GYD Lightweight Dry-type Test Transformer
Product Introduction
The GYD lightweight dry-type test transformer utilizes advanced production equipment, adopting new processes of coil winding epoxy vacuum casting and CD-type iron core. Compared with similar oil-immersed transformers, it significantly reduces weight, decreases volume, improves insulation strength and moisture resistance in quality, and effectively weakens magnetic flux leakage, greatly enhancing the transformer's ability to withstand the impact of test short-circuit currents.
The dry-type test transformer is suitable for on-site testing of insulation performance of various electrical equipment in power systems and for various power users, as well as for high-voltage power sources in various voltage systems or devices requiring DC high voltage and small current for electrical products. It outputs AC and DC high voltage, providing high voltage for various high-voltage tests. The dry-type test transformer is used for on-site testing of insulation performance of various electrical equipment.
Our company participated in the formulation of the industry standard for test transformers, "DL/848.2~2004 General Technical Conditions for Power Frequency High-Voltage Test Devices"
