Single-phase isolating transformers, 1TTS type
Purpose and design
Single-phase isolating transformers are designed to supply small electrical appliances when voltage isolation is required. Isolation is achieved by the use of double-chambered coils or a copper screen between the windings. The standard design of the transformer provides fixing by means of angle brackets screwed to the core. Transformers may have several primary and secondary windings, and each winding may have additional voltage tap changers. The current terminals can be located on one or both sides of the transformer.
Note:
Upon agreement, we can manufacture a non- standard device with the required technical parameters.
The manufacturer reserves the right to make changes to the parameters due to technical product developments.
