Problems solved by technology

[0003] Electric poles made of ordinary concrete have the properties of light weight, low maintenance requirements, and good insulation, but the molding process is not only costly, but also has defects such as material shortage, irregular pores, warping deformation, and foaming during the production process. defect
The tensile strength and compressive strength of the formed utility poles are low, and they are prone to breakage in bad weather

Abstract

The invention belongs to the technical field of electric materials, and discloses an insulation electric pole. The insulation electric pole is made through the following steps: 1, preparing a material A; 2, preparing a material B; 3, preparing a material C; 4, preparing concrete; and 5, molding, and demolding. The electric pole has good freeze thaw resistance, good compressive strength and good rupture strength.

Description

technical field [0001] The invention belongs to the technical field of electric power materials, and in particular relates to an insulated utility pole. Background technique [0002] The utility poles used in traditional overhead transmission lines generally have defects such as heavy weight, perishability, and poor durability. They have a short lifespan, require frequent maintenance during operation, and are prone to various safety hazards. For example, steel poles and iron towers also have problems such as corrosion and rust, construction, transportation and maintenance difficulties. For ultra-high voltage and ultra-high voltage power transmission, because the self-weight of steel poles and iron towers exceeds the strength limit, the height of the tower cannot be raised. In the annual transmission line tripping accidents, lightning strike accidents and pollution flashover accidents account for almost half each. Extensive use of composite insulators still cannot completely...
