A supply-chain specialist for transformer accessories — built for buyers who need speed and flexibility.
Who We Are
Specialists in transformer protection accessories — not a general trading company.
Yuan Global Trade is a specialist exporter of power transformer protection & control accessories — Buchholz gas relays (QJ series), pressure relief valves (YSF5), oil level gauges (UZF), breathers, butterfly valves and conservator capsules. Behind every product is a manufacturing base in Shenyang, China with over 20 years of grid-support and export history across the Middle East and Southeast Asia.
We work as the export and sourcing desk for transformer manufacturers, power utilities, EPC contractors and substation O&M teams — solving the four problems that stall accessory procurement: (1) identification & matching — send a nameplate or photos of the old part and we identify the model and confirm dimensions before you pay; (2) small & mixed orders — one transformer's full accessory bill consolidated into a single shipment; (3) verifiable quality — pre-shipment photos and inspection records, third-party inspection welcome; (4) response speed — quotations within 24 hours, replies within working hours.
Manufacturing partners
ISO 9001-certified accessory manufacturers in Shenyang with grid-scale references and national-level test reports.
Quality control
Inspection records with every order. Third-party inspection (SGS / BV / TÜV) welcome at loading.
Long-term supply
