Wholesales Composite Polymer Insulator /polymer insulators wholesalersWe offer an deal in wide range of Light Weight Polymer Disc Insulator 10kv-500kv series composite insulators, also known as polymer insulators or silicon rubber insulators, which include suspension long rod silicone rubber insulators, pin type composite insulators, station post polymer insulators, cross arm silicone rubber insulators, electrified railway polymer insulators, Polymer disc insulator, polymer lighting arrester.
As the replacement of porcelain insulators, silicon rubber composite insulators have many advantages:
1. Excellent anti-pollution performance, suitable for high polluted area
2. Free of cleaning, economical maintenance and suitable for difficult maintenance area
3. No need of zero value check
4. Light weight, easy and economical to transportation and installation
5. Not brittle, and reduce the purchasing quantities for spare parts.
