Expanding in the High-Voltage Market, Advancing into North America
As clean energy investment accelerates and electricity demand from AI-driven data centers climbs across North America, the need for reliable, high-performance high-voltage electrical solutions has increased. Sieyuan Electric, a leader in high-voltage electrical equipment, announced that its independently developed Dead Tank Circuit Breaker (DTCB) series is fully ready to serve North American customers.
Sieyuan Electric specializes in power transmission, transformation, distribution, and consumption, providing equipment manufacturing and engineering services to clients around the world. The company operates three dedicated R&D centers that drive innovation across its subsidiaries and support a proprietary, end-to-end development ecosystem.
Jiangsu Rugao High Voltage Electric Apparatus Co., Ltd., a wholly owned subsidiary of Sieyuan Electric, focuses on the research, development, and production of high-voltage switchgear. This includes disconnectors rated up to 800kV, circuit breakers rated up to 550kV, and hybrid gas-insulated switchgear rated up to 252kV, all produced at a facility equipped with advanced production infrastructure and automated manufacturing lines.
The LW58A Dead Tank Circuit Breaker series represents a new generation of high-voltage electrical equipment engineered to meet the demands of North American infrastructure. Key specifications of the series include a voltage range of 38kV to 550kV, a maximum rated current of 5,000A, and a rated short-circuit breaking current of 63kA. The series uses SF6 gas or environmentally friendly mixed gas for insulation and arc extinguishing, featuring a design that allows for more than 10,000 operations and a projected service life exceeding 30 years.
Sieyuan's production processes conform to ISO quality standards, with critical components manufactured in-house. The LW58A series has a lead time of as short as four months and is supported by dedicated overseas service teams for North American customers, who can provide on-site installation guidance and a response commitment of eight hours. Sieyuan's equipment is currently functioning in data centers, renewable energy projects, and other critical applications throughout North America.
