Abstract
The utility model discloses a stretch-resistant and electromagnetic disturbance-resistant optical cable and belongs to the technical field of optical cables. The optical cable adopts the structure that 2-12 optical fibers are arranged in each loose tube in a straight manner; fiber paste is filled among each loose tube and the corresponding optical fibers so as to form an oil-filled straight-arrangement optical cable core; 3-12 optical cable cores are arranged at the periphery of the center reinforcer and coated by an inner sheath layer; cable paste is filled between the inner sheath layer and the loose tubes; and a water-resisting layer and an external protecting layer are sequentially coated outside the inner sheath layer. According to the cable provided by the utility model, the center reinforcer is an FRP (Fiber Reinforce Plastic) reinforcer, and a water-resisting layer made from highly tensile water-resisting yarns is arranged between the inner sheath layer and the external protecting layer, so that the electromagnetic disturbance-resistant ability of the cable is improved; as the PE (Poly Ethylene) double cover layer structure is adopted, the tensile ability of the cable is improved; and when the cable is laid overhead, the communication quality is free of the influence of the peripheral electric field, the problem that the communication quality of the traditional optical cable containing metal means is affected by the strong electric field is solved, and the technical requirement for the stretch-resistant and electromagnetic disturbance-resistant optical cable is realized. Therefore, the stretch-resistant and electromagnetic disturbance-resistant optical cable is suitable for optical communication of high-voltage electric power facility in strong electric field.
Description
Technical field
The utility model belongs to the optical cable technology field, and particularly a kind of stretch-proof anti-electromagnetic field disturbs optical cable.
Background technology
Along with socioeconomic continuous development, along with the widespread use of optical communication technique, communications optical cable applied environment in inevitably can have electric power facility.Especially the high-voltage power facility have highfield around it, and traditional communications optical cable in order to increase its tension compressive property, adopts hardware mostly, causes its communication quality in use can receive electric field and disturbs.Therefore need a kind of optical cable that can stretch-proof again can anti-electromagnetic field disturbs.
The utility model content
The purpose of the utility model receives the problem of the influence of highfield for the communication quality that solves the traditional containing metal member optical cable described in the background technology; Provide a kind of stretch-proof anti-electromagnetic field to disturb optical cable; It is characterized in that; The stretch-proof anti-electromagnetic field disturbs optical cable to be made up of optical fiber 1, fine cream 2, loose sleeve pipe 3, cable cream 4, sheath 5, water blocking layer 6, central reinforce member 7 and outer jacket 8, and 2～12 optical fiber 1 directly are placed in the loose sleeve pipe 3, fills fine cream 2 between loose sleeve pipe 3 and the optical fiber 1; Be combined into the filling type cable core of directly giving out light; Article 3～12, coat by sheath 5 around the straight centre reinforcement 7 of optical cable core, between sheath 5 and loose sleeve pipe 3, fill cable cream 4, sheath 5 outer water blocking layer 6 and the outer jackets 8 of coating successively;
Said optical fiber 1 is dispersion-unshifted single mode fiber;
The material of said loose sleeve pipe 3 is an engineering thermoplastic material polybutylene terephthalate;
Said central reinforce member 7 is fibre-reinforced plastics (FRP) reinforcement, avoids optical cable to receive electric field and disturbs;
