A steel pipe pole that can realize the buried transmission line

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 intensive electricity load, the construction of high-voltage power lines using overhead bare wires or buried cables along the road is a relatively common construction method. In view of the advantages of low construction cost, large transmission capacity, and convenient operation and maintenance of overhead line methods, which cannot be replaced by buried cable methods, new high-voltage main power lines in cities or industrial parks must still be constructed with overhead bare conductors until the line is reserved. In the branch point, the overhead line is converted to the buried cable method, and the cable terminal head is required to use the cable terminal to convert the bare wire to the buried cable with an outer insulatin...

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
