Using the new crimping technology of metal end fitting Zn layer protection,making the indentation galvanized layer of metal end fitting not be wrecked (not turn black) in high strengh pressure crimping, extending the working life of metal end fitting,improving the quality of product greatly.
Firstly adopt metal end fitting and rod which can endure high temperature and have high acid resistance,and use sound wave emitter for supervising and control of fitting crimping,then once complete the whole high temperature injecting moulding (sealed).
Injection sealing technology
The end of composite insulator is sealed with high temperature vulcanized silicone rubber,A high temperature and high pressure injection molding process is adopted,the fluid xealant vulcanized molding with sheds and housing during the same injection molding operation in the mound,all the space between rod and end fitting are tilled.The incipient fault and defect which caused by other sealing technology are eradicated thoroughly,The reliability in the end seal is increased dramatically, this is an intemational leading technology.
