Preferably, separation layer is formed by the wrapped periphery at cable core of banded Halogen polyester.

Compared with prior art, the utility model has following beneficial effect:

A kind of high temperature resistant type rolling stock multiple-twin cable that the utility model provides, by adopting the multipair work of twisting againSkill, is stranding into core after combination core body, more multiple combination core bodys and Halogen core body is formed after concentric strandCable core. For the cable core through strand forms with one heart, determine that the key of its pliability is the pliability of central core.Because Halogen core body is as central core, to add Halogen core body and adopted soft Halogen material, its pliability is wantedLower than the pliability of core, therefore can increase the pliability of cable core. Make it meet locomotive for flexibilityRequirement. Meanwhile, the insulating barrier of a kind of high temperature resistant type rolling stock multiple-twin cable provided by the utility model is adoptedMake with polyether-ether-ketone engineering plastics, because polyether-ether-ketone engineering plastics resistance is higher, dielectric loss is less,The highest long-term permission serviceability temperature of conductor can reach 260 DEG C, electric performance stablity. Finished cable temperature resistant grade reaches200-260 DEG C, has improved current-carrying capacity and the cable overload capacity of cable. And can meet low cigarette, Halogen, resistanceCombustion, oil resistant, heatproof, etc. the requirement of locomotive cable.

Detailed description of the invention

For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with accompanying drawingSpecific embodiment is described in detail.

As shown in Figure 1, Fig. 1 is a kind of high temperature resistant type rolling stock multiple-twin cable that the utility model proposesStructural representation, comprises combination core body 1, screen layer 4, separation layer 3, restrictive coating 5 and Halogen core body 2.

Combination core body 1 forms by many cores 6 are stranded. When concrete enforcement, every combination core body 1 is by twoCore 6 is stranded to be formed. Stranded by core 6, can improve the pliability of core 6. Multiple combination coresThe stranded formation cable core of body 1 and Halogen core body 2,2 and 6 combination core bodys 1 of Halogen core body are by stranded formationCable core. When concrete enforcement, also can be using a Halogen core body 2 as central core and multiple combination core body 1 twistClose formation cable core. For the cable core through strand forms with one heart, determine that the key of its pliability is the soft of central coreSoftness. Because Halogen core body is as central core, to add Halogen core body and adopted soft Halogen material, it is softSoftness will, lower than the pliability of core, therefore can increase the pliability of cable core, makes it better adapt to locomotiveThe requirement of vehicle cable.

Separation layer 3 is coated on the periphery of cable core, and while specifically enforcement, separation layer 3 is wrapped by banded Halogen polyesterPeriphery at cable core forms. Separation layer 3 peripheries are coated with screen layer 4 and restrictive coating 5 from inside to outside successively. LogicalCross separation layer 3, screen layer 4 and cable core can be kept apart, improve the shield effectiveness of screen layer 4.

As shown in Figure 2, a kind of high temperature resistant type rolling stock multiple-twin cable institute that Fig. 2 provides for the utility modelThe structural representation of disclosed core, core 6 comprises conductor 61 and insulating barrier 62, insulating barrier 62 is coated onThe periphery of conductor 61. When concrete enforcement, described core 6 is low-smoke non-halogen flame-retardant cross linked insulation core. SoCan meet the low cigarette, Halogen of locomotive cable, fire-retardant requirement, the security that improves locomotive cable. Concrete realShi Shi, insulating barrier 62 is made up of polyether-ether-ketone engineering plastics. Because polyether-ether-ketone engineering plastics resistance is higher,Dielectric loss is less, and the highest long-term permission serviceability temperature of conductor can reach 260 DEG C, electric performance stablity. Finished cableTemperature resistant grade reaches 200-260 DEG C, has improved current-carrying capacity and the cable overload capacity of cable. And can meet lowCigarette, Halogen, fire-retardant, oil resistant, heatproof, etc. the requirement of locomotive cable.

The conductor 61 comprising in core 6 is formed by five class tin-coated copper skein silk systems. When concrete enforcement, five class platingsThe strand mode processed of tin copper wire is that regular concentric type single line is stranded. So, can put forward the flexibility of conductor 61, therebyImprove the flexibility of cable.

The above, be only preferably detailed description of the invention of the utility model, but protection model of the present utility modelEnclose and be not limited to this, any be familiar with those skilled in the art the utility model disclose technology modelIn enclosing, be equal to replacement or changed according to the technical solution of the utility model and utility model design thereof, allWithin should being encompassed in protection domain of the present utility model.
