Dry Type Transformer

Resin-cast dry-type transformers are our company’s flagship product. The design, management, and production team is led by Mr. Li Xianming, our transformer business founder, Deputy General Manager, and Chief Engineer — all team members are seasoned professionals in the industry.

In the mid-1990s, the Chinese central government decided to introduce dry-type transformer technology from Germany to meet the growing power demand in domestic applications such as airports, subways, and hospitals, as well as the stringent requirements these environments place on safety, reliability, environmental performance, and ease of maintenance. To this end, a team of five German technical experts was invited to transfer dry-type transformer design and manufacturing expertise to core engineers across China’s transformer industry.

Around 2005, Mr. Li Xianming was invited to undertake a further study visit to Germany, where he served as a dry-type transformer design and manufacturing guidance expert for PC Company (Germany) in Southwest China, and was involved in the establishment of multiple dry-type transformer manufacturing facilities.

Mr. Li brings 45 years of experience in the transformer industry, including nearly 30 years focused specifically on dry-type transformers. The dry-type transformers manufactured by the veteran team he has assembled are characterized by high reliability, low noise, and low losses, making them well suited for demanding applications such as five-star hotels, residential buildings, hospitals, subways, and airports.

Our dry-type transformers cover a capacity range of 30 kVA to 8,000 kVA at voltage levels of 35 kV and below. The SCB18 series meets the latest EU Tier 2 energy efficiency requirements introduced in 2019, in accordance with Commission Regulation (EU) No. 548/2014 of 21 May 2014.

Oil Immersed Transformer

Our oil-immersed transformers deliver outstanding performance in both stability and reliability, as well as energy efficiency.

Oil-immersed transformers are the product with which our transformer business founder, Mr. Li Xianming, first became acquainted at the age of 16, when he began his apprenticeship at a state-owned transformer factory. Our oil-immersed transformer products embody the core values of reliability and soundness that Mr. Li upheld consistently throughout his long career in state-owned enterprises — from apprentice, to technician, to Chief Engineer.

Equally, the design, management, and production team assembled under the leadership of Deputy General Manager and Chief Engineer Mr. Li Xianming comprises exclusively seasoned industry professionals, providing a solid guarantee of consistent product quality and reliability.

Our oil-immersed transformer range covers on-load tap-changing and off-load tap-changing power transformers, as well as distribution transformers, rated at 132 kV / 63 MVA (63,000 kVA) and below. Our S22 series oil-immersed transformers achieve energy efficiency levels that surpass the EU Tier 2 efficiency requirements implemented in 2019, as set out in Commission Regulation (EU) No. 548/2014 of 21 May 2014. Our S22 Series Oil Immersed Transformer meets and These products are widely used across a broad spectrum of applications, including:

  • Main and distribution transformers in the State Grid network
  • Step-up transformers for hydropower and thermal power plants
  • Step-up transformers for photovoltaic and wind power generation
  • Distribution networks within urban power grids
  • Last-mile distribution networks in rural and remote areas
  • Distribution transformers for landscape lighting projects
  • Power distribution for residential communities
  • Dedicated transmission and distribution lines for factories and mines

LV/MV/HV switchgear

Our LV/MV/HV switchgear team carries the legacy of the Former Sichuan Electrical Switchgear Factory — once a designated supplier of switchgear for Tiananmen Square in Beijing, dating back several decades. The core members of our switchgear team come from the former Chuankai Electric, which was the No. 2 branch factory of the former Sichuan Electrical Switchgear Factory.

Our switchgear design and manufacturing team is led by Mr. Zhang Shaokuan, General Manager of our company. A graduate of Shanghai Jiao Tong University, Mr. Zhang brings over 30 years of technical and management experience in the HV/LV switchgear industry, and previously served for many years as Head of Switchgear Engineering at leading domestic manufacturers.

The switchgear products designed and manufactured by our company are deployed across a wide range of applications — including factories, schools, hospitals, airports, mines, industrial parks, military facilities, oil extraction sites, and power plants — and have earned widespread recognition and acclaim from our customers.

Prefabricated Substation

Our prefabricated substation offering comprises two product lines: prefabricated cabin-type substations and traditional box-type substations.

In recent years, in response to customer demands for greater reliability, ease of transportation, and the ability to be redeployed multiple times, we have developed a series of prefabricated cabin-type substations built around high-strength container-style enclosures, which we fabricate in-house. These products have been widely adopted across a broad range of applications, including ports, airports, mines, oil and gas extraction projects, electric vehicle charging station projects, and urban power supply networks.

The prefabricated substation team is likewise led and assembled by General Manager Mr. Zhang Shaokuan. The team brings together professionals across generations — from seasoned veterans to mid-career engineers to young talent — providing a strong guarantee of reliable performance across our prefabricated substation product range.
