Mining cable marker
Specification
Mine the number of cores of the cable core cable specifications. Specifications: 4,8,12,16,20,24,28,32,36,40,44,48,52,56,60.
Specification, code-named
Cable nominal star stranded group × 4 × wire nominal diameter.
Fourth, the technical performance
1) conductors to comply with the the GB3953 provisions of the soft round copper wire, the nominal diameter of 1.4mm.
2) insulation of halogen-free polyethylene plastic, and made the four colors of red, green, white, blue.
3) The lines of the color of the four different core of the insulated wire twisted into star quads, quads different Stranding pitch sparse around the non-hygroscopic ribbons of different colors to distinguish between.
4) the cable core.
a) In addition to the four core mining cable, the other specifications of the cable core outer stranded direction are right, adjacent layers twisted in the opposite.
b) mining cable end A line group sort the provisions of Q/321023KLA65-2001.
c) The cable core polyester fibers coated the GB/13849.3 provisions waterproof tape, and then coated with fire-retardant glass ribbon.
d) The cable core filler wire rope for fire-retardant glass.
5) shielding in accordance with the different performance of the cable longitudinal packet mode longitudinal package copper layer thickness of 0.1mm copper plastic tape and the aluminum layer thickness of 0.2mm plastic composite tape or aluminum jacket.
PE care - low smoke, halogen free, flame retardant PE material
Armored layer - GB4175 provisions of galvanized steel strip, with a nominal thickness of 0.3mm
PE outer sheath - low smoke, halogen-free flame retardant PE jacket material
6) cable's electrical performance should be consistent with the provisions of Table 2
Fifth, the use of features
A mining cable ambient temperature -20 to +70 ° C
2 mine permissible working temperature of cable conductor should not exceed 70 ℃.
3 mining cable laying ambient temperature should not be less than -10 ℃.
4 shielded cable can be used for the need to set up the shield of the electrification of the track circuit section.
5 aluminum sheath mine cable has good shielding effect can be used for the electrification of the track circuit section of the trunk or strong electrical interference region.
6 cable bending radius: non-armored cable should not less than 10 times the cable diameter; armored cable should not less than 15 times the cable diameter.
Six, the length of delivery
500m and above the mine cable of not less than 50% of the total length of delivery; 50m to 250m short segment of mine cable delivery length does not exceed 5% of the total length of delivery.
The cable length measurement error should not exceed ± 0.5%.
Under the agreement, the first branch of the Tianjin Cable Plant allows delivery of any length cable
