Abstract
The utility model provides a novel fire -retardant power cable of compound resistance to compression of optic fibre, belongs to the cable application, constitutes insulation core at the peripheral crowded crosslinked polyethylene insulating layer that is wrapping of conductor, and insulation core has formed the cable core with the light unit, and the cable core is equipped with outward around the fire -retardant area of package in proper order, does not have the fire -retardant oxygen layer that separates of steamed low cigarette, and the resistance to compression armor does not have steamed low cigarette flame retardant polyolefin oversheath. Simple structure adopts the copper conductor to provide the magnitude of current, and holistic size reduces, has reduced the material and has used sparingly cost. The light unit be nonmetal center tube oleamen filled type light unit, has the mechanical properties excellence, all uses environmental protection material moreover, can not cause the pollution to the environment, and when the conflagration took place, burning rate was slow for the low smoke and zero halogen material, releases minute quantity smog when burning, and is just nontoxic harmless to the human body, has avoided the casualties that the secondary calamity caused.
Description
Technical field
This utility model belongs to cable application field, is specifically related to a kind of novel optical fiber composite compression-resisting flame-proof power cable.
Background technology
Fast development along with intelligent grid, State Grid Corporation of China actively develops and contacts close intelligent power end with resident living, intelligent residential district in all parts of the country, building are rised sheer from level ground, have fiber optic communication and the staple product in Optical Fiber Composite Lan Shi State Grid Corporation of China implementation " four nets merge " strategy of electric power transfer function concurrently, the national standard that particularly in April, 2013 promulgated, require to have realized the at county level of fiber-optic transfer at public telecommunication network and fiber to the home mode should have been used to build with the communications facility of Shangcheng District, development and residential housing.This also by having high fire-retardance, forward position, market pushed to by the OPLC Optical Fiber Composite cable of safe environment protection type.
Summary of the invention
This utility model purpose specifically provides a kind of novel optical fiber composite compression-resisting flame-proof power cable, has high fire-retardance, low smoke, zero halogen and crushing resistance, meets the requirement of present development trend.
This utility model is achieved in the following ways a kind of novel optical fiber composite compression-resisting flame-proof power cable, conductor is formed by many copper conductors are stranded, extrude crosslinked polyetylene insulated layer in conductor periphery and constitute insulated wire cores, 4 insulated wire cores constitute a cable core with light unit, described cable core is externally provided with wrapped inhibiting tape, gap between cable core and wrapped inhibiting tape is filled with halogen-free flameproof gasket for packing, LSOH anti-flaming oxygen barrier layer is extruded outside described wrapped inhibiting tape, LSOH anti-flaming oxygen barrier layer is externally provided with resistance to compression armor, halogen-free and low-smoke flame-retardant polyolefin oversheath is extruded outside resistance to compression armor；Described light unit is by colored optical fiber, PBT Loose tube, water resisting optical fiber ointment, aramid yarn reinforcement, TPU material guards forms, and described colored optical fiber is arranged in PBT Loose tube, is filled with water resisting optical fiber ointment between colored optical fiber and PBT Loose tube, PBT Loose tube outer cladding aramid yarn reinforcement, extrudes TPU material guards outside aramid yarn reinforcement.
Described colored optical fiber number is 1 to 144.
