Steel pipe pole enabling electro-transmission lead to be buried

Abstract

The invention discloses a steel pipe pole enabling an electro-transmission lead to be buried. The steel pipe pole comprises a main pole as well as a ground wire crossarm and a plurality of transit crossarms, which are fixedly mounted on the main pole; the transmit corssarms are arranged in the axial direction of the main pole from the top down at intervals; a cable terminal head and a plurality of crossarm insulators are correspondingly arranged at the lower part of each transmit crossarm; the crossarm insulators are arranged above the cable terminal heads, and are fixedly connected to the main pole; the cable terminal heads are arranged at the bottom of the main pole, and take a plane which is perpendicular to the main pole as a reference surface; and the projections of the different crossarms are mutually staggered on the reference surface. The steel pipe pole is small in occupied space, and can concisely and smoothly lead the electro-transmission lead into the ground in a smaller space, so that the steel pipe pole can be installed and constructed on a greening road in the center of the road or on a sidewalk.

Description

technical field [0001] The invention relates to a steel pipe pole in the field of power transmission, in particular to a steel pipe pole capable of realizing the buried power transmission wire. Background technique [0002] In cities or industrial parks with dense electricity loads, the construction of high-voltage power lines using overhead bare wires or buried cables along roads reserved for green belts or sidewalks is a relatively common construction method at present. In view of the advantages of low construction cost, large transmission capacity, and convenient operation and maintenance, the overhead line method cannot be replaced by the buried cable method. New high-voltage main power lines in cities or industrial parks must still be constructed with overhead bare conductors until the line is reserved. Then convert the overhead line to the buried cable at the branch point, and use the cable terminal head to convert from the bare wire to the buried cable with the outer ...

AI Technical Summary

Problems solved by technology

This method requires the use of cable terminal angle steel towers, and the construction of a bearing platform along the outer edge of the angle steel tower body, which occupies a larger area than ordinary angle steel towers, and cannot lead the transmission wires to the ground concisely and smoothly in a small space. It is impossible to build green belts or sidewalks in the center of the road
