Abstract
The invention relates to a super-flexible fireproof power cable adopting ceramic silicone rubber insulation and a stainless steel interlocking sheath, which effectively solves the problems that the insulating layer of a conventional cable is easy to absorb water to get damp, the bending radius of the cable is large. The cable adopts the solution that the cable comprises a cable conductor, wherein a lapping inner layer is arranged in the outer layer of the cable conductor; a ceramic silicone rubber insulating layer is extruded on the cable conductor; an oxygen separation strap is lapped on the ceramic silicone rubber insulating layer; the exterior of the lapping inner liner layer is wrapped with an interlocking armor layer made of stainless steel straps. The cable adopts a novel and unique structure, fundamentally solves the problem that the insulating layer of the cable absorbs water and gets damp, enhances the flame retardance function, greatly reduces the bending radius, improves the flexibility, and improves the fire emergency guarantee level.
Description
Technical field
The present invention relates to electric wire manufacturing technology field, particularly a kind of ceramic silicon rubber insulation, stainless steel lock armo, super fire resistant flexible power cable.
Background technology
The flexible fire-proof cable of existing marketing, adopts mica tape multilayer lapped insulation, and the sheath technique of the coated embossing of copper strips argon arc welding requires cable producing, laying and must do strict dry, moistureproof processing during joint; Cable produces, lay and require bending radius to be not less than 40 times of cable size etc., and producing, lay, joint link slightly neglects, very easily make cable insulation water suction make moist, lay rear once fire disaster emergency power transmission, because ground short circuit cannot start fire-fighting equipment, cause the unnecessary loss of user, coverage ratio is lower.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the present invention's object is just to provide a kind of ceramic silicon rubber insulation, stainless steel lock armo, super fire resistant flexible power cable, has effectively solved the existing cable insulation problems such as easily water suction is made moist, Cable Bending Radius is large.
Its solution is, comprise cable conductor, the skin of cable conductor is provided with wrapping lining-layer, is extruded with ceramic silicone rubber insulation layer on cable conductor, on ceramic silicone rubber insulation layer, be surrounded with oxygen barrier band, the lock armo layer that wrapping lining-layer outer wrapping is made by stainless steel band.
Novel structure of the present invention is unique, has fundamentally solved the problem that cable insulation water suction is made moist, and has promoted fire-retardant fireproof function, has significantly reduced Cable Bending Radius, increases its flexibility, improves the emergent guarantee grade of cable fire.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
By Fig. 1, provided, the present invention includes cable conductor, the skin of cable conductor 1 is provided with wrapping lining-layer 2, is extruded with ceramic silicone rubber insulation layer 3 on cable conductor 1, on ceramic silicone rubber insulation layer 3, be surrounded with oxygen barrier band 4, the lock armo layer 5 that wrapping lining-layer 2 outer wrapping are made by stainless steel band.
The insulating layer material of product of the present invention adopts ceramic silastic material to extrude, meeting under the prerequisite of GB electric property, this material is at 350 degrees Celsius and above flame or without under flame condition, start hardening, reach as high as 3000 degrees Celsius, along with temperature raises, rapidly by Low fire ceramic shape, hard complete housing has good protective effect to cable line, can ensure circuit unimpeded operation under fire hazard environment, and ceramic silicon rubber has elastomeric material characteristic at normal temperatures, waterproof moisture-resistance is remarkable, fundamentally having solved moistureproof problem. oxygen barrier flame-retardant layer 4 adopts low smoke and zero halogen glass oxygen barrier band to carry out wrapped, this technique significantly promotes the anti-flaming function of cable, lock armo layer 5 adopts stainless steel band and lock armo technique, Cable Bending Radius reduces (by 40 times of diameters, being reduced to 12 times of diameters), the present invention can adopt novel ceramic silicon rubber as the disposable expressing technique of insulation, thoroughly eliminate original technique because of the potential safety hazard that cable body makes moist and brings to fire-fighting dynamical system on the one hand, simplified joint technique, increase substantially again on the other hand the production efficiency of such cable, and lock armo layer 5 adopts stainless strip and lock armo, increase substantially the flexibility of cable, can adopt support mounting process, save crane span structure expense, increase the agility of installing, avoid the existing installation hidden danger of former technique, in addition with stainless steel band, substitute copper strips, make significantly to save production, installation cost becomes possibility, with after the wrapped cable insulation of oxygen barrier band, make fire-retardant fireproof functional promotion of the present invention.
Novel structure of the present invention is unique, has fundamentally solved the problem that cable insulation water suction is made moist, and has promoted fire-retardant fireproof function, has significantly reduced Cable Bending Radius, increases its flexibility, improves the emergent guarantee grade of cable fire.
