[0002] The top of the substation's main transformer and accessories, such as large transformer radiators, are all over 2 meters high. Working on these parts falls under the category of high-altitude operations. According to power safety regulations, workers performing high-altitude operations must wear safety belts, and the safety belts must follow the principle of "hanging high and using low." That is, the high point of the safety belt should be hung higher than the worker's work position to provide optimal fall protection. However, due to the equipment characteristics and installation and construction requirements of the main transformer, it is often difficult to install safety barriers or scaffolding on its top and upper part for safety protection. As a result, when workers perform maintenance work, they have nowhere to hang the safety belts, or they are forced to adopt the "hanging low and using high" method.
