Product Description

 22kv 630kva Resin-insulated Dry-type  Power Transformer

To improve the quality of electricity supply, we can conduct on-load voltage regulation if the dry-type transformer equips an on-load tapping switch. The on-load tapping switch equips an automatic controller, which facilitates the field control or remote control. Computer interface is provided as required by customers.

- Resin-insulated dry-type on-load regulating transformer usually adopts vacuum on-load tapping switch, which can be installed independently on the right(left) side of transformer or the front face of high voltage side.

- Complex on-load tapping switch (air type)is also available to meet the customer's need. This kind of tapping switch is installed on the main body, so it possesses the advantages such as compact structure, less area occupation and easy installation.

- Other kinds of on-load tapping switches are also available if needed.

- Isochronous controller is necessary if parallel running is adopted by several dry-type on-load regulating transformers, and the number of transformers should be no more than 4.
