Product Description

Introduction
This type of tap changer is comprised by electric, drive me chanism, tap changer body and electric controller with two kinds of specifications standing type and horizontal type it is suitable for oil-immersed furnace transformer with rated voltage 40kV and below, rated current 630A and below. They must be working under non-energized condition. It can be operated by electric driver or handle drive.

Features of Round Type Electrical Device
(1) Transformer cover's round installation opening is smaller and power balance, so its sealing function is better than that of the square's.
(2) Reduce the complex components will make the structure more compact and enable high transmission reliability.
(3) The round electric operates freely and steadily with a high quality of gear shift and small noise.
(4) Round Series electrical device's voltage regulating can reach 30 grades and above which leave more space for transformer designing. It's superior to the others.
(5) This patent round electrical switch is in simple structure, advanced function and lower costs. It is economical and safe.
