At the waste incineration power plant, the reliability of low-voltage power supply is directly related to the harmless disposal of urban domestic waste and the stable operation of green power generation. In 2026, Changshu Switchgear collaborated with the owner, general contractor, and local service providers to jointly tackle the low-voltage key component renewal and upgrade project for the first phase of Guiyang Zhongdian Environmental Protection Power Generation. From technical solution support and performance guarantee to on-site emergency rapid closure, the project was steadily implemented, becoming a replicable and scalable benchmark sample in the track of updating and replacing existing equipment for environmental protection incineration power generation.

Guiyang Zhongdian Environmental Protection Power Generation Co., Ltd

Stable performance, quality wins customer trust
The Guiyang Zhongdian Environmental Protection Power Generation Project is equipped with four incineration lines that can process 600 tons of waste per day, and can process up to 2400 tons of household waste per day. The low-voltage electrical equipment for the project is supplied by Changshu Switchgear. The first phase was put into operation in 2016, and the components are products from other brands; The second phase will be put into operation in 2021, using Changshu Switch CW3 series products for long-term stable and reliable operation. After nearly a decade of operation, the first phase of the original product has experienced frequent failures. Compared with the stable performance of the second phase Changshu switch, the owner has decided to initiate the renovation of the low-voltage key components in the first phase. After receiving the request, the customer service team of Changkai quickly understands the on-site working conditions and renovation requirements, provides technical solution support, and lays the foundation for the smooth construction of the project.
Collaborative efforts, timely delivery to ensure the pace of transformation
The project will be launched in February 2026, and the regular customer service team will collaborate with relevant departments to track it; In March, the team confirmed the construction plan with the owner and coordinated services with local partners, planning to enter the construction site after the National Day holiday. In September, the production support team responded quickly, coordinated production scheduling and delivery, and fully matched the pace of on-site renovation. The first batch of supply includes 19 units for public section 1 and 19 units for public section 2. The remaining 30 circuit breakers will undergo on-site renovation in 2027. The first batch of products was delivered to the site as scheduled on October 16th, and the first phase of the low-voltage renovation project officially started. The delivery pace matched the on-site renovation plan accurately.

On site emergency response, quick change service is flexible and reliable
During the renovation process, there was a sudden technical adaptation issue on site: the original circuit breaker was equipped with two sets of independent three position indicators, while the Changshu switch was equipped with one set of three position indicators for the common end. The incoming busbar cabinet urgently needs to be restructured and matched. The regular customer service team promptly receives requests, synchronizes with the technical and production teams to respond quickly, urgently allocates parts, and delivers them to the site the next day; At the same time, the local service provider team was coordinated to rush to the site to provide technical services, ensuring the smooth implementation of the restructuring without delaying the renovation period, reflecting the flexibility and reliability of the quick change service.
The steady implementation of the project is a joint operation of internal and external coordination, from technical solution support, performance guarantee, to production scheduling and supply guarantee, and rapid closure of on-site issues. Internally, multiple departments such as sales, technology, production, and quality assurance break down barriers and collaborate efficiently; Externally, closely collaborate with upstream and downstream partners such as property owners, general contractors, and local service providers, rely on localized service resources, respond quickly to on-site demands, and achieve win-win situations for all parties.

Benchmark significance, deeply cultivating the stock operation and maintenance market
This renovation further strengthens the low-voltage power supply safety defense line of the garbage incineration power plant and improves the reliability of electricity consumption in the factory area. The project has also become a replicable and promotable benchmark sample for Changshu Switch in the track of updating and replacing existing environmental incineration power generation equipment, accumulating practical experience for the subsequent market development of existing operation and maintenance transformation. Changshu Switch will continue to work together with our customers and partners to safeguard the stable operation of the power system with our strong product strength and full chain value-added services.
