Use and structure of suspension porcelain insulator
- Feb 07, 2018 -

Introduction of purpose, structure and model:

High voltage line type suspension porcelain insulator (common type) is used for insulation and fixed conductors in high voltage overhead transmission and distribution lines, and is normally assembled into insulator strings for different voltage grade lines.

The common type insulator is suitable for the general area. If the number of insulators can be increased appropriately, the pollution flashover performance can be improved.

The suspension porcelain insulator is made of porcelain, iron cap and steel foot with no less than 525 silicate cement and quartz sand cement. Iron cap and steel foot with adhesive contact surface thin coating a layer of buffer, steel foot top with elastic gasket. The surface of porcelain is usually painted white glaze and brown glaze, and other glaze can be painted as needed. Iron cap, steel foot surface all hot zinc. The push-pull type elastic locking pin of ball type connection has both W and R type, which are made of tin bronze, brass and austenitic stainless steel, which is flexible and anticorrosive, and easy to disassemble and assemble. The cylindrical and hump of the grooved joint are used for the surface heat of zinc, which is made of brass. The above elastic locking pin, cylindrical pin and other parts are in complete supply with the product.

Insulators are divided into two types: ball type and groove type.

Common type and dirt resistant insulators of the same strength grade, with the same ball and socket joint dimensions, can be guaranteed to be interchangeable.
