The transformer offers safe, flame-retardant and fire-resistant performance without causing pollution, making it suitable for direct installation at the load center.
It requires little maintenance, is easy to install and helps lower overall operating costs.
The product provides excellent moisture resistance and can operate normally in environments with up to 100% humidity. After shutdown, it can be restarted without pre-drying.
It features low loss, low partial discharge, low noise and strong heat dissipation. Under forced-air cooling conditions, it can operate at up to 150% of its rated load.
A complete temperature protection and control system provides reliable protection for safe transformer operation.
Based on operating studies of products already in service, the transformer has achieved an internationally advanced level of reliability.
