and developed by our company. It applies to on load capacity & voltage regulating transformer.
According to customer's request, it is available to add permanent magnetic control mechanism and online oil
filter system.
On load capacity & voltage regulating tap changer SYTXY4-630(200)/10-5~7 60A /550A
On load capacity & voltage regulating tap changer
Product introduction
On load capacity & voltage regulating tap changer is patented product which is independently researched
and developed by our company. It applies to on load capacity & voltage regulating transformer. This is the
first time to use series multiple fracture in such tap changer which ensures to adjust the transformer capacity
and voltage under on load condition. The advances are reliable operation, long service life and etc..
According to customer's request, it is available to add permanent magnetic control mechanism and online oil
filter system.
For example, SYTXYL4-315 (100)/10-7V YC represents an online oil filter type three-phase on load capacity regulating star/delta conversion tap changer, with a rated capacity of 315KVA
(100KVA for star connection), rated voltage of 10KV (high voltage side), voltage level tap of 7V, equipped with permanent magnet control mechanism.
