Amorphous Metal Core Pole-Mounted Transformers

• 22.9 kV-y single-phase transformer for multi-grounding distribution system

• Amorphous material core adopted for energy saving with remarkable no loss-load reduction

Features

• Use of amorphous metal core

  – One-third no loss-load compared with silicon steel plates

• Economically feasible in highly fluctuated load areas

• Decreased loss & increased overload due to narrow range of

 temperature rise


Rating

• Capacity : 10, 20, 30, 50, 75, 100 kVA

• Frequency : 60 Hz or upon client's requirement

• Primary voltage : 13.2 kV

• Secondary voltage : 230 V or client's requirement

• Tap voltage : 3 taps
