SFZ9-35kV on load oil-immersed power transformer

Introduce:

SFZ9-35kV on load oil-immersed power transformer is manufactured in conformity with the International Electrotechnical Commission standard IEC60076 and PRC National Standard GB1094.1.2-1996, GB1094.3.5-2003, frequency of 50 Hz, and they can be used as the power transmission and transformation of power grid for various industries.

Feature:
The iron core is processed by advanced longitudinal and transverse shear and restack equipment, and the stepped three-level joint distributes the air gap distribution, improves the flux trend, and reduces no-load loss, no-load current and noise
The core adopts special adhesive for drawing plate, pressing ring, silicon steel end face and a series of integral structure and measures to improve the mechanical strength
New structure of high and low voltage winding, reasonable layout of tapping area and oil channel design, improve mechanical strength and short-circuit resistance
The tank is bell type or hanging core type structure, the tank wall is corrugated, the box body line is smooth, simple, generous and beautiful

What is the function of high voltage voltage transformer

High voltage transformer is a transformer suitable for converting large voltage into small voltage or converting large current into small current in 1kv to 220kv power system for measurement, protection and use.

Generally divided into 3kv, 6kv, 10kv, 35kv, 66kv, 110kv, 220kv, and the 24kv system is being tested in Jiangsu. Among them, 10kv and 220kv are widely used. The secondary input is mostly 200V or 100V or 5A or 1A.
