Abstract

The invention discloses a manufacturing and processing technology for an electric stay insulator, and relates to the technical field of insulators. The technology comprises the following steps: weighing raw materials: Zuoyun soil, a bauxite / modified fumed silica composite material, granite powder, nano boron nitride, a mica powder coated modified nano calcium carbonate composite material, lamellar mica, a potassium titanate whisker coated lignin fiber and coconut fiber composite material, modified bentonite, a zinc oxide / silicone rubber composite material and a sintering aid. The process comprises: premixing the materials except a sintering aid to obtain a premix, putting the premix into a ball mill, and adding water for ball milling to obtain a mixture; sieving, removing iron, squeezing mud, aging, pugging in vacuum, forming, fettling and drying; pre-sintering; crushing the pre-sintered material; and pressing the crushed material and a sintering aid, and sintering a pressed part. The process has the beneficial effects that a prepared insulator has the advantages of high mechanical property, high strength and the like.

Description

technical field [0001] The invention relates to the field of insulators, in particular to a manufacturing and processing technology for electric cable insulators. Background technique [0002] Insulators are special insulation controls that can play an important role in overhead transmission lines. Insulators are mostly used on utility poles, and gradually developed into high-voltage wire connection towers where many disc-shaped insulators are hung at one end. It is used to increase the creepage distance, usually made of glass or ceramics, and is called an insulator. Insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to the ground. These two functions must be guaranteed. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions. Otherwise, the insulator will not play a significant role, and it will damage the service life ...
