dry-type power transformers
1. Level 1 Energy Efficiency: Less loss, maximum energy savings, maximum energy savings and low long-term operating costs.
2. Ultra-low noise: It operates silently, suitable for hospitals, schools and residential areas.
3. Safety and fire resistance: Oil-free, made of epoxy resin, explosion-proof, environmentally friendly and maintenance-free.
4. Stable and reliable: short circuit resistance, low partial discharge, long service life, suitable for new energy sources and data centers.
1. Product overview
SCB series dry type transformers, manufactured by epoxy resin casting, are energy efficient and high performance products.
The design utilizes ultra-thin 0.23 mm high-permeability silicon steel sheets, a multi-stage stepped-lap core technology, and high-precision vacuum casting. Core losses reach the highest levels in the industry. It is oil-free, fire-resistant, explosion-proof, and environmentally friendly.
