Description

Feature

Parameter

Amorphous alloy iron core has the characteristics of low loss (equivalent to 1/3-1/5 of silicon steel sheet), low coercivity, low excitation wave, and good temperature stability. Transformers made of amorphous alloy have significant energy conservation. Especially suitable for users with low load rates, such as rural areas and developing areas. The amorphous alloy transformer core adopts three-phase five column coil iron core, and the iron core is clamped with a thin sheet forming frame structure. The low-voltage coil is of foil wound type, which has strong short-circuit resistance and advanced and reasonable structure. The overall performance index reaches the world's advanced level.

Low loss: Meet the energy efficiency requirements in the standard GB20052-2020 "Energy Efficiency Limits and Levels for Power Transformers";
Low noise: meeting the requirements of the low noise standard of the State Grid South Network;
Strong short-circuit resistance: Low voltage coils are wound with copper foil, while high voltage coils are pressed and baked with adhesive paper, resulting in high mechanical strength;
Beautiful appearance: Full polishing and rust removal, powder electric spraying paint can achieve the spraying effect of household appliances;
