Product Specification

basic wiring diagram:A
Numbers of service position:7
Rated. service voltage of tap-changer:35KV
Max.rated through current of tap changer:200A
Phases of tap changer:III

Product Description

This series on load tap changer applies to the oil immersed type power transformer or industrial transformer with rate voltage *0 kV, *5kV, Mac. rated through current **5A, **0A, **0A, rated frequeny *0Hz to change the tap connection postition change ratio of voltage regulation coil under load, in order to achieve the aim of improving electric energy quality.
On load tap changer work with YK*2, YK*3 controller and can realize the hand operation, automatic operation and remote control of on load tap changer.

Note:
Regulating method:A(neutral point liner regulating, without neutral point output); A1(neutral point liner regulating with neutral point output); B(middle part cross over)
There are several models of simply tyoe on load tap changer as follows:
**5A neutral point regulating: ZSIII********-A
**0A neutral point regulating: ZSIII********-A
**0A cross over regulating: ZSIII********-B
**0A neutral point regulating: ZSIII********-A
**0A cross over regulating: ZSIII********-B
**0A cross over regulating: ZSIII********-B
