HV Testing Transformer
Wuhan Sangao Electrical Test Installations Limit Co. (Sangao)
Inflatable Ultralight Non Partial Discharge Testing Transformer is a high-end testing transformer which firstly marketed in China by our company. The high-light characteristic of the equipment reflects the smallness in size, lighter in weight clean, oil-free, unnecessary static of field investigation, longer working life without maintenance and slightness in non-partial-discharge. It is used for the insulators' voltage-resistance testing.
