The composite optic-fiber low-voltage cable integrates an optic-fiber cable and an electric power transmission and distribution cable, so secondary wiring can be avoided, and the expense for construction, network building and the like can be effectively reduced. The composite optic-fiber low-voltage cable is used as an access solution for an intelligent electric network user terminal, so a great amount of resources such as metal, pipelines, plastics and the like can be saved, the cost for entering a residential district and the cost of the user can be effectively reduced, and the composite optic-fiber low-voltage cable is a final-mile access solution with the highest cost performance at present.
Description
Technical field:
The utility model relates generally to field of cables, relates in particular to a kind of Optical Fiber Composite low-voltage cable.
Background technology:
Optical fiber is fibre-optic writing a Chinese character in simplified form, be a kind of utilize light in the fiber that glass or plastics are made total reflection principle and the light conduction instrument reached.Optical fiber is invented by the preceding principal Gao Kun of Hong Kong Chinese University.Fine optical fiber is encapsulated in the plastic sheath, makes that it can be crooked and be unlikely to fracture.Optical fiber communication at a high speed, reliable and stable, antijamming capability is strong, has become inundant development trend.
Lv power cable is meant each or a plurality of conductor outer wrap one deck annular insulating barrier, and the electric wire in conductor and the shared same axle center of insulating barrier, whole then cable is encased by the sheath of polyvinyl chloride or other materials.Carry out the conduction instrument of electric energy transmitting.
How optical fiber and lv power cable are combined as a whole, become the direction of people's research.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of Optical Fiber Composite low-voltage cable to be provided, and it has the ability of electric power transfer and optical communication transmission simultaneously.
The utility model is achieved through the following technical solutions:
The Optical Fiber Composite low-voltage cable, include the conductor of some bunchys, each conductor is coated with insulating barrier outward respectively, the conductor of bunchy is coated with separator, armour and cable cover(ing) outward successively, it is characterized in that: be compounded with optical fiber in the space between described conductor and conductor, be filled with inserts between described conductor and conductor and between conductor and optical fiber.
Described Optical Fiber Composite low-voltage cable is characterized in that: described optical fiber includes fibre core, and fibre core is coated with optical fiber jacket.
The utility model is a kind of internal voids that utilizes lv power cable, and Optical Fiber Composite is made the cable that wherein has electric power transfer and optical communication transmittability.
Adopt the utility model in the communication access net, optical fiber with the low-voltage power wire routing, is implemented to and shows the family.Realize the height integral fusion of " flow of power, information flow, Business Stream ", have the modern power network of strong reliable, economical and efficient, clean environment firendly, transparent opening and friendly interactive intension.Rely on power optical fiber to the family network, can realize intelligent grid core business such as power distribution automation, power information collection, the service of intelligent power two-way interactive, and along with the variation of scientific and technological progress and social need for electricity, development wired home, intelligent building, intelligent residential district, intelligent city, integrated information service etc. are activated business.
One of important cable products during the utility model is built as intelligent grid, it has merged the function of communication and electric power, the many nets that can effectively realize telecommunications network, electric transmission network, television network, the Internet etc. merge, reducing the cost of networking, is one of present cost performance the highest " many nets merge " product.
The utility model product can be divided into two kinds.Rated voltage 0.6/1KV and following distribution are mainly used in distribution branches such as intelligent residential district or office building with optical fiber composite cable product, insert light-electric coupling box by pipeline, tunnel or direct-burried etc.Rated voltage 300/500V and following registering one's residence then are mainly used in user's access with the optical fiber composite cable, can horizontal or vertically connect up, and introduce intelligent electric meter and optical device terminal.
The characteristics of the utility model maximum are the functions that has merged optical fiber communication and electric power transfer, compare the simple function transmission cable, and 5 characteristics are arranged.
At first, light harvesting fibre and power transmission and distribution cable are, power optical fiber can make up the high-speed communicating network platform that covers the resident when laying power cable to the family, take all factors into consideration factors such as equipment, construction, conduit resource, adopt OPLC to compare with cable with laying optical cable respectively, can reducing the construction costs by a relatively large margin, the wasting of resources of also having avoided the secondary construction to cause is the present integrated level height of low pressure communication access net, save the optimization technique of resource.
Secondly, be applicable to the multiple business type, adaptability is strong, and autgmentability is strong, and product adaptation is wide.Use the Optical Fiber Composite low-voltage cable, cooperate corresponding apparatus and device, the many nets that can effectively realize telecommunications network, electric transmission network, television network, the Internet etc. merge, reduce the cost of networking, can on a transmission line, realize multiple business, as the Internet access, mediaphone, voice communication, business such as home intelligent ammeter, wired home, intelligent building, intelligent residential district, intelligent city.
The 3rd, possess stronger mechanical performance, as shock resistance and good anti-pressure measurement performance, adaptive capacity to environment is strong.We during this product, fully take into account the complexity of the environment for use of product in research and development, the Optical Fiber Composite low-voltage cable of smooth and prosperous research and development according to E1, E3, E4 among the GB/T7424 stretch, flatten, test such as impact, all meet and be better than the requirement of standard.
The 4th, green and security performance are superior.Consider that mainly the Optical Fiber Composite low-voltage cable is used for the user and inserts, we incorporate halogen-free flameproof, characteristic thinking such as fire-resistant in product design, have used the material of environmental protection, based on the consideration of safety, use fire-retardant, refractory material.The Optical Fiber Composite low-voltage cable meets the requirement of GB/T18380.3, GB/T19216.21, GB/T17650, GB/T17651.2 etc. fully.
At last, the light unit is compatible mutually with power cable long-term work temperature.After considering that the Optical Fiber Composite low-voltage cable lays, service life is longer, and light unit and power cable long-term work temperature compatibility mutually are very important problems.We are according to method F1 experiment among the GB/T7424, and every optical property index meets the YD/T629 requirement, and every electric property meets the requirement of GB/T12706.1, GB/T5023 and JB/8734.
The utility model has the advantages that:
The utility model light harvesting fibre and power transmission and distribution cable are avoided the secondary wiring, can effectively reduce expenses such as construction, networking.Using the Optical Fiber Composite low-voltage cable to go into scheme as intelligent grid user termination, save resources such as a large amount of metals, pipeline, plastics, can effectively reduce the every cost that enters sub-district and user, is present cost performance the highest " last kilometer " access scheme.
