| 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
