固封极柱40.5kV

环氧固封极柱（又称固封式真空灭弧室）是在真空开关管外面包一缓冲材料然后再包一层环氧树脂。它取代了原来断路器上的绝缘支撑和机械支撑，大大减少了断路器的零件和体积，实现了集成模块化，易安装、免维护、体积小、耐压更稳定和可靠。旭光牌固封极柱采用环氧树脂自动压力凝胶成型工艺（APG工艺）将真空灭弧室和上、下出线座等载流元件封装成一个整体。由于选用性能优异的环氧树脂，保证了产品的机械、电气和耐热老化等性能，具有真空密封性能好、绝缘性能可靠、耐高低温冲击和机械冲击性能好、免维护、小型化、易安装等优点。

主要技术参数：额定电压：12KV~40.5KV ；额定电流：630A~4000A; 额定短路开断电流：16~50KA。产品符合或超过GB1984-2003以及IEC62271-100中E2级的要求。
