Description
Technical field
The invention belongs to electric power Material Field, be specifically related to a kind of cable plastic material.
Background technology
Cable is by this section of system from step-down distribution substation exit to user side in power system.In transmitting line to the large multi rack of cable between two electric poles, and be mostly exposed to outdoor, therefore high to the performance requriements of cable, good mechanical property and insulated fireproof performance should be possessed.
Utilization in recent years along with productive life electric wire is growing and universal, the requirement increase of cable is very fast, and along with expanding economy, also more and more higher with the requirement of outer plastic cement insulating material to cable, it requires the performances such as soft, wear-resisting, low temperature resistant.And more appearance is fireproof high-temperature resistant cable, fireproof high-temperature resistant cable as its name suggests, refers under regulation test conditions, sample is burned, after removing test burning things which may cause a fire disaster, flame spread only in limited range, residual flame or residual to burn in limiting time can the cables of self-extinguish.Its basic characteristic is: be likely burned in case of fire and can not run, but can stop spreading of the intensity of a fire.Generally, electric wire, just in case catch fire, can be limited in subrange burning, not produce and spread, keep other various equipment, avoid resulting in greater loss.Life security and property safety can be protected to a greater extent, so use comparatively general.
And no matter consider from mechanicalness, showing tremendous enthusiasm chemical resistance and disaster prevention angle, inner raw material is impaired all plays vital effect to maintain in its normal operation in protection for cable outer layer plastic material, in embody rule process, cable material must all physical strength be high, stretch-proof, anticorrosive, still can ensure under unexpected fire condition or temporarily ensure that it normally runs simultaneously.
