|High Voltage Circuit Breakers
|Normal Type Circuit Breaker
• The vacuum interrupter is encapsulated in epoxy resin, which can be optimally protected from moisture,dust and external damage and suitable for different climatic consitions and high altitue of site.
• Epoxy resin with high glass transition temperature and high cracking resistance ensures the product with good mechanical strength and insulation properties under extreme conditions.
• Between the vacuum interrupter and the epoxy resin, there is LIM silicone rubber buffer layer with high mechanical properties and high pressure resistant, to reduce the internal stress, and maximize thermal and cold impact resistance.
• The design test of -55°C×48h ultra-low temperature freezing test has passed, without any damage to the mechanical properties and insulation properties of the product.
