Frequently Asked Questions

Are you a manufacturer or trading company?

We are a dedicated manufacturer specializing in customized power transformers, switchgears, and substations designed to meet international standards.

How do you handle quality control?

All products undergo 100% inspection and testing before delivery. We provide video inspections or detailed reports to ensure quality assurance.

What is the typical delivery time?

Standard orders usually take about 15 - 20 days. Customized designs may vary based on technical specifications.

What is the difference between copper and aluminum windings?

Copper offers better long-term durability and efficiency but comes at a higher price. Aluminum is more cost-effective. Both perform reliably when designed correctly.

Do your products have international certifications?

Yes, our products carry CE, 3C, and CQC certificates. We can also assist in applying for other specific regional certificates if required.

What are your payment terms?

We generally accept T/T (30% deposit and 70% balance against copy of BL) and L/C.
