CHSH expands utility-grade MV switchgear business over 24 years

Shenheng Power Equipment Co., Ltd. says its CHSH brand has grown from a local producer in Yueqing, China, into a supplier of utility-grade medium-voltage switchgear for domestic and international power networks. The company is leaning on insulated, smart and SF6-free designs as grid operators demand more compact, reliable equipment.

Why it matters: - Medium-voltage switchgear protects power networks from overloads and faults, helping prevent local failures from cascading into wider outages. - Utility operators are facing more demand for compact, reliable and intelligent distribution equipment as cities grow and grids add distributed energy resources. - More information on Shenheng Power Equipment Co., Ltd.'s distribution solutions is available on the company's website.

What happened: - Shenheng Power Equipment Co., Ltd. said its CHSH brand has spent 24 years building utility-grade medium-voltage electrical switchgear capabilities. - The company was established in 2001 in Yueqing City, Zhejiang Province. - CHSH described Yueqing as a major center for China's electrical equipment industry. - The company said it is a qualified supplier to the State Grid of China. - CHSH said its business now covers high- and low-voltage transmission and distribution equipment.

The details: - MV electrical switchgear typically operates in the 3kV to 40.5kV range. - The equipment is used in industrial plants, commercial high-rises, renewable energy sites and utility grids. - The industry is shifting from bulky air-insulated switchgear toward gas-insulated and solid-insulated designs. - Premium utility-grade systems use vacuum interrupters and high-grade copper busbars to support repeated switching operations. - Ring main units are a key product category for loop-type distribution networks in dense urban areas. - Modern MV switchgear often includes sensors for temperature monitoring, partial discharge detection and remote communication. - CHSH's MV switchgear offerings include 24kV and 36kV products. - The company's RMU metal-enclosed cabinets support current ratings from 630A to 1250A. - CHSH said its cabinets are fully insulated and fully sealed. - The company also offers cable branch boxes and prefabricated substations for outdoor deployment. - CHSH said its solid-insulated ring main units eliminate the need for SF6 gas. - The units use epoxy resin to encapsulate high-voltage components. - CHSH said the design supports operation in coastal environments and polluted industrial zones. - The company said its portfolio also includes transformers, fully insulated inflatable cabinets and intelligent solid-insulated ring main units. - CHSH said its manufacturing approach emphasizes a strong after-sales system and stable quality.

Between the lines: - The move away from SF6-based designs reflects broader pressure for greener electrical infrastructure. - Digital monitoring is becoming a baseline expectation because utilities want predictive maintenance instead of reactive repairs. - CHSH's focus on sealed insulation and modular deployment fits markets where maintenance access is limited and installation speed matters. - The company's State Grid relationship suggests its products have been tested against strict utility requirements.

What's next: - CHSH said it will further integrate digital monitoring into its prefabricated substations and ring main units. - The company expects demand to rise as distributed solar, community wind and other decentralized energy resources expand. - CHSH said participation in international trade exhibitions and industry certifications has supported its expansion beyond China. - The company is positioning its switchgear for bidirectional power flows and more frequent switching cycles in future grids.

The bottom line: - CHSH is pitching itself as a utility-grade switchgear maker built for a grid that is becoming smarter, more decentralized and more environmentally constrained.
