Working principle of composite insulator crimping technology
- Dec 21, 2018 -

Composite insulator mandrel and end metal accessories is a major part of the mechanical load, the connection between them is done by the interference fit after pressure, essentially is the hardware plastic material and brittle material of epoxy glass fiber core rod through the static friction force produced by crimping after formation of the interference fit of a solid components. The concrete process is as follows: the metal tool of the cylindrical inner cavity is placed on the mandrel, and certain pressure is exerted on the outer circumference of the mandrel by the multi-pressure equipment, so as to make the metal tool plastic-change the socket of the mandrel end, so as to achieve the purpose of connecting the mandrel with the metal tool.
