25kva single phase pole mounted distribution transformer 13.2KV to
240V 37.5kva 50kva 250 kva 100kva 150kva
In the distribution network with decentralized power supply,
single-phase transformer has significant advantages as a
distribution transformer. It can reduce the length of low-voltage
distribution lines, reduce line losses and improve power supply
quality. It adopts a high-efficiency energy-saving wound iron core
structure design. The transformer is characterized by adopting pole
mounting type suspension installation method, small volume, small
infrastructure construction investment, reduction of low-voltage
power supply radius and can reduce low-voltage line losses by more
than 60%. The transformer adopts a fully sealed structure with
strong overload capacity, high reliability in continuous operation,
simple maintenance and long service life.
