FNB Series Composite Insulator
Parameters:
- The silicone rubber sheds adopt overall injection pressure process, so solve the reliability of composite insulators problem of the interface electrical breakdown. The core and the metal fittings using the most advanced technology, high strength, good looks, small size, light weight, corrosion-resistant galvanized fittings, the product structure, reliable, does not damage the mandrel, give full play to its mechanical strength.
- Excellent electrical properties, high mechanical strength.
- Good stain resistance, and does not require cleaning, re-contamination can run to safety.
- Small volume, light weight. The structure is dexterous, convinient to transport and installation.
- Silicone rubber sheds with good hydrophobic properties, the overall structure ensures that the insulation does not get wet, no preventive insulation monitoring tests, no cleaning, reducing routine maintenance.
- Good sealing performance, good resistance to corrosion, with good resistance to aging, corrosion resistance, low temperature resistance, suitable for -40 °C ~ -50 °C areas.
- Has a strong impact resistance and shock resistance, good anti-fragility and creep resistance, unbreakable, anti-bend, high torsional strength ,can withstand internal pressure, explosion-proof is strong.
Application
The product is fit for the polluted area, especially the badly polluted area, it has high tensile strength, anti-polluted, convenient installation and use, using a variety of hardware connection structure, connected compact with the lines .
