Insulator Quality Inspection Project
Publish Time: Author: Site Editor Visit: 2
Strengthen quality inspections of suspension composite insulator, especially spot checks of newly purchased batches of composite suspension insulator, to ensure that every polymer suspension insulator meets technical standards and operating requirements. The power grid operates in a complex environment, with factors such as high voltage, humidity, and pollution affecting the insulation performance of suspension type insulator. If composite tension insulator testing procedures are relaxed, inferior products could easily enter the grid, posing safety risks and causing economic losses.
