Method for preparing insulator

Abstract

The invention discloses a method for preparing an insulator. The method comprises the following steps of: a, preparing a three-dimensional framework which has a shape matched with that of the insulator by using a glass fiber bundle, wherein glass fiber cloth is coated on the surface of the framework and is soaked with epoxy resin; b, when the epoxy resin starts to solidify, uniformly coating resin containing ceramic powder or glass powder on the surface of the framework, and putting the framework into an insulator mold; and d, raising the temperature, sizing, solidifying and then demoulding to obtain the insulator. According to the integrated insulator prepared by the method, a process of sleeving umbrella skirts on core rods of the insulator sequentially one by one is eliminated, and labor power is saved; and the insulator prepared by the process has low dead weight, a high electrical property and a high mechanical property. Both a hollow insulator and a solid insulator which are prepared by the process have a high electrical property, a high mechanical property and low dead weight. The insulator is suitable for outdoor high-voltage power transmission lines.

AI Technical Summary

Benefits of technology

This technology allows us to create a 3D structure called bone from wires wrapped around a special material like paper instead of traditional methods such as weaving them into shapes. By doing this, there are fewer steps needed than making up conventional structures, saving time and reducing labor costs compared to current processes. Additionally, these materials have excellent electricity conductivity but they also provide better strength when used inside buildings due to their lower density relative to regular steel bars. These technical results allow for more efficient use of space while maintaining structural integrity during power line construction operations.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the design of composite posts insulator materials that can resist external environmental factors such as rainwater, snow loadings, impact from vehicles, strong winds, etc., while still maintaining their ability to handle these physical conditions without losing structural integrity over time due to crack formation caused by thermal stress cycles like those experienced when installing overhead wires underground at electric facilities.
