2.Pin type composite insulator Characters

The silicone rubber sheds adopt overall injection pressure process, so solve the reliability of pin type composite insulatorproblem of the interface electrical breakdown. The pin type composite insulator 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. 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.
