Product advantage

Good insulation, good heat resistance, low price, rich experience in operation, low cost and so on.

Suspension porcelain insulators are made of porcelain, iron caps and steel feet with Portland cement and quartz sand glue. The surface of the porcelain parts is usually painted with white glaze and brown glaze, and other glazes can be painted as needed. The surface of the iron cap and steel feet are all hot-dip galvanized. The contact surface of the iron cap and the steel foot and the adhesive is thinly coated with a buffer layer, and the top of the steel foot has an elastic pad.

Stain-resistant insulators are divided according to their umbrella structure:

• Bell-type type: bell-type type stain-resistant suspension insulators use different periods of moisture in the umbrella and the suppression discharge of the high-edge under the umbrella, and the anti-fouling performance is better.
• Straw hat type: straw hat type stain-resistant suspension insulator has a large diameter, generally placed on the top of the hanging string, which has a good effect on preventing bird damage and penetrating icing.
• Double-layer umbrella type: double-layer umbrella stain-resistant insulator has large creepage distance, open umbrella type, smooth and non-ribbed inside and outside the skirt, low ash deposition rate, good self-cleaning performance
