12kV Vacuum interrupter sealed pole embedded poles for outdoor circuit breaker

• As the vacuum interrupters of embedded pole are embedded in the epoxy resin, so their appearance are not affected by the external environment, the external insulation ability can avoid the effect from the dust, humidity,small animals, condensation,dirty, even though in the humid and heavy pollution condition, the vacuum interrupters can keep high impedance to voltage effect. Can totally satisfy the requirements at the second grade pollution with the GB/DL standard.
• 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 maxi-mize 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.
