Test transformers, also known as boosters, are essential equipment for testing the electrical strength of power generation and supply equipment, various electrical products, and insulation tool materials. The GYD series dry-type test transformers produced by Huayi Power have completely changed the outdated situation of bulky, large, and heavy test transformers. After being installed with the supporting high-voltage silicon stack, they can provide DC high-voltage test power, equipped with control boxes (platforms), automatic protection microamperes, ball gaps, and other ancillary equipment. They are particularly suitable for on-site testing, making heavy work convenient, fast, easy, and flexible, and greatly improving efficiency. Therefore, it is highly welcomed by high-voltage testing personnel in power systems and large factories and mines.
Dry type test transformer is a new type of product produced after extensive improvements on the basis of similar products. This series of products has the characteristics of small size, compact structure, complete functions, universality, and easy use. It is particularly suitable for conducting insulation strength tests on various high-voltage electrical equipment, electrical components, and insulation materials under power frequency DC high voltage in power systems, industrial and mining enterprises, scientific research departments, etc. It is an essential and important equipment in high-voltage testing.GYD series products, utilizing advanced production equipment, adopt coil winding epoxy vacuum casting and CD type iron core wound with high-quality cold-rolled silicon steel, effectively weakening magnetic leakageThe DC withstand voltage test does not require an external silicon stack. Simply install the DC high-voltage silicon stack provided by our company on the high-voltage end to obtain DC.
