Product Description

Product Description

KDZD power frequency withstand voltage test device is the most strict, effective and direct method to identify the insulation strength of power equipment. It can check out those dangerous centralized defects, and plays a decisive role in judging whether the power equipment can continue to participate in the operation. It is an important means to ensure the insulation level of equipment and avoid insulation accidents.
 
Kdgtb power frequency voltage withstand test device is an advanced voltage withstand test device designed according to the latest national power industry standards. It is used to test the insulation strength of various electrical products, electrical components, insulating materials, etc. under the specified voltage, so as to assess the insulation level of the product, find the insulation defects of the tested object, and measure the overvoltage capacity.
 
Kdgtb series withstand voltage transformers, using advanced production equipment, adopt the new process of epoxy vacuum casting of coil winding and CD type iron core. Compared with oil immersed transformers of similar products, they significantly reduce weight and volume, improve insulation strength and humidity resistance in quality, effectively weaken magnetic leakage and greatly enhance the impact ability of the transformer to withstand test short-circuit current.

Kdgtb dry-type series test transformer has the characteristics of light weight, small volume, beautiful appearance, stable performance, easy to use and carry. It is especially suitable for field operation. It is a new generation of AC and DC dual-purpose high-voltage test transformer in China. This series of products are applicable to the insulation performance test of various electrical equipment in the power system and various power users, and the high-voltage power supply in various voltage systems or devices with DC high-voltage and small current of electrical products.
