A method for arranging an "h" type cable terminal pole lead in a wide area of terrain

By using the "h"-shaped cable terminal pole arrangement method, the load of each phase conductor is distributed to different poles, which solves the problem of large load and large land occupation of cable terminal steel pipe poles in wide terrain areas, and achieves resource conservation and reduced construction costs.

AI Technical Summary

Technical Problem

In areas with wide terrain, the load and bending moment of cable terminal steel pipe poles are large, resulting in a large root diameter at the bottom of the steel pipe poles, which leads to a large permanent land occupation area, serious waste of resources, and high construction difficulty.

Method used

The "h"-shaped cable terminal pole arrangement method includes a vertically installed first pole, a second pole, a pole connecting beam, and ground wire crossarms, upper conductor crossarms, middle conductor crossarms, and lower conductor crossarms distributed from top to bottom at intervals. Each crossarm is installed vertically and symmetrically with the overhead conductors. The cable terminal platform is independently set on both sides of the pole. The load of each phase conductor is distributed to different poles, reducing the weight of the steel poles and the amount of reinforced concrete used in the foundation.

Benefits of technology

It effectively reduces the weight of steel poles and the amount of reinforced concrete used in the foundation, reduces the permanent land occupation area, lowers project costs and construction difficulty, and has significant economic and social benefits.

Abstract

The application discloses a kind of "h" type cable terminal pole lead arrangement method of wide area topography.It contains cable terminal pole cross arm arrangement, side standing type cable terminal platform arrangement and lead hanging line mode;Upper portion of cable terminal pole pole body is spaced distribution from top to bottom upper cross arm structure, middle cross arm structure and lower cross arm structure, cable terminal platform.Cable terminal pole is connected to cable terminal platform with cable through lead string at upper, middle and lower cross arm, and realizes cable lead down.The application not only can make overhead line connected lead current line maintain enough safety distance, but also can distribute load of each phase conductor to different pole body, effectively reduce weight of steel pole and square amount of reinforced concrete foundation, reduce permanent land area of steel pole, greatly reduce engineering cost and construction difficulty, with remarkable economic benefit and social benefit.
