The pre-fabricated optical-fiber composite low-voltage cable is characterized in that an optical fiber unit is also arranged between the external protective layer and the insulating layer; a branch protective body is arranged at the front end of the pre-fabricated optical-fiber composite low-voltage cable; and a cable outlet and an optical-fiber outlet are arranged at the end part of the branch protective body respectively. The pre-fabricated optical-fiber composite low-voltage cable has the advantages of simple structure, relatively low manufacturing cost, long service life, high usage strength, and the like.
Description
Technical field
The utility model relates to a kind of low-voltage cable, especially relates to the compound low-voltage cable of a kind of preformed fibers.
Background technology
As everyone knows, Optical Fiber Composite low-voltage cable (being called for short OPLC) is to be used at the low pressure communication access net, and optical fiber with the low-voltage power wire routing, is realized that intelligent electric meter is to the family, cooperate passive optical network technique, business such as the collection of carrying power information, intelligent power two-way interactive, the fusion of many nets.Thereby realize that power optical fiber is to the family.The characteristics of Optical Fiber Composite low-voltage cable maximum are the functions that has merged optical fiber communication and electric power transfer.The enterprise of China cable producer research and development at present and production Optical Fiber Composite low-voltage cable is considerably less, and it is less that main cause is to possess simultaneously the enterprise of cable and optical cable research and development, fusion, production capacity.
There is following problem mostly in some Optical Fiber Composite low-voltage cables of Cun Zaiing in the market: one, optical fiber is vulnerable to extruding in cable; Two, there is the stretching problem in the optical fiber pay off rack during stranding; Three, cable temperature has influence to optical fiber property.In addition, because Optical Fiber Composite low-voltage cable termination is (box of cable and optical fiber separates) that will insert different boxes respectively, and the optical fiber of the compound low-voltage cable of ordinary optic fibre and cable are made and are encased with sheath together, Optical Fiber Composite low-voltage cable termination need be cut open during wiring, cable and fiber unit are separated, and twine with adhesive tape respectively, will result in hand cramps to construction like this, and not enough to the security protection of cable and fiber unit, there is more hidden danger.
Summary of the invention
The utility model mainly is at the above-mentioned technical problem of existing in prior technology, provide a kind of simple in structure, manufacturing cost is relatively low, long service life, the compound low-voltage cable of preformed fibers that working strength is high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the compound low-voltage cable of a kind of preformed fibers; comprise at least one conductor and outer jacket; conductor is provided with insulating barrier outward; be provided with gasket for packing between outer jacket and the insulating barrier; it is characterized in that also being provided with between described outer jacket and the insulating barrier fiber unit; the compound low-voltage cable front end of described preformed fibers is provided with branch's protective, and described branch protective end is respectively equipped with cable outlet and optical fiber outlet.The utility model can separate cable and optical cable in advance according to the length (distance that cable box and optical fiber box separate) of incoming end in the termination; separately the place carries out the injection moulding sealing and forms branch's protective; easy for installation; cable has solved the problem of potential safety hazard preferably with fiber unit can directly outlet be connected with incoming end with optical fiber by cable outlet.
As preferably, described fiber unit comprises optical fiber and is set in the loose sleeve pipe of outer fiber that loose sleeve pipe is arranged with oversheath outward, is filled with the paste compound between described loose sleeve pipe and the optical fiber.Light harvesting fibre and power transmission and distribution cable are avoided the secondary wiring, can effectively reduce expenses such as construction, networking, and the light unit is compatible mutually with power cable long-term work temperature.
As preferably, be provided with non-metal reinforcement member between described loose sleeve pipe and the oversheath.The utility model possesses stronger mechanical performance, and as shock resistance and good anti-pressure measurement performance, adaptive capacity to environment is strong.
As preferably, be provided with band between described outer jacket and the fiber unit.Simple in structure, reasonable in design.
As preferably, described branch protective adopts the plastics one injection molded.Manufacturing cost is cheap relatively, and manufacturing process is easy.
Therefore, the utlity model has simple in structure, characteristics such as manufacturing cost is relatively low, long service life, working strength height.
