FPQ2W-10/3T20 10kV Pin Insulators

The crimping process of polymer pin type insulators should pay attention to the crimping force, compression amount, pressing speed, holding time, etc. during crimping. Due to the cumulative error of the size of mandrel and fittings, the maximum error can reach 0.2mm. According to experience, a compression error of 0.05 mm may cause an error of more than 10% on the crimping strength. Therefore, the crimping process will focus on pressure, and determine the proper The crimping force; in order to reduce the influence of the mandrel and the material fluctuation of the fittings, it is assisted to control the amount of compression; the pressing speed should not be fast, and the fittings should be fully plastically deformed during the slow pressing process, and the holding time should not be too long , to prevent the mandrel from breaking, the best experience time is about 2s.
