The high and low voltage coils are made of copper conductors, thinly insulated, and are poured and cured with epoxy resin in a vacuum state.
The wire insulation adopts patented technology - the product has high mechanical strength, strong heat aging resistance, and small partial discharge.
The short-circuit impedance unbalance rate ≤1.0%
The imbalance rate of the two-half crossing impedance is ≤1.0%
The no-load voltage unbalance rate of the two single groups ≤ 1.0%
The temperature rise limit of the winding < 68.5K
