CHANGZHOU, China, Oct. 21, 2026 /PRNewswire/ — October 15–16 saw State Grid Changzhou
Power Supply Company launch autumn maintenance work at Maoshan Scenic Area Substation
in Jintan and Wuyi Substation, including transformer capacity expansion installation
and routine autumn inspections of main transformers. The scheduled work lays a solid
foundation for the safe and stable operation of the regional power grid during the
winter peak power demand period.

Main grid substations serve as pivotal hubs for regional power supply. Leveraging
the window of relatively moderate power load, this round of autumn inspections focuses
on overhauling and calibrating main transformers and their protection and control
circuits within the service area. Maintenance for auxiliary systems covering fire
protection, communications and DC power supplies is carried out concurrently.

On October 15, the oil conservator of the transformer at Maoshan Scenic Area Substation
was hoisted into place to support the main transformer capacity expansion project,
which will boost power supply capacity during peak tourist seasons at the scenic
site. The following day, equipment inspection and circuit calibration proceeded 
in an orderly manner at Wuyi Substation. In recent days, Yangang, Xigang and Longshan
substations have also taken advantage of scheduled power outages to complete maintenance
of fire-fighting equipment, communication device upkeep, electricity meter replacement
and wiring adjustment for auxiliary power supplies, steadily finishing all inspection
and defect elimination tasks.

A core objective of the autumn inspection campaign is to identify hidden equipment
faults that are difficult to detect amid heavy summer loads, facilitate prompt rectification
of defects and improve the overall health of substation assets. The combined approach
of centralized overhaul and targeted special remediation will place grid equipment
in a more dependable condition to cope with rising winter electricity consumption.

Moving forward, State Grid Changzhou Power Supply Company will press ahead with 
remaining autumn inspection assignments, track the rectification of identified defects
and adjust operation and maintenance plans in response to load fluctuations. These
efforts will ensure all grid equipment enters the winter operating cycle in sound
condition.
