Snowflake type OPGW over-cable rack

Abstract

The invention discloses a snowflake type OPGW over-cable rack which comprises a body and a sign board. The body comprises three strip-shaped bodies distributed in a 60-degree structure similar to a snowflake type with the middle as an intersection point. The sign board is arranged on one side face of the intersection point. Arc-shaped hooks are arranged on the front portions and the rear portions of the two ends of each strip-shaped body. Every two arc-shaped hooks are distributed in a back-to-back mode, hook openings are outward, and locking devices are arranged on the hook openings. The strip-shaped bodies on the two sides of the intersection point of each strip-shaped body are each provided with fixing holes. The snowflake type OPGW over-cable rack has the advantages that practicality is good, the over-cable rack is attractive and elegant, the insulating and fixing reliability degree of an OPGW can be enhanced, the OPGW is separated from a common cable, the OPGW and the common cable are not intersected or knotted, investment cost is low, popularization is easy, and application prospects are good.

Description

technical field [0001] The invention relates to a residual cable rack, in particular to a snowflake-type OPGW down-lead residual cable rack. Background technique [0002] With the extensive construction of intelligent substations and the reconstruction of old sites, communication optical cables have grown from scratch, and have been upgraded from ordinary cables to special power cables such as ADSS and OPGW. Nowadays, new substations usually use OPGW to enter the station along with high-voltage lines, which not only shortens the construction period and cost, but also reduces the difficulty of later operation and maintenance. OPGW enters the station along with the high-voltage power line, and must be led down and welded with ordinary optical cables before entering the communication station. During the lead-in process, OPGW residual cable racks are used to coil the remaining optical cables after welding. [0003] Existing OPGW remaining cable racks generally consist of two ho...

AI Technical Summary

Problems solved by technology

[0003] Existing OPGW remaining cable racks generally consist of two horizontal and vertical steel sheets intersecting to form a cross shape, which has many problems such as unreliable insulation, no optical cable signboard, and inconvenient construction. , the torsion, stress, and tension generated during twisting are relatively large, and the four-point cross fixing method is easy to loosen and fail, resulting in new hidden dangers: such as physical tension that causes the core of the optical cable to break, and the discharge of the OPGW optical cable after it is loose and the contact gap with the structure causes the optical cable to corrode, etc.

At the same time, in the traditional method, the OPGW and the remaining cables are mixed and fixed, and it is easy to cross and knot, and it is easy to sprain the optical cable during maintenance, and the coiling remains unchanged.
