Dry Type Transformers – Comprehensive Solutions by Evernew Transformer
Evernew Transformer is a leading Chinese dry type transformer manufacturer and supplier, specializing in high-quality dry type transformers for industrial, commercial, and utility applications worldwide. With decades of experience in transformer design, production, and quality assurance, we provide reliable, efficient, and safe power solutions that meet international standards and customer-specific requirements.
Dry type transformers are increasingly preferred for safe, low-maintenance, and environmentally friendly electrical distribution. Unlike traditional oil-immersed transformers, they rely on air or resin insulation instead of flammable oil, offering enhanced safety, fire resistance, and minimal maintenance.
1. What Are Dry Type Transformers?
A transformador de tipo seco is an electrical transformer in which air or resin serves as the primary insulation medium. They are designed for indoor or outdoor installations and can withstand high temperatures and challenging environmental conditions. Dry type transformers are commonly found in:
- Edificios comerciales – offices, malls, hospitals, and schools.
- Instalaciones industriales – factories, manufacturing plants, and automation systems.
- Infraestructuras públicas – airports, railway stations, and stadiums.
- Sistemas de energía renovable – solar farms, wind power, and microgrids.
Key advantages include:
- Seguridad contra incendios – no oil reduces fire risk.
- Low maintenance – no need for oil monitoring or leakage control.
- Environmental friendliness – reduces contamination risk.
- Versatilidad – suitable for indoor, outdoor, and high-humidity environments.

7. FAQs for Dry Type Transformers
Q1: What is the difference between dry type and oil-immersed transformers?
A: 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.
Q2: Can I choose copper or aluminum windings?
A: Yes, Evernew provides both options. Copper offers higher efficiency; aluminum is lighter and more cost-effective.
Q3: Are dry type transformers suitable for outdoor use?
A: Yes, with proper enclosure and weatherproofing, dry type transformers can operate outdoors safely.
Q4: What certifications do your transformers have?
A: Our products comply with CE, UL, TUV, CSA, and GOST, and undergo rigorous load, short-circuit, and insulation tests.
