Product Details

Product Introduction

SCOTECH’S 7.5 MVA electrical power transformer was delivered to South Africa in 2014. the rated power of the transformer is 7500 KVA. It is step down transformer, the primary voltage of the transformer is 22 KV and secondary is 6.6 KV. We adopt high quality copper as our winding material to make it have better mechanical strength to withstand the high current during short-circuit, our 7.5 MVA power transformer was designed with advanced technology 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, our oil immersed power transformer is designed in accordance with IEC, ANSI and other major international standards.

What is a core type transformer?

In core-type transformer, the windings are given to a considerable part of the core. The coils used for this transformer are form-wound and are of cylindrical type. Such a type of transformer can be applicable for small sized and large sized transformers. In the small sized type, the core will be rectangular in shape and the coils used are cylindrical. The figure below shows the large sized type. You can see that the round or cylindrical coils are wound in such a way as to fit over a cruciform core section. In the case of circular cylindrical coils, they have a fair advantage of having good mechanical strength. The cylindrical coils will have different layers and each layer will be insulated from the other with the help of materials like paper, cloth, micarta board and so on.
