Liquid-immersed Distribution Transformers

Description
Details

Distribution Transformers are used to convert electrical energy of higher voltage; usually up to 36 kV, to a lower voltage, usually 250 or 435 V, with an identical frequency before and after the transformation.

Rated power of Liquid-immersed Distribution Transformers:
50 to 2,500 kVA normal distribution application / 2,500 to 6,300 kVA for special industrial application

Rated voltage:
HV side: 6,000 to 33,000 V; LV side: 200 to 1,000 V

Other types of Liquid-immersed Distribution Transformers:

Single-phase pole-mounted / pad-mounted Distribution Transformers 10-250 kVA
Three-phase pad-mounted distribution transformers 300-3,000 kVA
Submersible Distribution Transformers 25-500 kVA (single-phase); 100-1,000 kVA (3-phase)
Step-down-transformers: up to 500 kVA (single-phase)

Application:
suburban areas, public supply authorities and industrial customers

Advantages / characteristics:
environmentally friendly desing with MIDEL®-filling, free of maintenance (Tumetic design), low losses, low noise, long operation life time
