Utility model content
The purpose of this utility model is to provide a kind of anti-bird flame retardant type optoelectronic composite cable, has solved problems of the prior art.
The purpose of this utility model realizes by following technical proposals.
A kind of anti-bird flame retardant type optoelectronic composite cable, comprise external sheath layer and be arranged in external sheath layer at least one feed line and at least one is coated with loose sleeve pipe and at least one metal wire pair of optical fiber and fine cream, described external sheath layer, and is radially back and forth shaped form along external sheath layer axial surface and distributes along the external sheath layer interlaced distribution in surface by the yellow fire retardant jacket bed of material and the red fire retardant jacket bed of material.
Further, in described external sheath layer, be provided with at least one gasket for packing.
Further, in described external sheath layer, be provided with at least one central reinforce member and bed course.
Further, in described external sheath layer by feed line, the loose sleeve pipe that is coated with optical fiber and fine cream and metal wire to being filled with water-blocking material in cable in the space at institute interval.
Further, described feed line, the loose sleeve pipe that is coated with optical fiber and fine cream and metal wire are to being coated with insulating barrier.
Further, in described external sheath layer, be disposed with from outside to inside armour and glass fiber belt.
Feature of the present utility model is:
What 1, current optoelectronic composite cable generally adopted is black oversheath, without any anti-bird measure.In the structure of cable, comprise feed line, holding wire and optical fiber simultaneously, do not take effective insulation measures, in forest or forest zone, make somebody a mere figurehead while laying, proper communication is subject to the threat of birds and disaster hidden-trouble.Colour code optoelectronic composite cable newly developed, adopt birds than more sensitive redness and yellow flame-retardant sheath material, the shaped form that the protective cover material of two kinds of colors is extruded into reciprocal winding in the time producing, just as snakelike, is used for expelling birds (natural enemy that snake is birds); Fire-retardant oversheath has the ability of fire preventing simultaneously.Meanwhile, wrapped one deck high strength glass silk ribbon outside cable core, plays insulation, fire-retardant, anticorrosion and heat insulation effect, strengthens the protection to cable core.Power line, holding wire and ferrule all adopt flame-proof material, further prevent the impact on communication such as fire.This new structure will improve the suitable environment of cable greatly, strengthens the useful life of cable.
2, traditional optoelectronic composite cable adopts double armor structure, and optical cable volume is large, stiff, electric insulation and anti-bird poor performance.Anti-bird flame retardant type optoelectronic composite cable newly developed adopts individual layer armouring, reduces cable outer diameter, strengthens flexible; Cable core wrapped one deck glass tape reinforced insulation and anti-flammability, prevent the generation of leakage fire etc.; Simultaneously, at warning coloration (red, Huang) and the natural enemy of optical cable surface design birds, substitute traditional black oversheath, prevent from that birds from flying on cable surface it is caused to damage.Cable configuration is simple, production technology maturation, and anti-bird, fire-retardant and insulating properties is good, has very strong practicality.
3, having laid the anti-bird measure that cable adopts is mainly to increase physics overcoat on its surface, as protection network, bird-resistant, light wave and sound wave bird-scaring unit etc., or uses sheathed structure optical cable.But the equal cost of these methods is high, lay difficulty large, increased the load capacity of support bar, and need long-time maintenance.Colour code cable configuration newly developed is simple, light and handy, lays conveniently, and required cost is low, without follow-up fund input.
The beneficial effects of the utility model are,
(1) reduced external diameter and the weight of cable, reduce production costs, and system of laying has been versatile and flexible.
(2) adopt red and yellow flame-retardant sheath material, can reach the effect of anti-bird and fire-proof.
(3) introducing of glass tape, has strengthened cable core protection against the tide, fire prevention, anti-creeping performance.
(4) power line, holding wire and ferrule adopt flame-proof material, further prevent the impact of forest fire on communication line.
(5) this double-color sheath structure forms by two extruding process, is convenient to promote in different cable core structures.
