Description
1. Product Overview
2. Product Structure & Anti-Corrosion Design
- Porcelain inner core
Solid porcelain core delivers steady insulation performance. It resists electric breakdown and keeps stable under long-term voltage load.
- Outer silicone rubber shed
We cover the core with weather-resistant silicone rubber. It holds lasting water repellency to stop pollution flashover in dirty areas. It fights UV and aging outdoors.
- Full anti-corrosion coated metal fittings
We spray a thick anti-corrosion coating on all upper and lower metal hardware. The coating sticks tightly to alloy surfaces. It stops salt water, acid gas and damp air from corroding metal parts. It extends the whole insulator’s service life greatly.
3. Key Advantages
- Dual reliable insulation performance
Porcelain core provides solid basic insulation. Silicone rubber sheds strengthen anti-pollution ability. The two layers work together to avoid leakage and flashover faults.
- Powerful long-term anti-rust protection
The integrated anti-corrosion coating covers every metal surface without dead angles. It adapts to coastal salt fog, chemical plant waste gas and humid mountain areas. It avoids frequent replacement caused by rusted fittings.
- Balanced weight & high mechanical strength
It is lighter than full porcelain insulators and stronger than simple rubber composite types. It bears strong bending load and stays stable under wind vibration. Single staff can finish installation quickly.
- Low maintenance cost for power grids
Anti-corrosion coating reduces metal failure rate. Silicone rubber needs no regular cleaning. Power teams cut inspection and repair work year by year.
- Universal installation size
We keep standard mounting threads same as traditional pin insulators. You do not modify poles or clamps during replacement. We support custom coating thickness for extra corrosive sites.
