真空灭弧室嵌入杆
环氧树脂固体密封极（又称固体密封型真空灭弧室）是在真空开关管外的缓冲材料，然后是一层环氧树脂。它取代了原有断路器的绝缘支撑和机械支撑，大大减少了断路器的零件和体积。具有体积小、压力更稳定可靠的优势，实现了模块一体化，安装更方便，免维护。
武汉飞特牌实心密封杆的环氧树脂自动加压凝胶成型工艺（APG工艺）真空电弧淬火室与上下出口座和载流元件封装成一个整体。由于采用了性能优良的环氧树脂材料，极大地保证了产品的机械、电气和热老化性能，嵌入式极具良好的真空密封性能。它可靠，具有良好的耐高低温冲击和抗机械冲击性能。它具有免维护、结构紧凑、易于安装的优点。环氧实心密封杆配套相应的室内外真空断路器或真空配电装置，特别配套频率为50Hz/60Hz，额定电压为12kV、17.5kV、24kV、27.5kV和40.5kV，适用于电力、机械、化工、冶金、矿山等部门运行工况频繁运行的场所。
