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.

Construction:

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 the other to ensure a long trouble-free life of the core. Using 45° stepping all-leaning lamination way to laminate. So the no-load current is reduced efficiently.

Windings:
LV winding is manufactured with a high-quality foil conductor or copper wire and the ampere-turn is balanceable. The additional loss is low and the ability of anti-short is improved. Oil drawings of heat dispersion are scientifically used in the winding and the surface of heat dissipation is increased so the temperature is reduced and the ability of over-load is improved.

HV winding is manufactured with high quality copper wire and excellent design structure. It improves the distribution of electric field. With lighting impulse analysis the ability of anti-lighting impulse has been improved.

Transformer Test:

Most Pearl Electric cast resin dry type transformers are designed and manufactured in accordance with Standard IEC 60076-11.
Pearl Electric has four test bays for different kinds of products with a complete set of modern and updated test equipment.
Except for short circuit tests, Pearl Electric has the ability to do all routine tests, type tests, noise measurements in its own test bay.Type tests and Specials Tests have been carried out in internationally recognized independent test lab, and test reports have been obtaining, including:
1. C2/E2/F1 test report for cast resin dry-type transformer.
2. Aging test report for cast resin dry-type transformer.
3. Aseismatic report for cast resin dry-type transformer.
4. Type and special test reports for class 1E dry type transformer for nuclear power station application.
5. Type and special test reports for various traction/excitation transformers.
6. Type and special test reports for amorphous alloy core dry type transformer.
