Non-excitation Tap Changer
We are , Liaoning Jinli, specialized in Transformer Tap Changer such as OLTC、Off Circuit Linear Tap Changer、Off Circuit Cylindrical Tap Changer etc with 30 years experiences. Non-excitation tap changer is applying for many type of transformer such as power transformer、distribution transformer and so on.
By today, we have sold our products all over the country and around worldwide market and established long term cooperation relationship with domestic companies “Zhixin Group”, “Tianwei Group”, “ABB Group”, “Xuji Group” and world famous Australian WILSON company, TRAFO Spain SL company, SGB-suit Group in Malaysia, Alfanar company in Saudi Arabia.
An efficient distribution grid has as little equipment as possible. This enables savings of both investment as operating expenses. Voltage regulation distribution transformers with linear tap changers help to improve the efficiency of grid sections. Using them can reduce the total number of secondary substations.
In some tap changers which are placed in secondary side of the transformer. This type of taping is used in step-up transformer where low voltage winding is in primary side and high voltage winding is in secondary side. It shows the tap changer circuit on secondary side with tap interval of 2.5 %. In some distribution transformers the tap changer resolution can be up to 1% for fine adjustments.
