Product Description

Production Process of Polymeric Deadend Insulator

Production Description

WORTAI polymeric insulators DS series are use for electrical power distribution suspension or dead end instalation, replacing the the conventional porcelain or glass chains. Polymeric insulators produced initially from a fiberglass rod (core) which is fixed to the metal fittings (clevis and tongue in special forged steel with hot-dip galvanized coating) and later then insulating envelope (in high quality silicone rubber) is applied on this set, resulting in a compact, light insulator of great mechanical resistence and highly resistant to weather conditions. The main advantage with the use of WORTAI DS series insulators are:
• The housing and sheds of the insulator are made of silicone rubber, one shot injection moulding; this ensures
that the interface between the rubber and rod is impenetrable against moisture ingress.
• The core rod of insulator is made of a fiberglass that has excellent electrical and mechanical strength.
• Leakage current surge suppression due to high level of hydrophobicity of silicone rubber.
• Better performance in polluted areas.
• Light weight for handling and installation.
• The silicone insulators are manufactured and tested according to the standards ANSI C29.13 and IEC 1109
