Description
Technical field
The utility model relates to the cable technology field, is specifically related to the fire-resistant frequency conversion of a kind of low smoke and zero halogen cross-linking radiation high flame retardant and uses power cable.
Background technology
Power cable is meant the cable that is used to transmit and distribute electric energy, be usually used in the underground electrical network in city, power station lead line, industrial and mining enterprises in-line power and cross the river, excessively in the submarine transmission circuit in sea.In power circuit, the shared proportion of cable increases just gradually.Power cable be master in electric power system in circuit in order to transmission with distribute the cable product of high-power electric energy, comprising 1-500KV and above various electric pressure, the power cable of various insulation.Along with the reach of science with the society progress, power industry to cable performance require increasingly high.Conventional cable (YJV, VV series) only has common transmission and distribution ability, and is not good enough at aspect of performance such as fire-resistant, fire-retardant.Its insulating barrier of low smoke and zero halogen crosslinked cable (WDZ-YJE) in the past is non-flame retardant type, only be that sheath material adopts flame-proof material, so its fire resistance is lower, generally only reaches C level flame retardant rating.And some special enterprises and unit need the cable of high flame retardant, fire-resistant premium properties, and along with the increase of enterprise or personal security's consciousness, the cable demand of the fire-resistant series of high flame retardant can significantly increase surely.
The normal wrapped production efficiency of mica tape that adopts of traditional power cable is low, and mica powder comes off and causes environmental pollution, and its dust can damage labourer's health.When mica tape lap-joint or tension variation, can cause wrapped defective, cause this place not fire-resistant.And low smoke and zero halogen crosslinked cable (WDZ-YJE) in the past, its cross linked insulation layer are non-flame retardant type, so its fire resistance is lower.
The utility model content
The purpose of the utility model provides the fire-resistant frequency conversion of a kind of low smoke and zero halogen cross-linking radiation high flame retardant and uses power cable.
For reaching the foregoing invention purpose; The technical scheme that the utility model adopted is: provide the fire-resistant frequency conversion of a kind of low smoke and zero halogen cross-linking radiation high flame retardant to use power cable, it is characterized in that: comprise low smoke and zero halogen restrictive coating, copper strips screen, low smoke and zero halogen lapping layer, annealed copper strand wire, potteryization silicon rubber flame retardant coating and low smoke and zero halogen cross-linking radiation polyolefin insulation layer; Said annealed copper strand wire extrudes a potteryization silicon rubber flame retardant coating outward, and potteryization silicon rubber flame retardant coating extrudes a low smoke and zero halogen cross-linking radiation polyolefin insulation layer outward; Said annealed copper strand wire is wound with a low smoke and zero halogen lapping layer outward, and the low smoke and zero halogen lapping layer is provided with a copper strips screen outward, and the low smoke and zero halogen lapping layer extrudes a low smoke and zero halogen restrictive coating outward.
Preferably, said annealed copper strand wire is set to the 1-5 root and does not wait.
Preferably, the cross section of said annealed copper strand wire is circular, fan-shaped or bow-shaped structural.
In sum, the fire-resistant frequency conversion of low smoke and zero halogen cross-linking radiation high flame retardant that the utility model provided is enhanced productivity through adopting potteryization silicon rubber directly to extrude flame retardant coating with power cable greatly, reduces production costs, and reduces production environment and pollutes; And, all adopt the high flame retardant refractory material to make its fire resistance, fire-resistance property all improve greatly from insulating to each layer of sheath.
