Long Rod Suspension Tension Composite Insulator

Product Description

Composite Suspension Insulator

Composite suspension insulators: silicone rubber canopies, designed according to aerodynamic principles, with integral moulding to ensure the effectiveness of the total creepage distance in all climatic and harsh conditions and to improve the drainage of the insulators; fibre rods made of ECR high temperature and acid resistant material; end joint connections with zinc cover protection, ultrasonic monitoring and computer controlled coaxial constant pressure, beautiful appearance and high quality. Different metal end joints shown, suspension insulators, long pole insulators, polymer insulators, cap and pin insulators, isolator insulators. Different colours shown, insulator manufacturers, hollow insulators, power line insulators, power line insulators, polymer pillar and suspension insulators.

Features of our composite insulators

1) Silicone rubber for the shed
2) Glass fibre reinforced epoxy resin rods for core (ECR type)
