (edition 6.4);
--- Remove the XJ-00A-type rubber content (1991 version 5.3.1 and 5.3.2);
--- Adjustment improve cable insulation resistance at 20 ℃ minimum time (1991 Version 5.1, this version 7.1);
--- 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 "instead of GB/T 12666.2" single wire or cable vertical burning test method "(1991 edition
Table 4; edition 7.2).
