10 MVA 10000 KVA Power Transformer with OLTC 33KV To 33KV
SCOTECH‘s 10 MVA 33KV OLTC transformer was delivered to Zimbabwe in 2019 via an South Africa Company, this 10000 KVA transformer was supposed to be used in a substation for mining company, but the 33KV line voltage from the power grid is not stable, it jumps from 26 to 40kv frequently, so we designed this 33KV to 33KV OLTC transformer to regulate the primary voltage to get an stable 33KV output voltage. SCOTECH promise each one of our delivered transformers has passed the most strictly test and we remained 0 fault rate record for more than 10 years so far, our oil immersed power transformer is designed in accordance with IEC, ANSI and other major international standards.
