    Product Introduction

    This 50 KVA transformer was delivered to South Africa in 2017. the rated power of the transformer is 50 KVA. It is a step-down transformer 11kv to 0.415kv, the primary voltage is 11kv, the secondary voltage is 0.415kv. It is a hermetically sealed transformer without conservator, it can make transformer oil completely isolated from the air and sunlight to avoid oxidation and moisture of transformer oil, so as to slow down the aging speed of transformer insulation and prolong the service life of transformer. Our 50 KVA distribution transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time.

    SCOTECH ensure each one of our delivered transformers had passed the full acceptance test and we remains 0 fault rate record for more than 10 years so far, oil immersed power transformer is designed in accordance with IEC, ANSI and other major international standards.
