Three kinds of buyers, three ways to work

We do not quote everything to everyone. Each channel below has its own quotation logic and delivery rhythm.

EPC & electrical contractors

Your schedule is already fixed by the client. Standard ratings ship in 7 days; custom builds are scheduled against your drawing. We supply datasheets and reference lists for your bid package.

Quote per project →

Panel builders & OEM

Repeat supply against your drawings and batch plan. Terminal layout, cable entries and painting spec aligned to your process to cut rework on your line.

Annual framework →

Traders & overseas buyers

Built to IEC / ANSI or local voltage and frequency, CE documentation, neutral packing and English labels available. Trial orders of 1–2 units welcome.

MARKETS / SOUTHEAST ASIA & AFRICA

Built for the grids you actually install into

Tropical humidity and weak grids are not edge cases for us — they are the two configurations we build most often for Southeast Asia and Africa. Tell us the destination country and the grid code, and we quote to it.

Southeast Asia — heat, humidity, 50 Hz

Anti-condensation heaters and tropical-grade varnish; IP54 enclosures and C5-M paint for coastal sites; 10 / 20 / 35 kV classes matching local distribution; single-phase pole-mounted units for rural feeders. 60 Hz builds for the Philippines.

Dry-type range →

Africa — weak grids, high ambient, long spares chain

Wider tap ranges and overload margin for unstable supply; 50 °C ambient derating on request; dust-resistant IP5X enclosures; spare bushings, gaskets and fuses shipped with the unit; documents prepared for LC and pre-shipment inspection.

03 / LEAD TIME

Three tiers, stated in the contract

"7 days" applies to standard ratings on expedited terms — not to every order. Better to be clear now than to argue later.

Order typeLead timeConditions
Standard rating, expedited7 daysModel on stock list, drawing confirmed, down payment received
Regular order15–30 daysStandard parameters, scheduled batch
Custom / export build25–35 daysSpecial voltage, frequency, IP rating or certification
Reference only. Actual lead time is per contract. Export orders need extra time for certification documents and inspection.

05 / FAQ

Five questions buyers ask first

Is 7 days realistic?
For standard ratings, yes. The model must be on our stock list, the drawing confirmed the same day and the down payment received. Custom builds are quoted separately.
Are you a factory or a trading company?
We are a manufacturer. The plant is at No.261 Weishi 16th Road, Yueqing Economic Development Zone, Yueqing, Wenzhou, Zhejiang, China. Factory visits — in person or by video — are welcome.
Can you supply above 35 kV?
No. We focus on 35 kV and below (10 / 20 / 35 kV), up to 20,000 kVA per unit. For higher voltage we would rather point you to a specialist than waste your time.
What about certifications for my market?
We hold ISO 9001, ISO 14001 and ISO 45001 system certificates, a CE Verification of Conformity (LVD + EMC) and CCC self-declarations for the GCS, GGD, GGJ and JP low-voltage assemblies. If your market requires additional type tests or a local certificate, tell us the destination and we will confirm feasibility and timing case by case.
What do you need to quote?
Rating or kVA, voltage ratio (e.g. 35/0.4 kV), quantity, application, and whether export packing and documents are required. A drawing is fastest.
