Product Introduction
This 40 MVA Electric power transformer was delivered to a substation in China in 2010, the rated power of the transformer is 40000 KVA, the primary voltage of the transformer is 110KV and the secondary voltage is 10KV. The iron core of this electric transformator is made of quality cold-rolled silicon steel sheet, and the coil is made of quality oxygen-free copper, featuring good outlook and safe running. The products are widely used in power transmission and distribution of industrial and agricultural power networks. Our 40 MVA power transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time. We also provide distribution transformer, dry type transformer, furnace transformer and rectifier transformer. If you interested in any of these items, pls do not hesitate to contact us, we will give you more details.
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 the features of on load tap changer?
On-load tap changers (or circuit tap changers), as the name suggests, permit tap changing and hence voltage regulation with the transformer on-load.
Tap changing is usually done on the HV winding for two reasons:
Because the currents are lower, the tap changer contacts, leads, etc., can be smaller.
As the HV winding is wound outside the LV winding, it is easier to get the tapping connections out to the tap changer.
