Application Study For Electric Special Type Fiber Cable

With the progress of information technology, Electric system communication has more attraction to the whole society by its special developing advantages. In course of constructing for electric optical fiber cable net, electric special fiber cable makes a important role.This article on basic of anatomizing the structure characteristic of ADSS cable, analyzes the using quantities calculation formula of fiber excess length and reinforcement-Kevlar , considers that slip-on pipe's twisted pitch is guarantee key for fiber excess length, and considers that the determination for using quantities of Kevlar is a cycling solution procedure, in another aspect, designing a Distributed Optical Fiber Temperature Sensor System for monitoring electric rot accident, and give out the accurate position for accident.This article on basic of analyzing the structure characteristic of OPGW cable, analyzing the mechanism of production of fiber excess length and the calculate formula of fiber cable permitted short-circuit current, only after finding the optimal prebias position ,we can guarantee the better high and low temperature character and tensile-strength of fiber cable; and reducing the actual short-circuit current is the critical factor for increasing fiber cable stability, on the other hand, this article summarizes that lightning stroke is the main reason which makes cable twisted off, when lightning stoke is discharging, the long discharge period current is principal reason that make cable twisted off, this article deem that the improvement of cable structure and materials is done, then OPGW cable the ability of proof-lightning stroke will be rised.
