Frequently Asked Questions

What's the contrast between OLTC and standard transformers?

On-Load Tap Changers permit voltage alteration whereas the transformer remains energized and serving stack. Standard transformers require de-energization for tap changes, causing control interruptions.

How frequently does the tap changer require maintenance?

With appropriate oil quality administration, the tap changer works dependably for 500,000+ cycles. We prescribe yearly assessments and oil testing to maximize benefit life.

Can you customize voltage proportions for our particular grid?

Absolutely. We tailor high-voltage and low-voltage determinations to coordinate your conveyance arrange prerequisites. Share your specialized needs, and our engineers will plan the ideal arrangement.

What cooling method should I choose?

ONAN (natural oil circulation and air cooling) suits standard 2000 kVA loads. For higher capacities or ambient temperatures, OFAF (forced air) or ODAF (forced oil and air) provides enhanced cooling.

Do you provide installation support?

Yes. We offer installation guidance, technical training, and comprehensive after-sales support. Our team helps ensure proper commissioning and long-term reliability.

Global Reach, Local Support

Our transformers power projects across Australia, New Zealand, India, Vietnam, Malaysia, Indonesia, Kazakhstan, Egypt, Kenya, and beyond. You benefit from proven performance in diverse climatic conditions and grid configurations.
