Application: Cast resin dry type transformer is widely applied to the power grid, solar power plant, wind power plant, hydropower plant, nuclear power plant, infrastructure, real estate, etc…
After-sales Service: We have a professional aftersales engineer team, each aftersales engineer has more than 3 years of experience. And we also have localized technical backup to offer timely support in Malaysia, South Africa, Egypt, Dubai, UAE, Brazil.
Core:
The core is manufactured from cold-rolled grain oriented (CRGO) silicon steel. The steel sheets are cut into required dimensions on automated machines thereby ensuring reduced air gap low exciting current and low noise. Each lamination is insulated from each other to ensure a long trouble-free lifetime of the core. Using 45° stepping all leaning lamination way to laminate. So the no-load current are reduced efficiently.
Windings:
Windings are uniformly insulated and its material could be coopper and aluminum.
Full power tappings is provided in the LV wiinding. Tap changing settings is implemented as per client’s or contract’s datasheet, with pad-lockable slots on each tap change position.
