Abstract

The utility model discloses a heat insulation tensile flat cable, comprising a first wire core and a second wire core. The first wire core comprises three wire cores. The wire core is formed by stranding four conductors and insulating layers wrapping on the conductors, and a shielding layer wrapping on the outer side. The second wire core is provided with an upper layer and a lower layer. Each layer comprises two wire cores. The wire core is formed by stranding three conductors and insulating layers wrapping on the conductors, and a shielding layer wrapping on the outer side. The first wire core is between the upper layer and the lower layer of the second wire core, and the first wire core and the second wire core are separated by a wavy nylon skeleton. An alkali-free glass fiber filling rope is between the two wire cores of each layer of the second wire core. The outer side of the first wire core and the second wire core are wrapped by a wrapping tape layer, a braiding layer, an armor layer, and a sheath in sequence. The cable is compact in structure, reasonable in arrangement, and the nylon skeleton and the alkali-free glass fiber filling rope improves heat insulation tension performance of the cable.

Description

A kind of heat insulation tensile type flat cable

Technical field

The utility model relates to cable technology field, relates in particular to a kind of heat insulation tensile type flat cable.

Background technology

China's economic growth continuously and healthily, for cable products provides the huge market space.Along with the continuous expansion of the industry sizes such as China Power industry, data communication, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of various cables, wherein, to the demand of flat cable also in constantly increasing.

Utility model content

The utility model object is exactly for a kind of heat insulation tensile type flat cable is provided.

The utility model is achieved through the following technical solutions:

A kind of heat insulation tensile type flat cable, comprise the first core and the second core, described the first core comprises that three are surrounded by by four conductors and outside after being coated on the insulating barrier bundle strand on conductor the core that screen forms, described the second core is provided with two-layer up and down, every layer comprises that two are surrounded by by three conductors and outside after being coated on the insulating barrier bundle strand on conductor the core that screen forms, described the first core is clipped between upper and lower two-layer the second core, separated by waveform polyamide skeleton, between two cores of described every layer of second core, all accompany alkali-free glass fibre gasket for packing, the outside of described the first core and the second core is coated with belting layer successively, braid, armour and sheath.

The utility model has the advantages that: the utility model compact conformation, to arrange rationally, polyamide skeleton and alkali-free glass fibre gasket for packing have increased the heat insulation tensile property of cable, reliable operation.
