SC(ZB) series dry type transformer

Overview

Resin insulated dry-type transformers are safe, flame retardant, non-polluting and can be installed directly in load centers. Maintenance-free, easy to install, low overall operating cost, low loss, good moisture-proof performance, can operate normally under 100% humidity, and can be put into operation without pre-drying after shutdown. It has low partial discharge, low noise, and strong heat dissipation capability. It can operate at 120% rated load under forced air cooling conditions. Equipped with a complete temperature protection control system, it provides reliable guarantee for the safe operation of the transformer and has high reliability.According to the operation research of more than 10,000 products that have been put into operation, the reliability indicators of the products have reached the international advanced level.
