Dry Type AC and DC Test Transformer

This AC test transformer adopts advanced new technology of coil winding, epoxy vacuum pouring and CD-type iron core, which obviously reduce weight and volume, improve insulating strength and humidity resistance level.
The transformers have light weight, small volume, beautiful appearance, stable performance and convenient operation, which are especially suitable for onsite operation. The transformers are applicable for the power systems and all power users to detect on site the insulating performance test of all electrical equipment. The transformers can be used as the perfect high voltage power sources of all appliance's voltage system.
