CHSH pushes KEMA-tested substation transformers for compact grids

Shenheng Power Equipment Co., Ltd., also known as CHSH, is promoting its distribution transformer systems for substation projects as China and global buyers shift toward compact, prefabricated power equipment. The company is leaning on KEMA type testing, space-saving designs and low-noise, sealed transformer technology to target industrial, renewable and urban grid projects.

Why it matters: - Compact substation packages are replacing larger, open-air installations as cities, industrial parks and renewable sites demand more reliable power in less space. - KEMA type testing matters for export buyers because it provides third-party verification of short-circuit, thermal and mechanical performance. - CHSH is positioning its transformer systems for projects that need safer, quieter and more compact distribution infrastructure.

What happened: - Shenheng Power Equipment Co., Ltd. promoted its distribution transformer for substation project offerings on June 25, 2026, from Wenzhou, Zhejiang, China. - The company highlighted its KEMA certification as proof that its equipment meets international safety and performance benchmarks. - CHSH also pointed to its role as a supplier for the State Grid of China. - The company offered a summary of its product line, manufacturing history and substation designs. - More information is available on the company’s website.

The details: - The company said its roots date to 2001. - CHSH said it expanded in 2012 with a capital injection and an integrated R&D and manufacturing model. - The company said it added advanced production equipment in 2015. - CHSH said it built a dedicated R&D team in 2019 focused on complete transmission and distribution systems. - The company operates a 15,000-square-meter facility. - Its product range includes amorphous alloy transformers, dry-type units and fully insulated inflatable cabinets. - The company said its S11-M and S13-M series use fully sealed corrugated oil tanks that do not require an oil conservator. - CHSH said the sealed design helps prevent insulation aging and moisture ingress. - Its photovoltaic containerized systems integrate a step-up transformer, a high-voltage ring main unit and low-voltage switchgear. - Those solar-focused units carry an IP43 protection grade and are designed for temperatures from -35°C to +40°C. - The American-style ZGS and European-style YB substations are built for space efficiency. - CHSH said the ZGS series uses only one-third to one-fifth the space of traditional European substations of the same capacity. - The company said the dead-front design keeps live parts enclosed for safer public-area use. - The systems are rated for high short-circuit resistance and lightning impulse protection up to 75kV for high-voltage windings. - CHSH said its copper windings and precision-wound cores can reduce noise to as low as 45 dB. - The company said its enclosures use corrosion-resistant stainless steel or aluminum alloy for protection against chemical corrosion and seismic activity.

Between the lines: - CHSH is tying its pitch to two market shifts: tighter urban land use and the rise of distributed energy projects. - The emphasis on low-noise, sealed and dead-front designs suggests a focus on sites where safety, footprint and maintenance costs matter as much as raw electrical capacity. - The company is also signaling alignment with a broader industry move away from SF6-based equipment toward more environmentally friendly insulated systems.

What’s next: - CHSH said future product development will emphasize environmental protection gas ring main units and solid-insulated systems. - The company is targeting applications including shipyards, data centers, high-tech industrial zones and renewable energy sites. - The main commercial goal is to keep offering compact, high-performance power infrastructure for projects that cannot tolerate outages.

The bottom line: - CHSH is using KEMA certification, compact engineering and integrated substation design to compete in a market that wants more power hardware in less space, with higher reliability and lower maintenance.
