railway composite insulation features
- Offers good electrical and mechanical performance for safe power transmission.
- Handles heavy pollution well. Its pollution flashover voltage is 2-3 times higher than porcelain insulators.
- The silicone rubber has special water-repelling properties. Even with dirt, it keeps high performance, making it great for hard-to-reach places.
- Weighs 1/7 to 1/10 of porcelain insulator strings, making it easy to transport and install. Perfect for remote areas or fast repairs.
- The shed has great waterproof and aging resistance for long-term use.
- Can handle impact and vibration, ensuring reliable operation.
