Description

Warping strength anti-dilatory electric cable for coal mining machine

Technical field

The utility model relates to the cables manufacturing technical field.

Background technology

Electric cable for coal mining machine is for the power supply of coal-winning machine or similar devices, need follow coal-winning machine during work all around moves around, cable all is subject to the impact of serious dilatory, extruding, bending and torsion and coal cinder, existing cable is controlled core and is unable to bear such flexural deformation, in not long situation, control core with regard to fracture in use, can only stop production to overhaul, not only increase maintenance cost and time, and had a strong impact on the normal operation in colliery.

The utility model content

The utility model is to overcome the deficiency that common cable exists, and a kind of warping strength anti-dilatory electric cable for coal mining machine with high bending performance is provided.

The utility model comprises cable core, in the described cable core outside, sets gradually lapping layer and neoprene external sheath layer; Described cable core comprises three groups of power cores, one group of ground wire core and one group of control core; Every group of power core comprises respectively power core combined conductor, in the power core combined conductor outside, sets gradually power line core insulation layer and power conductor screen; Described ground wire core comprises ground wire core conductor, at described ground wire core conductor arranged outside ground wire core insulating barrier; Described control core comprises three stranded eradication edge cores, in the three stranded eradication edge cores outsides, sets gradually coating layer and outer high temperature resistant slippage belt; Every eradication edge core comprises respectively controls the core combined conductor, outside controlling the core combined conductor, sets gradually interior high temperature resistant slippage belt and control line core insulation layer.

The utility model power core combined conductor and core combined conductor processed are twisted again in tension and are spun on the synthetic fibre yarn and form by tinned copper wire respectively.The utility model is rational in infrastructure, and anti-bending is dilatory, and serviceability is good, and product has the performances such as oil resistant, fire-retardant, anti-daylight, anti-ozone, acid and alkali-resistance, chemical-resistant reagent simultaneously.Can meet the performance requirement of mine with electric cable for coal mining machine.
