CHANGZHOU, China, July 23, 2026 /PRNewswire/ — State Grid Changzhou Power Supply
Company has completed an automated upgrade of pole-mounted switches on the 10kV 
Huangjia Line, rolling out a refined zero-perception construction model to secure
reliable power supply amid the peak summer electricity demand. The project benefited
over 400 households in Huangjiayuan Community in Jintan District with nearly uninterrupted
power service throughout the renovation, setting a replicable benchmark for grid
optimization and customer-centric power upgrades.

Built in the early years, Huangjiayuan Community faces mounting power supply challenges
as annual summer electricity consumption continues to surge. Aging pole-mounted 
switch equipment on the 10kV line has become a hidden hazard restricting local power
supply stability. To address the pain point fundamentally, State Grid Changzhou 
upgraded the outdated devices to intelligent automated switches equipped with real-
time fault detection and rapid isolation functions. The newly operational smart 
switches can instantly identify line faults and drastically cut power outage duration,
significantly elevating the overall reliability of regional power grid operation.

To eliminate construction disruptions to residents’ daily lives, the company adopted
a tailored construction strategy featuring **pre-power generation, live-line coordination
and phased operation**. A total of eight low-voltage generator vehicles were deployed
for collaborative power guarantee, while professional live-line operation teams 
disconnected high-voltage side leads without cutting off the main trunk line power
supply. Thanks to the refined and tech-enabled construction scheme, only a handful
of residents experienced an extremely brief power switching process, and the vast
majority of end users remained unaware of the ongoing grid renovation.

Since the start of 2026, State Grid Changzhou has vigorously promoted zero-perception
grid construction across its service areas. In Jintan District alone, the company
has completed more than 4,500 live-line power operations and generator-assisted 
construction projects in the first half of the year, effectively minimizing power
outages and steadily improving regional power supply quality.

During the critical peak summer power consumption period, the intelligent switch
upgrade has further consolidated the grid’s operational stability. Moving forward,
State Grid Changzhou will continue to optimize construction methodologies and refine
service standards. By prioritizing uninterrupted power operation in all grid upgrade
and renovation projects, the company will normalize the service philosophy of **"
No power interruption equals optimal service"**, delivering consistent, reliable
and people-centric power protection for local households and industrial users.
