Fabrication of High voltag insulators spindle pin
Spindle pin porcelain insulator is used for working frequency voltage of 6 ~ 20kV high voltage overhead power line, Spindle pin is used to insulate and support wire.The old type of insulator is rated at the rated voltage 184.108.40.206 kV, each of spindle pin is divided into two types of steel foot type, which is divided into iron and straight legs and wooden poles.The rated voltage of the new model is 10kV, the normal type, the reinforced insulation 1 type, the reinforced insulation 2 type 3 kinds.
USING OF IT
The insulator is made of ceramic parts, steel legs (or snails) with no less than 525 silicate cement and quartz sand cement, and the steel foot glue is pressed into the spindle pin parts to prevent the steel foot loose.Elastic pad between the top and the spindle pin parts of the steel foot.The surface of spindle pin is usually brown glaze or white glaze, steel feet are treated with hot galvanization.
