Best-selling 35KV Level Dry-type Power Transformer Airport Industrial Use
The Three Phase 35KV Level Dry-type Power Transformer is an advanced epoxy resin cast dry-type distribution transformer engineered specifically for the demanding power requirements of airports, industrial facilities, and critical infrastructure. Utilizing state-of-the-art vacuum casting technology with high-grade epoxy resin, this transformer delivers exceptional electrical performance, operational reliability, and environmental safety.
Designed for three-phase, 50/60Hz power systems, this transformer is available in capacities ranging from 30 kVA up to 25,000 kVA, with primary voltages up to 35kV. It serves as the ideal solution for stepping down 35kV grid power to lower distribution voltages (0.4kV, 10kV, or custom voltages) for airport terminals, industrial plants, commercial buildings, and infrastructure projects.
The dry-type design eliminates the need for oil or other hazardous liquids, making it a fire-safe and environmentally friendly solution—particularly critical for airports and other public facilities where fire safety regulations prohibit oil-filled equipment. The transformer has been successfully deployed in numerous landmark projects including the world's highest-altitude civil airport—Daocheng Yading Airport, Beijing Daxing International Airport, Sanya Phoenix International Airport, and the Hong Kong-Zhuhai-Macao Bridge
