Other Features:

a). The integrated unit is hot vacuum cast in an insulating resin, to achieve a discharge free high voltage insulation. The epoxy resin used in the outdoor environment has a whole full-casing design
b). Secondary terminals are covered by stainless steel metal to seal.

c).A secondary shorting switch strap provided in the junction box.

d). The lid of the secondary terminal box of the transformers ( metering unit) are provided with sealing facilities by using sealing screws to prevent access to the unauthorized persons.

e). Lifting tackles are provided for convenient and safe handing of the combined transformers.

f). External terminals for connection to overhead line (primary side) suitable for a range of stranded copper or aluminum conductors of 20 sq mm to 100 sq mm.
