Label in figure: 1 power wire core, 2 wire core, 3 control conductor, 4 monitor core, 5 packed layers, 6 belting layers, protect in 7 Jacket layer, 8 screen layers, 9 restrictive coatings, 11 power wire core conductors, 12 semi-conductive cloth tape layers, 13 power wire core insulating barriers, 14 is reinforced External shielding layer, 31 control conductor conductors, 32 control conductor insulating barriers, 33 control conductor metal screen layers, 41 monitor core conductor, 42 monitor core insulating barrier, and 43 monitor core metal screen layer.

Detailed description of the invention

Seeing Fig. 1, in the present embodiment, the version of shuttle car private cable is:

In the circular cross sections of cable, a wire core 2 is positioned at center, three power wire core 1 around wire core 2 in etc. Outside limit Triangle-Profile, two control conductor 3 and a supervision core 4 lay respectively between adjacent two piece power wire core 1 In space, side；A piece wire core 1, two control conductor 3 of 2, three power wire core and a supervision core 4 are common with packed layer 5 Twisted synthesizing cable constitutes cable core；This version external diameter is minimum, and stress is symmetrical, equilibrium, it is to avoid stress is concentrated, it is to avoid suffer external force And damaged or fracture, adapt to severe running environment, provide effective guarantee for safety in production.

The outside at cable core shown in Fig. 1, set gradually from inside to outside is the bag formed by wrapped semi-conductive cloth tape Belt 6, extrude formation inner restrictive coating 9, braiding constitute total screen layer 8, the appearance at total screen layer 8 is extruded with external sheath layer 9。

As it is shown in figure 1, power wire core 1 is set gradually wrapped or vertical bag on power wire core conductor 11 from inside to outside half Conductive fabric belt 12, extruded the power wire core insulating barrier 13 formed by ethylene-propylene rubber, and woven by tinned copper wire and cordage Reinforced external shielding layer 14；

As in figure 2 it is shown, control conductor 3, it is on control conductor conductor 31, to extrude formation control conductor insulating barrier 32, in control On core insulating barrier 32 processed, control conductor metal screen layer 33 is set；

As it is shown on figure 3, monitor core 4, it is to monitor that extruding formation on core conductor 41 monitors core insulating barrier 42, at prison Supervision core metal screen layer 43 is set on sight line core insulation layer 42；

The present embodiment medium power core conductor 11 and wire core 2 are formed by many tinned copper wires are stranded respectively；Control conductor Conductor 31 and monitor that core conductor 41 is to be constituted centered by many steel wire ropes and at periphery braiding tinned copper wire respectively, wherein, The steel wire rope being positioned at center plays the effect of bear external force, and tinned copper wire forms braid in periphery, tangles structure with traditional bundle Compare, greatly reduce well the fracture caused due to bending because of telescopic resilience, thus extend the service life of cable.

In being embodied as, power wire core conductor 11, wire core 2 are to use the 6th class tinned copper wire, and the fracture of tinned copper wire is stretched Long rate is 20～25, and arranges tinned copper wire and first restraint the regular structure of strand multiple strand again, and this form makes cable more soft, increases The pliability of cable；External sheath layer 9 is with neoprene rubber, chlorinated polyethylene or polyester elastomer as material, and its material is soft Soft, mechanical strength is high, tear resistance is strong, and the dependability of cable can be effectively ensured.
