704KVA Cast Resin Dry Type Power Transformer 6KV To 0.5KV
Distribution Cast Coil Transformer
This 704 kVA three-phase cast resin transformer efficiently
converts 6000V primary voltage to 530V secondary, Equipped with
off-circuit tapping (±2×2.5% adjustment) , while AN/AF cooling
(natural/forced air) supports continuous operation with a 100K
temperature rise. The cast coil transformer Compliant with IEC60076
international standards, is a compact structure, low-noise,
low-loss, moisture resistance, flame retardant, cast resin dry-type
transformer.

Dry transformer features
1)Moisture-proof and corrosion-resistant ability , and it can run
normally at 100%humidity,especially for work in extreme
environmental conditions.
2)Lost loss, small local discharge, small noise, and strong heat
dissipation capacity, can run 150%of the rated load operation.
3)High the whole mechanical strength of the cast coil withstand
sudden short -circuit capability.
4)Safe, fire prevention, no pollution, can be installed directly in
the load center.
5)Simple maintenance and installation, low comprehensive operating
costs.
