The Real Challenges Purchasing Managers Face

1. High purchase price – Up to 30% more than OEM alternatives, hurting project budgets.
2. Inconsistent quality – Unexpected failures increase downtime and maintenance costs.
3. Long lead times – 8‑12 weeks delay slows plant commissioning.
4. Regulatory uncertainty – Missing CE, UL, or RoHS certifications stalls cross‑border shipments.
5. Limited customization – Off‑the‑shelf units rarely meet exact voltage, frequency, or enclosure requirements.

Result: Projects run over budget, miss milestones, and risk non‑compliance.

Frequently Asked Questions

How does a power transformer work internally?

It transfers electrical energy between two windings via magnetic induction. The primary winding creates a magnetic flux in the core; this flux induces a proportional voltage in the secondary winding, stepping voltage up or down while keeping frequency constant.

Can you customize voltage ratios and tap changers?

Yes. Our OEM/ODM team designs custom winding configurations, tap‑changer types (on‑load/off‑load), and enclosure dimensions to match your exact system requirements.

About Power Transformer

What is the typical delivery time for a 500 kVA order?

Standard production: 15 days after final design approval; expedited (express) production: 7 days with an additional 10% surcharge.

Do you provide on‑site installation support?

We offer optional on‑site commissioning, testing, and training packages. Our engineers can travel worldwide; costs are quoted per project.

How are payments handled for first‑time overseas buyers?

Standard terms: 30 % T/T deposit, 70 % balance before shipment. For qualified accounts, we accept L/C at sight or open account after 30 days of successful trade.
