Problems solved by technology

Cable ties are easy to age when used outdoors, and the wires are easy to corrode and rust (galvanized steel wire and stainless steel straps will not rust), and direct contact between metal straps and OPGW optical cables is prone to inductive effects. When the OPGW optical cable has too much induction When the metal cable tie will produce galvanic discharge

Abstract

The invention discloses a transformer substation cable-splitting type OPGW redundant cable rack. The transformer substation cable-splitting type OPGW redundant cable rack comprises a cable rack mounting frame (7), wherein the back of the cable rack mounting frame is mounted on a cable pole through cable pole hoops (10); at least four opening type insulation redundant cable forks (1) are mounted onthe front of the cable rack mounting frame; an OPGW optical cable locking bolt (2) and an ordinary optical cable locking bolt (3) are oppositely arranged in an opening of each opening type insulationredundant cable fork so as to form an outer coiling opening used for storing a redundant OPGW optical cable (4) in coils and an inner coiling opening used for storing an ordinary optical cable in coils; a high-voltage isolation switch (6) is mounted on the cable rack mounting frame; a connector box mounting insulation plate (9) is mounted on the cable rack mounting frame; and an OPGW connector box (8) is mounted on the connector box mounting insulation plate (9). The transformer substation cable-splitting type OPGW redundant cable rack is capable of effectively eliminating the inductance effect of the previous metal redundant cable rack; the OPGW optical cable is safer and more reliable in operation.

Description

technical field [0001] The invention relates to the technical field of power cable installation, in particular to a substation cable splitting type OPGW residual cable rack. Background technique [0002] At present, some power company substation OPGW downduct cable residual cable racks are made of metal or non-metallic materials. Before the residual cable racks are installed, rubber pads are used to separate the residual cable racks from the portal frame to maintain the residual cable racks and the portal frame. "Reliable insulation" between the frameworks, the redundant OPGW optical cable and the ordinary optical cable reel are stored together, and the reeled optical cables are bound with cable ties or iron wires to maintain the appearance consistency. The insulation of the metal residual cable rack and the door frame is unreliable with rubber pads. The rubber will accelerate the aging of the rubber in the high-voltage environment. The life of the rubber pad in the high-vol...
