The optical fiber composite low-voltage power cable of the invention is simple in structure, excellent and scientific in material selection, excellent in product performance and favorable in environment protection performance so that the establishment requirement of national intelligent grids can be satisfied; the communication function and the power function are converged so that multi-network convergence can be effectively realized; and the optical fiber and the power output and distribution cable are integrated and secondary wiring is avoided so that the cost for construction, network construction and the like are effectively reduced.
Description
Technical field
The present invention relates to a kind of Optical Fiber Composite lv power cable that is applied to intelligent grid, belong to the cable technology field.
Background technology
Along with national grid and south electric network strengthen construction to intelligent grid, except backbone network is built high pressure, superhigh pressure large capacity transmission circuit energetically, also try hard to recommend power optical fiber to the family (PFTTH) at user side.Power optical fiber is meant to the family, in the low pressure communication access net, adopt the Optical Fiber Composite low-voltage cable, 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.
In July, 2010, State Grid Corporation of China announces incision " integration of three networks ", and by intelligent grid engineerings such as enforcement power optical fibers, will use electrical network and telecommunications network, broadcasting and television network, the Internet etc. to organically blend.State Grid Corporation of China now in its scope 20 of 14 provinces cities begin the power optical fiber pilot construction of registering one's residence." adopt the Optical Fiber Composite low-voltage cable to realize that power optical fiber is to 36700 families, family (PFTTH); After the pilot success, large tracts of land is promoted, the electric power of newly-built sub-district inserts from now on, all will adopt power optical fiber to register one's residence." south electric network also will take similar mode to carry out power optical fiber to the family.According to 50M use amount calculating per family, calculate that thus the pilot demand was greatly about about 1800 kms in 2010.By 2011, after the power optical fiber of intelligent grid finishes to family (PFTTH) pilot, power grid enterprises will progressively promote the use of, and except newly-built dwelling house, add the transformation of original sub-district, top, expect 2015, and demand will be above 200,000 kms.
The intelligent grid construction has proposed new requirement to traditional optical cable and electric power transfer, and the Optical Fiber Composite low-voltage cable is as the staple product of user's incoming end in the intelligent grid construction, light harvesting fiber communication and electric power transfer are in one, satisfy intelligent grid informationization, automation, interactive demand, have stronger advantage and application more widely, will provide safe and reliable guarantee for the intelligent grid construction.
The Optical Fiber Composite low-voltage cable can realize that it is intelligent grid cable main force that many nets merge.One of important cable products during the Optical Fiber Composite low-voltage cable 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.
We are according to national intelligent grid construction demand, researched and developed the compound low-voltage cable of a kind of novel optical fiber, can realize the unified fusion of electric power transfer and optical communication transmission, light harvesting fibre and power transmission and distribution cable are, avoid the secondary wiring, can effectively reduce expenses such as construction, networking.
Summary of the invention
Technical problem to be solved by this invention is in order to satisfy novel four net fusion demands, to provide a kind of environment-friendly optical fiber compound lv power cable.
