Three Phase Customizable 35KV Level Dry-type Distribution Transformer
Product Overview
The Three Phase Customizable 35KV Level Dry-type Distribution Transformer is an advanced epoxy resin cast dry-type power transformer engineered for medium-voltage distribution networks. Utilizing state-of-the-art vacuum casting technology with high-grade epoxy resin, this transformer delivers exceptional electrical performance, operational reliability, and environmental safety. The dry-type design eliminates the need for oil or other hazardous liquids, making it an environmentally friendly and fire-safe solution for modern power distribution systems.
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 an ideal solution for stepping down 35kV grid power to lower distribution voltages (0.4kV, 10kV, or custom voltages) for industrial, commercial, and infrastructure applications.
Whether you require standard configurations or fully customized solutions—including multi-tap designs, dual-voltage outputs, or multi-winding arrangements—our engineering team can tailor the transformer to meet your specific grid requirements and application needs.
