New-type ceramic-based composite insulated dry-type transformer

Centered on ceramic-composite insulation technology, we are redefining the performance boundaries of dry-type transformers, reactors, and packaged substations. Our products feature innovative elastic-capacity technology, specifically designed for scenarios with highly fluctuating loads. They can handle additional energy demands beyond their rated capacity, perfectly matching transient peak conditions such as grid integration of new energy sources and data center capacity expansions.
Core advantages:
Safe and reliable, maintenance-free: The all-aluminum winding system features an epoxy resin with a precisely matched thermal expansion coefficient, completely eliminating the risk of cracking and partial discharge caused by thermal stress differences. Its Class F1 flame-retardant self-extinguishing properties, combined with Climate Class C3/E3 ratings, enable zero-maintenance operation in extreme environments such as plateaus, deserts, and tropical regions.
Lifecycle Cost Advantage: The lightweight structure significantly reduces transportation and installation costs. With low-loss oriented silicon steel and high-efficiency design, coupled with a wide capacity range and coverage of all voltage levels, the system markedly lowers both initial power plant investment and long-term operational losses.
