Abstract
A rubber sleeve flat power cable adopts a structure of three wire cores. A conductor adopts a soft conductor combined by multistrand twisted tinned copper wires, a conductor shield layer is formed outside the conductor, an insulating layer is formed outside the conductor shield layer, an insulation shield layer is arranged outside the insulating layer, and the conductor shield layer, the insulating layer and the insulation shield layer are in cross linkage through one-step co-extrusion; a woven shield layer is formed outside the insulation shield layer, and a bifacial water-resisting belt layer and a flame-retardant glass fiber belt layer in double-layered winding package are formed outside the woven shield layer; the three wire cores are lined in a flat shape; and a sheathing layer 8 is formed outside the structure of the three wire cores and is extruded into a flat shape with isolated parvafacies. The rubber sleeve flat power cable adopts a rubber sleeve flat power cable with a rated voltage ranging from 6 kV to 35 kV, a long-term operating temperature ranging from minus 40 DEG C to 125 DEG C, large current capacity, light weight, favorable performance of the resistance to oil, moisture, climate, abrasion, corrosion and flame, and better flexibleness and stretch-proof performance.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to flattening type power cable in a kind of rubber cover.
Background technology
At present, low-voltage grade cable is still used in rail loading machine, crane, driving etc.This class current-carrying capacity of cable is little, and the cross-section of cable is big, Heavy Weight, and volume is big, and crooked half through big, is unfavorable for rolling and extends motion; Cable makes moist in adverse circumstances such as water, greasy dirt, ore are arranged for a long time and is subjected to the external force damage easily to produce breakdown fault, and useful life is short.
The utility model content
It is 6KV～35KV that the purpose of this utility model provides a kind of rated voltage, and ampacity is big, in light weight, flattening type power cable during oil resistant, moisture-proof, rubber weather-proof, wear-resisting, corrosion-resistant, that fire resistance is good are overlapped; Its long-term work temperature-40 ℃～125 ℃ has flexibility and stretch-proof performance preferably.
For achieving the above object, the solution that the utility model is taked is: flattening type power cable in a kind of rubber cover, it is three core structures, conductor adopts the tinned copper wire multiply to twist the flexible conductor of combination again, conductor is outward a conductor shield, conductor shield is outward an insulating barrier, insulating barrier is outward an insulation screen, conductor shield, insulating barrier, these three layers of co-extruded cross-linkings of insulation screen together, insulation screen is outward a woven shield, and two-sided water blocking tape layer is set outward woven shield and fire-retardant glass fiber belt layer bilayer is wrapped, and three cores become the flat pattern word order, three core structures are outward restrictive coatings 8, and restrictive coating 8 extrudes the isolated flat type of branch that is set to.
The utility model rated voltage is 6KV～35KV, voltage withstand class scope height, ampacity is big, crooked half through little, contraction crooked moving movement for a long time can frequently stand to stretch, the long-term working temperature-40～125 ℃ of allowing, have oil resistant, weather-proof, wear-resisting, corrosion-resistant, waterproof, premium properties such as fire-retardant, the cable long service life, be applicable to port and pier, steel industry stock yard, power plant coal yard etc., as the power cable of rail loading machine, crane, driving, especially as the power cable of rail loading machine and rail crane.
