Importer considerations:
Sieyuan spans equipment supply and complete power-system projects. A distributor should define whether the offer is a component, a tested assembly or an engineered system, and identify the responsible supplying entity for each part. Switchgear and transformer ratings, protection settings, storage controls and charger interfaces require different commissioning and service capabilities.
Commercial evaluation path:
Start with one utility or industrial project and freeze its equipment ratings, interfaces and acceptance criteria. Match the offered configuration to relevant type-test evidence, review protection and control drawings, and agree factory and site acceptance tests. Qualify storage, charging or automotive-electronics additions separately, with a named service owner, spare-parts plan and change-notification process.

Target customers
utilities, grid contractors, renewable developers, industrial and infrastructure owners, EPC firms, electrical distributors and qualified system integrators
Export experience
Sieyuan's official English profile and publications describe business across more than 100 countries and multiple equipment and EPC lines. The headquarters page also separates Shanghai from numerous operating subsidiaries, so contract, plant and local service roles must be confirmed for each project.
Partner and service support
After-sales support
Maintain project drawings, type-test scope, gas and insulation records, protection settings, component schedule, firmware, FAT and site acceptance by serial. Control mechanisms, breakers, disconnectors, CTs, VTs, relays, seals, density monitors and enclosure changes; monitor operations, leakage and alarms; preserve handling and recovery procedures; and stock project-matched coils, motors, mechanisms, relays, sensors, seals and service tools.
