Product Overview
The 80kVA dry type transformer utilizes epoxy resin casting insulation technology and features a three phase, oil free, fire resistant, and environmentally friendly structural design, positioning it as a medium capacity small distribution transformer. The 3 phase transformer is suitable for power distribution systems and is commonly used in voltage transformation, power distribution, and stable power supply scenarios. Its compact structure features low loss, low noise, maintenance free operation, and strong short circuit resistance, enabling long term stable operation in indoor, basement, small factory, commercial building, data center, and computer room environments. It is a reliable choice for industrial, construction, municipal, new energy, and small power grid sectors.
80kVA dry type transformers cover diverse application needs: they can perform voltage step down tasks to meet various voltage conversion requirements, and can also be used in small and medium capacity power distribution systems, or as three phase distribution transformers in industrial power systems. With mature standardized design and stable manufacturing processes, transformer for power maintains a reasonable inventory year round to support rapid delivery. Products strictly comply with multiple international and regional standards such as IEC, GB, JIS, ANSI, IEEE, and UL, while also meeting energy efficiency ratings (Level 1/Level 2) and SCB series requirements. All products have passed rigorous testing and certification according to relevant standards.

Dry-Type Transformer FAQ
1. What is a dry type transformer?
A dry type transformer uses epoxy resin or air as insulation instead of oil. It is fire safe, maintenance free, and designed for indoor installation.
2. Dry type vs oil immersed – which is better?
Dry type: safer indoors, no fire risk, zero maintenance, higher cost.
Oil immersed: better for outdoor, lower cost, needs oil testing. Choose based on your installation site.
3. Where can I install a dry type transformer?
Indoors – buildings, hospitals, data centers, factories, shopping malls. For outdoor use, add a weatherproof enclosure.
