Are dry transformers more expensive than oil-filled ones?

Initially, dry transformers can be more expensive than oil-filled transformers, but they might have lower maintenance and operational costs over time.

How to choose the capacity of dry-type transformers?

Based on the total load power, reserve an appropriate margin (usually selected at 70% -80% of the load rate), while considering future expansion needs. Suggest providing a load list for our engineers to assist in calculating.

Is dry-type transformer noisy?

The noise level of conventional products is controlled between 50-65 decibels. For places with high noise requirements such as hospitals and residences, low-noise design can be implemented, with a minimum of 45 decibels.

Product Q&A

Q:What is a dry transformer?

A dry transformer is an electrical transformer that uses solid insulating materials instead of liquid, such as oil, to insulate between the winding and the core.

Q:What is the difference between dry type and oil-immersed transformers?

Dry type transformers use air or resin for insulation,making them safer,fire-resistant,and maintenance-free,while oil- immersed transformers require oil for cooling and insulation.

Q:What does 35 years of experience mean for dry-type transformers?

This means that our design has been validated through thousands of projects and has accumulated mature experience in key areas such as insulation technology, heat dissipation structure, and partial discharge control. The customer received a device that has been tested over time and has been running stably for a long time.

Q:What is the biggest advantage of dry-type transformers?

Safe and environmentally friendly - no oil leakage risk, no fire hazard, maintenance free, in compliance with fire safety requirements. Simultaneously running with low noise, suitable for densely populated areas.

Q:Where are dry transformers commonly used?

They are often used in industrial settings, commercial buildings, and indoor applications where space is limited and fire safety is a concern.
