Description
Technical field
The invention belongs to the power cable field, be specifically related to a kind of environment-friendly type subway electricity consumption power cable.
Background technology
Traditional power cable for subway is that brown paper is being surrounded on the conductor, or adopts the alternate surface of conductors that surrounds with polypropylene of brown paper, is full of insulating oil then therein, realizes electric power transfer by this structure.The easy leakage of oil of the power cable of this structure, simultaneously this structures shape this power cable inflammable, explosive, and can produce a large amount of dense smoke when catching fire, so, when breaking out of fire, be easy to cause great casualties and heavy losses economically.
For subway station service power cable, fire can keep the electric power system operate as normal when taking place be the key factor that guarantees personal security in the tunnel.Therefore, will protect electric power system not to be subjected to the influence of fire in a period of time that fire takes place, comprising giving the fire pump room fire alarm system, evacuating the electricity consumption of emergency lighting system and smoke discharging pipe system etc.Traditional with brown paper or adopt the alternate surface of conductors that surrounds of brown paper with polypropylene, be full of the power cable of this spline structure of insulating oil then therein, have very big flame-retarding power.When big fire had influence on cable, cable was difficult to avoid can not burn, and simultaneously, can produce a large amount of dense smoke after the ignition of cable burning, brought bigger trouble for fire-fighting and rescue work.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, and a kind of environment-friendly type subway electricity consumption power cable with high flame retardant, waterproof and dampproof, low smoke and zero halogen is provided.
The technical scheme that solution the technology of the present invention problem is adopted is this environment-friendly type subway electricity consumption power cable, conductor, inner semiconductor layer, insulating barrier, out semiconductor layer, metal screen layer are arranged from inside to outside successively, and that metal screen layer has outward is waterproof and dampproof, low smoke and zero halogen, special outer jacket with high flame retardant.Special outer jacket includes water blocking layer, high density polyethylene (HDPE) sheath, oxygen barrier layer, armour, low smoke and zero halogen sheath from inside to outside successively; Or include water blocking layer, low smoke and zero halogen sheath, oxygen barrier layer, armour, high density polyethylene (HDPE) sheath from inside to outside successively.
When in the subway during breaking out of fire, the present invention can guarantee can not cause at short notice electrical power transmission system to interrupt, and burning is produced simultaneously that the halogen acid gas burst size is little, smoke density is low.
