金具热镀锌处理，提升防腐性能。端头采用迷宫式设计原理，多层保护，密封性能好。金具与芯棒的连接采用国际上最先进的电脑控制同轴恒压压接工艺，并配有全自动声发射探伤检测系统，保证了金具与芯棒的连接的可靠性与稳定性。芯棒采用ERC高温耐酸棒，芯棒与硅橡胶界面涂有特种偶联剂。伞套采用全自动硅橡胶注射成型机，在高温高压下一次性整体成型工艺。保证了硅橡胶与芯棒的结合力以及端部附件的密封性，解决了绝缘子最关键的问题 ---- 界面电气击穿。
The hot-dip galvanizing treatment of fittings can improve the corrosion resistance. The end adopts labyrinth design principle, multi-layer protection and good sealing performance. The connection between fittings and mandrels adopts the most advanced computer-controlled coaxial constant pressure crimping technology in the world, and is equipped with a full-automatic acoustic emission flaw detection system to ensure the reliability and stability of the connection between fittings and mandrels. ERC high temperature acid resistant rod is used as the core rod, and special coupling agent is coated on the interface between the core rod and silicone rubber. The umbrella cover adopts the full-automatic silicone rubber injection molding machine and the one-time overall molding process under high temperature and pressure. It ensures the binding force of silicone rubber and mandrel and the sealing of end accessories, and solves the most critical problem of insulator - interface electrical breakdown.
