Porcelain line post insulator 69KV specifications:
Insulating material: The insulator body of the unit is made from high quality aluminum oxide porcelain, either C-130 (IEC 60672) or C-120 as per customer's request.
Glaze color: Brown or grey.
Cementing: Portland cement is also possible.
Smooth rounded contours of the shell provide protection against chipping.

Porcelain insulators are the traditional choice for distribution line, busbar and apparatus insulation. Horizontal porcelain line post insulators are manufactured from high quality non-porous electrical porcelain, they provide a long life and cost effective solution for the majority of applications. The glaze applied is compressive in nature and formulated to provide a smooth surface for self cleaning.

Porcelain line post insulator 69KV parameters:

Nominal voltage kv 69
Creeoage distance mm 1805
Cantilever strength kn 12.73
Low frequency withstand voltage dry: kv 250
Low frequency withstand voltage wet: kv 225
Lightning impulse withstand voltage: kv 350

All units are manufactured from high strength alumina porcelain and are smaller in diameter, lighter in weight and more resistant to impact damage than insulators manufactured from standard strength silica porcelain. Orient can offer horizontal ceramic line post insulators selection guide for each customer. For detailed information on our porcelain line post insulator 69KV, please contact Orient.
