Product Introduction

This 125 KVA transformer was delivered to Zambia in 2003. the rated power of the transformer is 125 KVA. It is an Oil Cooled Transformer, the primary voltage is 11kv, the secondary voltage is 0.55kv. The core is made of 45 ° miter joint and step overlapping structure, which can effectively reduce no-load loss and no-load current. Our125 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.

125 KVA 11/0.55KV Transformer Oil Filling

The functions of transformer oil

Functions of Transformer Oil Electrical Insulation The main function of insulating oil in a transformer is to provide electrical insulation between the various energized parts; it also acts as a protective coating layer to prevent oxidation of the metal surfaces. Heat Dissipation Another important function of the oil is to enhance heat dissipation. Transformer cores and windings get heated up during operation due to various power losses. Oil takes heat away from the core and windings by the process of conduction and carries heat to the surrounding tank, which is then radiated out to the atmosphere. Viscosity, pour point, and flash point need to be maintained.

Finished 125 KVA 11/0.55KV Transformer

Transformer maintenance

At a minimum, monthly visual inspection of all bushings and other penetrations for oil leaks (pressure taps, sample taps, etc.) and oil level. Twice annual inspection of cooling fans to ensure they are working properly. At least annual oil testing and analysis to monitor the condition of the transformer, also annual testing of protective devices such as temperature relays, pressure switches, etc. Clean the top of the transformer and the primary bushings.

Packing and Delivery

Packing attention

Special attention shall be paid to the loading of the transformer when loading: due to the concentrated weight of the transformer, the concentrated load at the bottom of the ship shall be guaranteed when considering the barge to be carried, and reinforcement measures shall be taken if necessary; the bumping wave of the ship shall be taken into consideration in water transportation, and the binding must be firm.
