Technical field
The utility model relates to a kind of high temperature resistant anti-tear flexible cable.
Background technology
Current domestic high temperature-resistant cable mainly contains three kinds: fluoroplastics, silicon rubber, mineral insulated cable.These three kinds of cables all have certain not foot point from price and structure.Fluoroplastics are expensive, although high temperature resistant can be nearly 260 ℃, when high temperature, can decompose, discharge toxic gas, and cold flow properties is poor, easy to crack, not flexible.Silicon rubber intensity is low, and tear resistance is poor.
The disclosed < < of Chinese patent ZL201020149725.4 high temperature fire resisting electric cable > >, it consists of conductor, the positive and negative winding braid of high temperature yarn, the overlapping lapping layer of synthetic mica tape, high temperature yarn braid and protective layer from inside to outside successively.Although fire-resistant, resistant to elevated temperatures object that this cable reaches, its complex structure, cost are high, and mica layer easily comes off when crooked, affects fire resistance, and pliability is low.
The disclosed < < of Chinese patent ZL201020134721.9 high temperature-resistant cable > >, its structure is that conductor adopts tinned copper wire, and conductor surface insulation is that polytetrafluoroethylene, oversheath are silicon rubber.This cable is the most widely used high-temperature cable in the market, but its bending property is poor, in the occasion of demand flexibility, can not use, and tin coating is the highest can only bear 150 ℃, at the above tin layer of this temperature, easily comes off, and ordinary silicon rubbery intensity is low, not tension.
So, for the flexible anti-tear cable of high temperature, still have improved place.
Utility model content
The purpose of this utility model is to provide a kind of conventional silicone rubber high temperature resistant cable that can substitute in the market, and temperature resistant grade and silicon rubber are consistent, and tear strength improves greatly, and the high temperature resistant anti-tear flexible cable of low cost of manufacture.
The technical scheme that realizes the utility model object is a kind of high temperature resistant anti-tear flexible cable, comprises conductor, insulating barrier and high temperature fiber silk layer; The insulating barrier of the outer setting silicon rubber material of described conductor, forms insulated wire cores; Described high temperature fiber silk layer be two superimposed spiral dredge around and the contrary structure of two-layer winding direction.
For further reinforced insulation performance, high temperature resistant anti-tear flexible cable also comprises the second insulating barrier that is coated on high temperature fiber silk layer outside.
Insulated wire cores can be that single core can be also multicore structure, and for multicore structure, described insulated wire cores is tangent between two multicore structure, and per share conductor outside all arranges insulating barrier; The restrictive coating of silicon rubber material is set between described insulating barrier and high temperature fiber silk layer, is packed layer between restrictive coating and insulating barrier.
As further improvement, high temperature resistant anti-tear flexible cable also comprises the restrictive coating that is arranged on high temperature fiber silk layer outside.
In order further to strengthen its resistant to elevated temperatures performance, described high temperature resistant anti-tear flexible cable also comprises thin curling around being arranged on outermost high temperature twining package tape.
Described conductor is sub-thread conductor or multiply conductor.
Adopted technique scheme, the utlity model has following beneficial effect: (1) high temperature fiber silk of the present utility model layer adopt the spiral of left side+right superposing type thin around, insulation or sheath sulfuration remain on semi-cure state, high temperature fiber silk is wrapped in semi-cure insulation or jacket surface, guarantee that filament and silicon rubber can stick together, not loose, Cable Construction Design is simple, for other high temperature tension flexible cable, cost is low, easy to make, and customized lengths is long, under frequent movement or winding condition, can normally work, improve useful life.
(2) the utility model squeezes one deck thin insulating or sheath over cure pipe as oversheath full cure in high temperature layer of filament outside, interior external insulation or sheath are held tightly together, tear strength, resistance to elevated temperatures are good, therefore can meet users' instructions for use, and improve the reliability of cable laying and the use of coiling occasion, prevent insulation or sheath cracking.
