Abstract
The invention discloses an optical cable for rail transit, belonging to the technical field of optical cables. An optical fiber is straightly placed in a loose sleeve, and fiber paste is filled between the loose sleeve and the optical fiber to combine an optical fiber core. The cross section of a framework is of a cross-shaped structure, the cross-shaped structure of the framework is used for partitioning the periphery of the framework into four spaces, the framework is made of compound carbon fiber, one to three optical fiber cores are respectively arranged in each space around the framework, a water-blocking wire and cable paste are filled between the optical fiber cores and in a gap between the optical fiber cores and the framework, and are wound and coated by using a bundling yarn to form an optical cable core which is then sequentially coated with an aluminum-plastic composite belt layer and an outer sheath to form the optical cable for the rail transit. According to the optical cable, by using the framework made of the carbon fiber, the tension strength of the optical cable and the space in the framework are ensured, the self weight of the optical cable is reduced, so that the performance of the optical fiber in the loose sleeve is not influenced, and thus the optical cable is conveniently laid and installed; the defect that a thunder is easily introduced into a room by a metal reinforcer optical cable is eliminated, and the optical cable is suitable for a communication system of the rail transit.
Description
Technical field
The invention belongs to optical cable technology field, particularly a kind of track traffic optical cable.
Background technology
Along with the high speed development of modern railway transportation, the track traffic optical cable transmission problem that some cause because structural design is unreasonable also highlights further.If the band of fixed sturcture is on the impact of Loose tube profile, metal reinforcement increases own wt and is vulnerable to effects of lightning, and the use without supporting member makes optical cable easily be affected on optical fiber when being subject to natural compression and then affect communication performance.This just needs the communications optical cable developing a kind of new structure, ensures that communication performance does not affect by the restriction of own material function and external force.
Summary of the invention
The object of the invention is, in order to solve the problem described in background technology, a kind of track traffic optical cable to be provided, to it is characterized in that, track traffic light cable wrap draw together optical fiber 1, Loose tube 2, the silk 3 that blocks water, skeleton 4, prick yarn 5, plastic-aluminum combined belt 6 and oversheath 7, optical fiber 1 is directly placed in Loose tube 2, fine cream is filled between Loose tube 2 and optical fiber 1, be combined into fiber cores, the xsect of described skeleton 4 is decussate texture, the decussate texture of skeleton 4 will be separated into 4 spaces around skeleton, the material of skeleton 4 is carbon fiber reinforce plastic, 1 ~ 3 fiber cores is set in each space around skeleton 4 respectively, block water silk 3 and cable cream is filled in space between fiber cores and between fiber cores and skeleton 4, prick yarn 5 by fiber cores, skeleton 4, block water silk 3 and cable cream voluble wrapping formation Cable Core, plastic-aluminum combined belt 6 is coated by Cable Core, oversheath 7 is coated on plastic-aluminum combined belt 6, form track traffic optical cable.
Described plastic-aluminum combined belt 6 is double-layer overlapping lapping structure.
The material of described oversheath 7 is polyurethane elastomer, has the performance of environmental protection flame retardant.
The present invention has following features: adopt skeleton structure, by the destruction of external mechanical stress, can ensure that communication performance is unaffected propping up better protection fiber cores in space; Skeleton 4 adopts carbon fiber reinforce plastic material, its tensile strength is higher than steel 3 ~ 4 times, rigidity is higher than steel 2 ~ 3 times, fatigue durability is higher than steel 2 times, weight ratio steel are light 3 ~ 4 times, possess high strength, high tenacity, high-modulus, corrosion-resistant, light weight, the advantage such as non-conductive while guarantee should have performance; Fine cream is filled in around fiber cores inner fiber 1, and at Loose tube and the uniform filling cable cream between silk that blocks water, effectively play resistance effect, make optical fiber not be subject to the erosion of water, the use of the silk 3 that simultaneously blocks water, strengthens block-water effect further; Use double-layer overlapping wrapped plastic-aluminum combined belt 6 form LA light armor, play moistureproof and anti-rodent and bait destruction, the effect of more protection, and there is lightweight and flexible nature, be convenient to laying; Oversheath adopts environmental protection flame retardant polyurethane elastomer sheathing material, the objectionable impuritiess such as not leaded, cadmium and many bromides.
Beneficial effect of the present invention is, the use of carbon fiber new material ensure that the tensile strength of optical cable, greatly reduces optical cable own wt, is convenient to lay install; Eliminate metal reinforcement optical cable and easily draw the defect that thunder enters the room.Use the carbon fiber reinforce plastic skeleton of high strength, intraskeletal space is guaranteed, and Loose tube inner fiber performance is not affected.The present invention can be applied to humidity, the environment of external force extruding of paddling, be subject to.
