OM.R966 GIS Bus Expansion Joint Deformation Online Monitoring System

Product Overview
The busbar is a critical component of GIS, and the expansion joint—a subsidiary device of the busbar—plays a fundamental role in compensating for length adjustments during GIS installation, as well as accommodating thermal expansion and contraction of the busbar sections caused by seasonal and environmental temperature fluctuations during operation. Since the length of the GIS busbar changes with ambient temperature, if the expansion joint fails to function properly due to installation or manufacturing defects, it may lead to deformation and gas leakage at connection points under expansion stress, potentially resulting in severe insulation breakdown of the equipment. Therefore, real-time monitoring of the expansion joint's condition provides essential assurance for the daily maintenance and operation of GIS equipment.
