香港莱斯动力变压器询价

It’s Cyrus from Royce Power in Hong Kong. As per our discussion through phone today afternoon, we would like to place another quotation order of the transformers for another overseas project in Myanmar for 1000 pieces, apart from the Auxiliary

Transformer we ordered for the SAPT project in Pakistan. Here is the requirement of the Transformer (Tx) we need for the Myanmar Telecom Project (MT):

- Nominal Capacity: 20kVA or 25 kVA (Please quote the price

Separately for both capacity)
