Porcelain disc insulator intrudction:
Porcelain disc insulator is one main type of porcelain insulator and used for power transmission line and distribution line.Disc suspension insulator is generally made of insulating porcelain body and metal accessories which cemented with insulating part.
Porcelain disc Insulator used to support and hand wire and insulate wires against tower.This type insulator normally includes ball and socket type, clevis and tongue type.Disc insulator can be assembled together and come into insulator string suitable for any voltage class requirement.
Types of porcelain disc insulator:
1.Normal type: Disc insulator with ball and socket or clevis and tongue connection or slot conntection.
2.Fog Type: Disc insulator has a long underside of the umbrella to keep the inner part from moist.
3.Anti pollution type: Disc insulator with double shed. which has large creepage distance that can be used in high pollution area.
