Abstract

The utility model discloses an optic fibre is fire resisting cable for mixed ore, include by the oversheath with set up control core in the oversheath, the cable body that constitutes of sinle silk and duo gen power core, control core and duogen power core outer peripheral face respectively the cladding have control core insulating layer and a power core insulating layer, power core insulating layer outer peripheral face respectively the cladding have a power core shielding layer, control core insulating layer and ground sinle silk outer peripheral face respectively the cladding have the control core sheath and the sinle silk sheath, be provided with fiber core in the oversheath, it is fine around the covering to have set gradually ceramic flame retardant coating and glass outside by in to at the oversheath internal surface, and it has the packing of fire -retardant adhesive tape to be located fine the filling around the covering of glass. The utility model discloses advantage lain in the increasing function of cable for intelligent management in the pit gives security, can realize the integration of power network and intelligent network, and the volume is less, lay the convenience, do not need secondary wiring, increase ceramic flame retardant coating simultaneously, improve the security performance greatly.

Description

Optical Fiber Composite mine fire-resistant cable

Technical field

This utility model relates to field of cables, especially relates to a kind of Optical Fiber Composite mine fire-resistant cable.

Background technology

Mine cable structure commonly used at present is made up of power wire core, ground connection core and control conductor, and this structure realizes the conveying of electric power and relevant instrument and meter control only.To more intelligent signals, figure Image relaying, multimedia transmission cannot realize.The material adopted: it is EP rubbers that insulant adopts, although it has excellent insulating properties and ageing-resistant performance, but its disadvantage is inflammable, poor stability；Sheath adopts flame-retardant chloroprene rubber, though having good flame retardant effect, but releasing a large amount of poisonous gas during burning, people can be made to suffocate, once fire occurs to bring very big difficulty to work of suing and labouring time serious；Additionally when fire occurs, the integrity of circuit can not ensure, normal power supply, information transmission cannot realize.

Summary of the invention

This utility model purpose is in that to provide a kind of multiple functional, that safety is high Optical Fiber Composite mine fire-resistant cable.

For achieving the above object, this utility model can take following technical proposals:

Optical Fiber Composite mine fire-resistant cable described in the utility model, including the cable body being made up of with the control conductor, wire core and the Duo Gen power wire core that are arranged in described oversheath oversheath, control conductor insulating barrier and power wire core insulating barrier have been respectively coated by it at described control conductor and Duo Gen power wire core outer peripheral face, it is respectively coated by dynamic conductor screen at described power wire core insulating barrier outer peripheral face, is respectively coated by control conductor sheath and wire core sheath at control conductor insulating barrier and described wire core outer peripheral face；Being provided with fiber cores in oversheath, jacket inner surface is disposed with pottery fireprotection layer and glass lapping layer from outside to inside outside, is positioned at described glass lapping layer and is filled with flame-retardant rubber strip filling.

This utility model advantage is in that to add the function of cable, provides for downhole intelligentization management and ensures, it may be achieved the fusion of power network and intelligent network；And small volume, lays conveniently, it is not necessary to secondary wiring；Increase pottery fireprotection layer simultaneously, be greatly improved security performance.
