Description

Overhead line high voltage tower pole

technical field

The utility model relates to a tower rod for electric power, in particular to a high-voltage tower rod for overhead lines.

Background technique

At present, most domestic 10KV overhead line tower poles adopt the general electrical installation standard of the whole picture. During the wiring process, due to the problems of the tower pole structure and the wiring method, there are problems such as construction troubles, waste of materials, and low distance between the conductors of the same pole height and the ground. shortcoming.

For this reason, people are seeking a kind of technical solution suitable for practicality always.

Contents of the invention

Aiming at the deficiencies of the prior art, the utility model provides an overhead line high-voltage tower rod with ingenious conception, simple structure, strong practicability, convenient construction and material saving.

The technical scheme adopted in the utility model is as follows:

A high-voltage tower pole for overhead lines, including a tower pole and a cross arm, at least one set of circuit cross arms is arranged on the tower pole, and each set of circuit cross arms includes three cross arms, and each of the cross arms A set of main line wiring insulator strings and a set of branch line wiring insulator strings are provided respectively.

Based on the above, the cross arm is located between the direction in which the main line connection insulator series is connected to the main line and the direction in which the branch line connection insulator series is connected to the branch line.

Compared with the prior art, the utility model has substantive characteristics and progress. Specifically, the high-voltage tower pole breaks through the wiring structure of the traditional tower pole, and then changes the traditional wiring mode, so that the tower pole has ingenious conception, simple structure, It has the advantages of strong practicability, material saving, convenient construction, increased wire-to-ground distance with the same pole height, and convenient post-operation management.
