🔍 Product Overview
ABB Dry-Type Transformers are a safe, fire-resistant, and environmentally friendly alternative to oil-immersed transformers. Designed for indoor and outdoor use up to 36 kV and up to 20 MVA, these transformers are ideal for commercial, industrial, and utility applications where fire risk, environmental impact, and maintenance costs are key concerns.
ABB’s vacuum cast coil (VCC) and resin encapsulated technologies ensure excellent insulation, moisture resistance, and mechanical strength, even in harsh or high-humidity environments.
