Abstract

The utility model provides a silicon-based rubber cable, which comprises three groups or more than three groups of conductors, insulating layers, belting layers, and protective sleeves, wherein, each group of conductors are respectively extruded with insulating layers, the insulating layer is divided into an inner insulating layer and outer insulating layer, which are extruded for two times by the silicon-based rubber with different components into a double layer structure, and each group of conductors with insulating layers are wrapped on the previous flexible belting layer together during the cabling process and placed into the protective sleeve. The utility model uses the above technical proposal, especially the belting layer, the inner protective layer and a metal protective layer is arranged inside the protective sleeve, the utility model can effectively improve the mechanical tensile strength of the protective sleeve of the cable, and the minimum tensile strength is improved from 5 N/mm <2> to 10 N/mm <2>; the cable is arranged with shielding layer, the exterior boundary is not affected during the transmission of electric energy, and simultaneously the counter external interference performance is good; after a metal armour layer is arranged, the utility model can satisfy the special requirements of the cable.

Description

A kind of silicon-based rubber cable
Technical field:
The utility model relates to a kind of electric wire, particularly relates to the transmit electric power silicon-based rubber cable of usefulness of a kind of electric wiring.
Background technology:
Needs along with high speed development of national economy and landscaping, various overhead wires go underground one after another, cable market is developed rapidly, at present under the comparatively abominable occasion of environment, often use the silicon rubber insulation electric wire as occasions such as high temperature or low temperature, corrosive atmospheres, its as fired basis instinct has satisfied the specific demand of various engineerings.But because existing silicon rubber insulation electric wire is relatively simple for structure, the mechanical and physical performance of main insulating material silicon rubber is poor than polyvinyl chloride and vinyon, use to occur cable cover(ing) cracking, decortication bad phenomenon sometimes under the adverse circumstances occasion, influence is normally used.
The utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of silicon-based rubber cable that uses under the adverse circumstances occasions such as high low temperature, corrosion that is applicable to is provided.
The purpose of this utility model is achieved in that described a kind of silicon-based rubber cable; comprise that three groups and three groups are with upper conductor; insulating barrier; belting layer 5 and sheath; every group of lead is extruded with insulating barrier separately; described insulating barrier is divided into inner insulating layer 2 and external insulation layer 3; divide secondary to extrude by the heterogeneity silicon-based rubber and constitute double-decker; each lead common wrapped last layer belting layer 5 in the stranding process of organizing the tape insulation layer is placed in the sheath; described sheath is disposed with inner protective layer 6 from inside to outside; metal sheath 7 and external protection 8; gap between described belting layer 5 and each the group lead is provided with packing material 4; described inner protective layer 6 extrudes for silicon-based rubber or the wrapped formation of high-low temperature resistant material band, and described external protection 8 is the silicon-based rubber layer.
Described metal sheath 7 is a metal screen layer 7, and described metal screen layer 7 is metal knitted silk or the wrapped formation of metal tape, and described metal knitted silk is copper wire or tinned copper wire, and described metal tape is a copper strips.
Described metal sheath 7 is the metal armouring layer.
Described belting layer 5 is thermally resistant fiber glass band or the wrapped formation of fire-retardant band that has the oxygen barrier effect.
Described packing material 4 is high-low temperature resistant material or the refractory material compatible mutually with insulating material, comprises glass fibre or nonmetallic mineral.
Described lead 1 is that three groups or three groups of thick core main traverse lines add three groups thin core subpolygons and constitute, and every group of lead is made of many stranded circular copper wires.
The beneficial effects of the utility model are: owing to use technical scheme described in the utility model; particularly in sheath, be provided with belting layer 5, inner protective layer 6, metal sheath 7; the utility model can effectively improve the mechanical tensile strength of cable cover(ing), and minimum tensile strength is from original 5N/mm 2Be increased to 10N/mm 2Cable does not produce interference after screen is set to external world when electric energy transmitting, anti-simultaneously external disturbance performance is preferable; The special instructions for use that the metal armouring layer can satisfy cable is set.
