Description

Hybrid Power Pole

The present invention relates to a hybrid electric pole, and more particularly, to a safe and economical hybrid electric pole that is spaced apart from an adjacent structure and does not interfere with each other.

In general, a pole is installed at the edge of a road or an alley of a housing complex, and is used to transmit power or communication signals by installing facilities such as a power cable or communication cable on the top of the pole.

Therefore, the upper part of the electric pole is kept in close contact with the communication pole or the wall of the building, and when installing related facilities such as cables on the upper part of the electric pole, it may interfere with other attachments such as adjacent electric poles or building walls and signboards. Having difficulty installing

To solve this problem, curved steel pipe poles have been developed and are in use, but the material cost is high due to the steel material and has the disadvantage that the price is almost 4 times higher than that of general poles.
