Description

Insulation rack for distribution line processing

The present invention relates to a rack, and more particularly, to an insulation rack for power distribution processing for attaching a power distribution line made of an insulating material and integrally manufactured by reducing the number of parts to a pole.

In general, in order to supply electric power to the receiving station in the overhead power distribution line of the power system, a low voltage pole is installed, and the lead wire is drawn out from the low voltage line to be connected to the receiving station.

The low-voltage wire is attached to the insulator's groove in the pole, and it is tied with a bind wire to extend the fixed wire to the periphery of the receiver, and is connected to the receiver through a separate lead wire.

At this time, the member for fixing the low-voltage wire to the pole is called a rack (rack), the conventional rack has a complicated structure to connect a separate strap wound around the low-pressure insulator is mounted or directly wound around the wire to bind with a bind wire.

Working with these conventional racks not only takes a lot of work time due to cumbersome processes, but also requires a lot of material because it assembles arm tie, rack bands, racks, insulators, straps, bind wires, clamps, etc. There are problems such as complicated facilities and impairs the aesthetics of the pole.

In particular, the conventional rack is required to insulate in order to prevent a short with the distribution line or the lead, this is because the material must be installed, such as insulators or straps, there is a problem that the related costs increase.

Due to these problems, insulation racks that do not use insulators have been improved and provided, but they are not used in the field due to mechanical strength or difficulty in installation.
