Abstract
A kind of can the safety optical composite cable of fireproof fire-extinguishing, including the light unit at center, light unit is by optical fiber and fills fine cream between the fibers and forms；The outer concentric of light unit is coated with aluminium alloy wire layer, hard-drawn aluminium wire layer, cushion and sheath；Wherein, fire extinguishing dry mash it is filled with in cushion；Described fire extinguishing dry mash is mixed by the raw material of following weight portion: the cullet of 200 mesh 80 ~ 100 parts, auxiliary agent 10 ~ 20 parts, 30 ~ 60 parts of flyash.Present configuration is simple, applied widely, flameproof effect is good.Meanwhile, optical fiber and electrical power distribution cable are integrated, it is to avoid secondary wiring, can significantly reduce investment, cost-effective.
Description
Technical field
The invention belongs to power communication system technical field, particularly relate to a kind of electric wire with relatively high safety factor.
Background technology
China's communication of power system mainly realizes fiber optic communication by fiber plant composite overhead ground wire and All Dielectric self-support, at circuit itself without ground wire at present on main line, it is impossible to fiber plant composite overhead ground wire；Ground safe distance is not enough, cannot solve scissors crossing, tower bar strength margin is not enough, limit in the All Dielectric self-support construction of line and can realize fiber optic communication by fiber plant composite aerial phase line, optoelectronic composite cable is used can significantly to reduce investment, cost-effective, the comprehensive operation efficiency of network can be improved.
The patent that optoelectronic composite cable is relevant is the most too numerous to enumerate, and great majority all concentrate on the combination aspect of light unit and cable, often have ignored most important safety.This cable of a large amount of laying relies solely on the passive protection of insulating barrier in the wild is far from being enough, along with increase, the country of China's power consumption improve constantly for the attention degree of electric power safety, studying novel can the photoreactivation cable of Initiative Defense fire be a kind of trend.
Summary of the invention
The technical problem to be solved is for the deficiency in background technology, it is provided that a kind of can the safety optical composite cable of fireproof fire-extinguishing.
In order to solve above technical problem by the following technical solutions: a kind of can the safety optical composite cable of fireproof fire-extinguishing, including the light unit at center, light unit is by optical fiber and fills fine cream between the fibers and forms；The outer concentric of light unit is coated with aluminium alloy wire layer, hard-drawn aluminium wire layer, cushion and sheath；Wherein, fire extinguishing dry mash it is filled with in cushion；Described fire extinguishing dry mash is mixed by the raw material of following weight portion: the cullet of 200 mesh 80 ~ 100 parts, auxiliary agent 10 ~ 20 parts, 30 ~ 60 parts of flyash.
Wherein, in the light unit at center, at least contain three optical fiber, in the light unit between three optical fiber, be full of fine cream.
Preferably, sheath is made up of cross-linking polyethylene materials.
Described auxiliary agent is composed of the following components in parts by weight: calcium carbonate 2 ~ 4 parts, sodium nitrate 1 ~ 3 part, cellulose 4 ~ 6 parts, gellant 1 ~ 3 part.
Present configuration is simple, applied widely, flameproof effect is good.Meanwhile, optical fiber and electrical power distribution cable are integrated, it is to avoid secondary wiring, can significantly reduce investment, cost-effective.Using cullet, flyash etc. as the raw material of fire extinguishing dry mash, selection is extensive, low cost；Fire extinguishing dry mash is running into the situation that photoreactivation cable internal temperature is too high, can be with the substantial amounts of heat of active absorption, the preliminary formation defending fire.For extraneous naked light, fire extinguishing dry mash can well protect photoreactivation cable itself before overcoat melts, it is possible to absorbs substantial amounts of heat, and overcoat loses protective effect when, the heat absorption of fire extinguishing dry powder becomes floccule, and obstruct naked light contacts with photoreactivation cable.
Wherein, gel have single-phase disperse system and two-phase disperse system point, the gel belonging to two-phase disperse system is that little molecule inorganic drug colloidal particles are present in liquid with network structure, has thixotropy, also referred to as suspendible gel, preferably gel aluminum hydroxide.
All raw material itself is nontoxic, "dead", will not discharge harmful substance, will not contaminated foundation and subsoil water, there is good environment protecting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Embodiment 1: as it is shown in figure 1, a kind of can the safety optical composite cable of fireproof fire-extinguishing, including the light unit 5 at center, light unit 5 is by least three optical fiber 4 and fills fine cream between the fibers and forms；The outside of light unit 5 is coated with aluminium alloy wire layer 3, hard-drawn aluminium wire layer 2, cushion 1 and sheath 6 the most with one heart.
Wherein, fire extinguishing dry mash it is filled with in cushion；Described fire extinguishing dry mash is mixed by the raw material of following weight portion: the cullet of 200 mesh 80 ~ 100 parts, auxiliary agent 10 ~ 20 parts, 30 ~ 60 parts of flyash.
Described auxiliary agent is grouped into by following weight portion: calcium carbonate 2 ~ 4 parts, sodium nitrate 1 ~ 3 part, cellulose 4 ~ 6 parts, gellant 1 ~ 3 part.
Sheath is made up of cross-linking polyethylene materials.
Embodiment 2: a kind of can the safety optical composite cable of fireproof fire-extinguishing, wherein, described fire extinguishing dry mash includes the cullet 80 parts of 200 mesh, auxiliary agent 10 parts, 40 parts of flyash；Wherein, 10 parts of auxiliary agents are made up of calcium carbonate 3 parts, sodium nitrate 2 parts, cellulose 3 parts, gellant 2 parts.
