TQSW Power Frequency Non Partial Discharge Test Transformer

I. Overview
In order to adapt to different voltage levels and capacities of power equipment for power frequency voltage testing, our company manufactures various specifications ofTQSW series power frequency non partial discharge test transformerUsers can choose according to their own needs.
TQSW series power frequency test transformerIt is divided into iron shell type and insulation cylinder type, which are respectively single-stage and series type. The iron shell type is suitable for situations with low local discharge requirements, the insulated cylinder type is suitable for situations with high local discharge requirements, the single-stage type is suitable for situations with low voltage and large capacity, and the series type is suitable for situations with high or low voltage, small capacity, and easy portability.
