Chopping Gap By Shanghai Jiu Zhi Electric Co., Ltd.

We manufacture a vast assortment of Chopping Gap to our clients in Yangzhou, Jiangsu, China.

chopping gap (LI chopped time 2~6us ) to test power transformers, instrument transformers and bushings.
chopping gap can be used for chopping of lightning impulse voltages between 20 kV and 3600 kV. The chopping can be realized at the front or at the tail of the impulse.
It serves simultaneously as a load capacitor for the impulse generator and allows excellent reproducibility of the chopping time and does not distort the wave shape until the chopping point. It is for indoor operation and mobile design.
