1116mm creepage distance porcelain line post insulator,line post type insulators

1116mm creepage distance porcelain line post insulator is one of porcelain line post insulator or line post type insulators and is usually composed of porcelain parts and spindle.

1116mm creepage distance porcelain line post insulator:
1116mm creepage distance line post type insulators are made up of porcelain unit, iron cap, steel pin. The iron cap and steel pin are assembled with porcelain part with cement. The cap and pin should be on the same axial line and don’t have obvious deflection. Pin insulator is one of porcelain parts or several parts assembled together with cement, and some of the insulator thread will use zinc sleeve, which is also cemented.

1116mm creepage distance porcelain line post insulator properties:
1116mm creepage distance porcelain line post insulators are typically used on high tension power distribution towers. Porcelain is by far the most commonly used insulating material but there are a number of composite styles as well. Line post type insulators revolutionized the power distribution industry allowing much higher voltage protection.
