Product Introduction
This 75 KVA power distribution transformer was delivered to Angola in 2016, the rated power of the transformer is 75 KVA, the primary voltage is 11kv, the secondary voltage is 400v. This is a full-sealed oil-immersed distribution transformer without oil conservator, the height of transformer is reduced, and as the transformer oil does not contact with air, the oil ageing is retarded, thus prolonging the service life of transformer. Our 75 KVA distribution transformer was designed in 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, our oil immersed power transformer is designed in accordance with IEC, ANSI and other major international standards.

75 KVA 11/0.4KV Transformer Core Assembly
The categories of silicon steel sheet
(1) According to the silicon steel sheet can be divided into four categories: low silicon steel (containing silicon 0.8~1.8%), medium silicon steel (containing silicon 1.8~2.8%), high silicon steel (containing silicon 2.8~3.8%) and high silicon steel (containing silicon 3.8~4.8%).
(2) According to rolling method can be divided into hot rolled silicon steel sheet and cold rolled silicon steel sheet.
(3) According to grain orientation, it can be divided into directional electromagnetic silicon steel plate and non-directional electromagnetic silicon steel plate.

Transformer Knowledge
Main Characteristics of a Transformer:
1.The frequency of input and output power is the same
2.All transformers make use of electromagnetic induction laws
3.The primary and secondary coils are devoid of electrical connection (except for auto transformers). The transfer of power is through magnetic flux.
4.No moving parts are required to transfer energy, so there are no friction or windage losses as with other electrical devices.
5.The losses that do occur in transformers are smaller than those in other electrical devices
