Product Description

70KN Porcelain Disc Suspension Insulator With Cap

 

Porcelain insulators have a wide field of application: contactors, disconnectors, transformers equipment, capacitors, grommets also with end surface, atypical insulators (filters). Characteristics of high plasticity during production, precision grinding possibilities, as well as carburizing and bonding with excellent mechanical properties allow a wide range of shapes to be created and used for any type of application.

 

Ecological. When it is time to remove them, porcelain insulators are not hazardous waste. They are made from natural materials through simple mixing and curing; they can be stored in landfills with other waste and, additionally, they can serve as recycled material to produce ceramics and other similar products.
