Mining rubber cables: coal mines with Shearer rubber-sheathed cables, coal use mobile rubber-sheathed cables, coal, rubber-sheathed cable shield machine.
Mining rubber cables structural features:
: Conductive wire soft core requirements to drill cables, mining machine cable is the highest; wire structure to take the following measures:
A softer fine-diameter copper single wire bundle together a small pitch, double twist. Bending torsion of the cables also affected by the insulation jacket structure, and therefore can not be considered a single wire finer pitch as small as possible.
2, using with Stranded and complex twist can improve flexibility.
3, in order to facilitate the relative sliding of the wire insulation and ease of installation and maintenance. Drill cables and a small section of the mining machine cable wire single wire should be tinned, mining machine cables of large cross-section outside the wire with package tape isolation insulation.
Two: insulating layer requires sufficient electrical insulation properties
1, using a gel content of not less than 35% of the rubber
2, the insulation thickness should be thicker than the general-purpose rubber cable
3, good electrical properties of the rubber, and a good squeeze rubber processes (eg, squeeze the rubber vulcanization continuous production line)
III: layer
The semi-conductive rubber layer, and should make the transition resistance meet the standard requirements to ensure reliable movement of the relay protection system under accident conditions.
Four: the pad core
The pad core should give full play to receive the cable red to drop, squeeze the buffering effect of the Ambassador outside diameter is too large. The requirements of rational design to fill the gap between the insulated wire
2, the mechanical properties should not be less than the requirements of the insulating rubber.
3, the core of the insulated wire adhesion.
: Into the cable structure
A smaller pitch multiples, improve the flexibility of the cable.
2, in order to ensure the mechanical strength of the earth core, earth core cross section is bigger than General Cable, a small cross-section product, using the same cross-section with the main line pipe.
3, the control wire core first separate twisted group, with the main core into the cable.
6: sheath
1, requires adequate mechanical strength, good wear resistance. Underground cable requirements of fire retardant. Therefore, neoprene, and a gel content of not less than fifty percent.
6KV mobile rubber cable sheathing have sufficient electrical insulation to improve the resistance of the sheath Corona cracking.
7: Cables To structure dense, compact, and each component of the relative sliding.
