Abstract
The invention relates to the technical field of insulating materials and particularly relates to a 35KV and below bonding type semi-conductive internal shielding material for a cable with extruded insulation. The 35KV and below bonding type semi-conductive internal shielding material comprises the following components in parts by weight: 50-55 parts of carbon black, 5-8 parts of an antioxidant, 0.1-5 parts of a cross-linking agent, 30-50 parts of ethylene-vinyl acetate copolymer and 8-10 parts of a lubricant, wherein the carbon black is common conductive carbon black or superconductive carbon black. The antioxidant is an antioxidant 1010 or an antioxidant 300. The 35KV and below bonding type semi-conductive internal shielding material has excellent conductive performance and low volume resistivity, so that surfaces of extruded cables are good.
Description
Technical field
The present invention relates to Insulation Material technical field, especially a kind of below 35KV adhesion type cables with extruded insulation semiconduction inner shield material.
Background technology
Semiconductive shielding layer is mainly divided into semi-conductive tape and two kinds, semiconduction plastics usually, semi-conductive tape is that fabricbase is wrapped, therefore to be not easily wrappedly convinced, and cause occurring inevitable space or pore between conductor, screen layer, insulation layer, these spaces or pore are under high-voltage field intensity, and in hole, gas ionizes, Damage to insulation layer, then generation tree branch discharge, finally causes insulation layer to puncture.So, general use semiconduction plastics as shielding material, and in current twisted polyethylene cable is produced, more advanced technique be adopt crosslinkable semiconductive shielding layer and insulation layer three-layer co-extruded go out, to guarantee closely cooperating each other, thus obtain the high pressure resistant cable of high-quality.But semiconduction plastics in the market generally use EVA as base material, this system cost compare is low, but because the VA of EVA resin easily decomposes by high temperature when extruding, and then can small-particle be produced from the teeth outwards, affect the work-ing life of cable, meanwhile, the semiconductive shieldin material of EVA base material, also be unfavorable for effective arrangement of graphitized carbon black, cause the conductivity shielding material to decline.
Summary of the invention
In order to overcome the deficiency of existing technology, the invention provides a kind of voltage rating 35KV following adhesion type cables with extruded insulation semiconduction inner shield material.
The technical solution adopted for the present invention to solve the technical problems is: a kind of below 35KV adhesion type cables with extruded insulation semiconduction inner shield material, and its component is:
Carbon black 50 ~ 55
Oxidation inhibitor 5 ~ 8
Linking agent 0.1 ~ 5
Ethene-vinyl acetate copolymer 30 ~ 50
Lubricant 8 ~ 10
According to another embodiment of the invention, comprising described carbon black is further common conductive carbon black or superconductive carbon black.
According to another embodiment of the invention, comprising described oxidation inhibitor is further antioxidant 1010 or antioxidant 300.
The invention has the beneficial effects as follows, the present invention has very excellent conductivity, and volume specific resistance is lower, extrudes cable surface better.
