Product Details

■ Product Overview

Compared with traditional oil-immersed lightweight test transformers, the series of inflatable, partial-discharge‑free test transformers… , It has been made lighter in weight. 20-60%( Depending on the voltage and capacity ratings. ), Moreover, it is free from oil contamination, and the voltage rating of a single test transformer can reach 300kV . Thanks to the adoption of a new manufacturing process, the product’s technical performance has been significantly improved. , It is particularly well suited for fieldwork and applications involving frequent relocation.

■ Product Features

This instrument is compact and lightweight. ( Lighter than oil-immersed test transformers of the same class. 20%-60%);

Clean, free of oil and grease, maintenance-free. ;

Unaffected by adverse weather conditions, on-site handling allows testing to be conducted without requiring the equipment to remain stationary. ;

Its dielectric strength is significantly higher than that of oil-immersed test transformers, with minimal corona discharge.
