At the same time, the operation and maintenance personnel strictly implement the anti-freezing measures of the water supply system in the substation, strengthen the operation inspection of fire water pipes, water tanks, water pumps, etc., and deal with problems immediately. Thermal insulation and antifreeze wrapping of some key pipelines to avoid pipeline rupture.
