Utility model content
The ultra-thin-wall that the purpose of the utility model is to provide a kind of with special combustibility insulate EMU single Cable overcomes the deficiencies in the prior art, is combined using internal cable core and external cable core, facilitates the repair and replacement of cable core, together The unidirectional waterproof membranes of Shi Caiyong, waterproof layer improve the water resistance of cable, while the good anti-pressure ability of low-smoke non-halogen flame-retardant ductility By force.
To solve the above problems, technical solution adopted in the utility model is as follows:
A kind of ultra-thin-wall with special combustibility insulate EMU single-core cable, including cable core, warp resistance layer, absolutely Edge layer, shielded layer, waterproof layer, corrosion-resistant coating, waterproof membrane, external sheath layer, the cable core include internal cable core, external cable core, institute It states internal cable core outer surface and wraps up one layer of external cable core, the external cable core includes the first outside cable core, the second outside cable core, institute It states the first outside cable core to connect with groove by convex block with the second outside cable core, aramid fiber is sequentially installed on the outside of the external cable core Silk braiding constitute warp resistance layer, insulating layer, aluminum-alloy wire braiding constitute shielded layer, high elastic rubber waterproof layer, acid and alkali-resistance, The erosion resistant coating that the high molecular material of oil resistant is constituted, low smoke halogen-free flame-retardant polyolefin external sheath layer, the waterproof membrane are mounted on anti-corrosion Lose the outside of layer.
Further, the cable core is tinned copper conductor or bare copper conductor.
Further, first outside cable core is loop configuration, and is equipped with left and right two with the second outside cable core junction A convex block, the convex block are semi-circular structure, and second outside cable core is cirque structure and is connect with the first external cable Place is equipped with two semi-circular recesses in left and right.
Further, the waterproof membrane be unidirectional waterproof membrane by tetrafluoroethene it is aggregated made of high-molecular compound.
Further, the insulating layer is mineral insulation layer and material is mica tape.
Compared with prior art, the implementation result of the utility model is as follows:
A kind of ultra-thin-wall insulation EMU single-core cable with special combustibility described in the utility model, using interior Portion's cable core and external cable core are combined, and facilitate the repair and replacement of cable core, while using unidirectional waterproof membrane, waterproof layer improves electricity The water resistance of cable, while the good anti-pressure ability of low-smoke non-halogen flame-retardant ductility is strong, production efficiency is high, simple in structure.
