Description

The product of this latest series are resin cast transformers reinforced by glass fiber grid. Resin is fed by flow control pump and static control in order to prevent coils from alligator crack. The advanced cast technique ensures the resin mixture fully immerses into the space between turns and segments in order to ensure the dielectric strength and minimum partial discharge(≤5PC).

Environmental Conditions:

1. Altitude: <1000m indoor
2. Max .ambient: temperature +40℃
3.Max. daily: average temperature +30℃
4.Max .annual: average temperature +20℃
5.Min. temperature -5℃
6.Supply transformer operate under special conditions according to customer requirements.

Main Characteristics:

1.Low no-load loss and energy conservation

2.Low noise and environmental protection

3.Long service lifetime and safe and reliable performance

4.Reasonable and aesthetic structural design and exquisite manufacture craftsmanship

5.A full variety of accessories and appropriate protection measures
