Core Performance Advantages

Lightweight & Easy Installation

Weighing significantly less than equivalent porcelain insulators, our 12kV composite long rod insulators simplify transportation and installation processes. Their compact design reduces the load on transmission towers, allowing for more efficient tower design and lower overall project costs.

Enhanced Anti-Pollution Performance

The silicone rubber housing exhibits excellent hydrophobic properties, preventing water film formation and reducing the risk of flashovers in polluted environments. This makes our insulators ideal for use in urban areas, industrial zones, and agricultural regions with varying levels of air pollution.

Vibration & Moisture Resistance

These composite long insulators feature excellent anti-vibration capabilities, ensuring stable performance even in areas with high wind speeds or seismic activity. The integrated high-temperature vulcanized silicone rubber sealing system provides superior moisture resistance, protecting the internal fiberglass core from degradation.
