Lightning arrester bending tensile testing machine

Huayan's microcomputer-controlled arrester bending tensile testing machine is mainly used to test the mechanical properties of arresters such as tension, compression, and bending.The bending and tensile performance test of the arrester can be completed by configuring special arrester bending and tensile auxiliary equipment. It is mainly used for bending strength testing of various types of arresters such as zinc oxide arresters, valve-type arresters, and tube-type arresters.The system adopts microcomputer closed-loop control, has a wide and accurate loading speed and force measurement range, and has high accuracy and sensitivity for the measurement and control of load and displacement.This equipment is applicable to experimental standards such as GB/T11032-2016 "AC Gapless Metal Oxide Lightning Arrester", JB-T 8952-2018 "Composite Jacketed Gapless Metal Oxide Lightning Arrester for AC Systems" and GB 11032-2016 "Metal Zinc Oxide Lightning Arrester".
