Functions
Composite Station post insulators have the advantages of anti-pollution flashover, high strength, light weight, anti-impact, easy for maintenance and project costs saving etc. The composite post insulators are widely applied to:
• Post-type circuit breaker
• Disconnector
• Electric reactor
• Converter valve
Advantages
• Excellent performance of hydrophobicity, anti-aging, anti-tracking, anti-erosion.
• High tension & bending strength, high mechanical strength, anti-impact, shake-proof and not fail easily for brittle.
• Light weight & small, convenient for installation, the dimensions can be customized, and interchangeable with porcelain post insulators.
• Don’t need to be manually cleaned, which make it safer.
• Application: post-type circuit-breaker, disconnector, current limiting reactor, paralleling resistor, converter valve and many other outer insulation posts of equipment.
