K factor is value used to determine how much harmonic current a transformer can withstand without exceeding its maximum temperature level. Huge numbers of single Phase loads like computers also create non-linear harmonics. A standard Transformers can not handle the harmonics due to non-linear loads. When harmonics enter in to the transformer the core gets saturate as result it produced lot of heat causes the failure of transformer. k-rated transformers are Specially designed to with stand this non-linear harmonics. K-rateing differs according to the harmonic levels like K-1, K-4, K-7, K-13, K-20, etc.,
We are designing our K-Rated Transformers according to its guide lines and Specification given by ANSI C57 standard NFPA-70, UL 1449 and UL 1567. We use high grade CRGO laminations for our K-Rated Transformers. Our K-Rated Transformers are Class-H which will with stand 180 continuously. We use notching
type lamination for our K-Rated transformers, because of that our Transformer
core will not saturate even in high Voltage.
We also manufacture Aluminum wound Transformers with the same quality to minimize the initial investments Our design will support to maintain the same performance of Copper Transformers in Aluminum Transformers also. We can manufacture Aluminum Wound Transformer Upto 500 KVA .
