Flame-retardant explosion-proof fire-fighting communication optical cable

Abstract

The invention discloses a flame-retardant explosion-proof fire-fighting communication optical cable which comprises optical fibers, a framework, an aramid fiber tape, polyurethane foam, a mica tape, an explosion-proof net and a polyurethane sheath. A plurality of mount slots are uniformly distributed along the circumstance of the framework, and are disposed axially; a plurality of optical fibers are penetratingly connected in each mount slot which is filled with fiber paste; the framework is lapped with the aramid fiber tape, the aramid fiber tape is coated with the polyurethane foam, the polyurethane foam is lapped with the mica tape, and the mica tape is tightened by yarns; the explosion-proof net covers the mica tape, and is coated with the polyurethane sheath. The optical cable is featured by high temperature resistance, flame resistance, constant temperature, flame resistance, high insulativity and high explosion protection properties, and is applicable to fire-fighting communication and various extreme conditions.

Description

Technical field: [0001] The invention relates to a flame-retardant and explosion-proof fire-fighting communication optical cable. Background technique: [0002] In the traditional optical cable technology, due to the limitations of optical cable materials and structures, there is currently no communication optical cable that can be used in high-fire areas or areas with special requirements for high temperature, flame resistance, and explosion-proof. The occurrence of fire is usually accompanied by combustion and explosion. In the event of a fire, ordinary optical cables will cause direct physical and chemical damage to the optical fiber under the action of high-temperature combustion and explosion, resulting in a sharp increase in optical fiber attenuation or even fiber breakage, which cannot guarantee the smooth flow of normal communication at all. The work has caused great resistance and inconvenience, which affects the time and efficiency of fire rescue and may cause hu...
