Abstract
The utility model discloses an absolutely-dry high combustion resistance temperature-feedback optical cable, belonging to the telecommunication transmission carrier field. The structure of the absolutely-dry high combustion resistance temperature-feedback optical cable includes that a layer of waterproofing articles is wrapped outside each beam of optical fibers, a loose tube is sleeved outside each beam of optical fibers, a central reinforcement in the center of a belting layer, loose tubes distributed around the central reinforcement and gaskets for packing, a layer of waterproofing gauze is filled between every two loose tubes and in the clearance of the packing gaskets and the belting layer; a corrugated metal strip, a reinforcing layer and an outer protective layer are sequentially wrapped outside the belting layer. In the utility model, the conventional fiber paste is substituted by two helically-twisted ultrathin waterproofing wires composed of a loose tube and a waterproofing article, thereby resources are conserved, the cost of the optical cable is reduced and the telecommunication quality is not affected; in addition, due to three combustion retarding layers, the combustion retardant performance of the optical cable is improved, the telecommunication quality is guaranteed when the optical cable runs in high temperature and the effect of the optical cable on temperature feedback is developed, thereby the utility model can be applied in the hostile environments such as tunnels and oil fields.
Description
Technical field
The utility model belongs to the optical cable technology field, relates in particular to a kind of dry type high flame retardant and presents warm optical cable.
Background technology
Along with socioeconomic continuous development, characteristics such as the track traffic mode is little with quick, large conveying quantity, pollution, efficient height become indispensable ingredient in the Traffic Configuration.Subway becomes a main mode of urban track traffic, becomes the strong instrument of the traffic conflict that solves big city, megalopolis, has effectively satisfied the traffic needs of urbanization.But because track traffic has line length, point is many, wide, passenger flow is intensive, and it is buried underground to add subway, the environment sealing, and the passenger flow evacuation is restricted, so in metro operation, underground fire hazard can not be ignored.Also paid attention to the construction of underground ventilation equipment and emergency evacuation passenger flow passage in subway construction at present and the operation, but the early warning system of fire disaster still can't reach fully in real time stage accurately in monitor procedure, rescue work after this takes place to fire disaster brings no small difficulty, and socioeconomic harm is well imagined.When fire took place, traditional communications optical cable at all can't operate as normal, therefore, provides the optical cable of high flame retardant very urgent.
The utility model content
The purpose of this utility model be in present subway construction and the operation when fire takes place, traditional communications optical cable at all can't operate as normal; The early warning system of fire disaster still can't reach fully in real time stage accurately in monitor procedure, rescue work after this takes place to fire disaster brings the deficiency of no small difficulty, and providing a kind of dry type high flame retardant to present warm optical cable, this dry type high flame retardant is presented warm optical cable and is comprised: optical fiber, be wrapped in the water-blocking material on the optical fiber, loose sleeve pipe, central reinforce member, water blocking yarn, belting layer, wrinkle steel band, enhancement Layer and external sheath layer; It is characterized in that: around the center that optical fiber 1 coated outside one deck water-blocking material 2, loose sleeve pipe 3 are enclosed within fibre bundle outside, belting layer 6 is provided with central reinforce member 4, central reinforce member 4, distribute loose sleeve pipe 3 and gasket for packing 10, filling water blocking yarn 5 in the space between per two loose sleeve pipes 3 and gasket for packing 10 and belting layer 6; , belting layer 6 outsides wrap up successively and are wrinkle steel band 7, enhancement Layer 8 and external sheath layer 9.
Described optical fiber is bend-insensitive optical fiber, and its structure is the straight cable laying core of dry type.
Described water-blocking material is ultra-fine the block water silks of two spiral strands on optical fiber.
Described enhancement Layer is that high strength is from fire resistance fibre.
Described belting layer is the low-smoke non-halogen flame-retardant band.
Described central reinforce member is the high strength rod that blocks water.
Described wrinkle steel band is the two-sided plastic-coated steel band through embossing of 0.3mm thickness.
Described external sheath layer is a high flame retardant PVC material.
The beneficial effects of the utility model are: adopting loose sleeve pipe and water-blocking material is two ultra-fine original fine cream of silk replacement that block water of formula strand in the shape of a spiral, has both saved resource, reduces the optical cable cost again, and does not influence communication quality.By three layers of flame-retardant layer, improved the fire resistance of optical cable in addition, made optical cable under hot environment, guaranteed normal communication quality, brought into play the effect of its feedback temperature simultaneously, can under rugged surroundings such as tunnel, oil field, use.
