GOT series single-phase and three-phase isolation/autotransformers
Introduction
Our company specializes in the professional manufacturing of three-phase dry-type transformers ranging from 1 kVA to 2000 kVA, using high-quality materials and advanced manufacturing technologies. The products comply with international and national standards, including VDE 0550, IEC 439, J8555, and GB 5226.
The GOT Series three-phase dry-type transformers are widely used in various power supply applications with AC 50/60 Hz frequency and input/output voltages not exceeding 500 V. The input/output voltage levels, high/low voltage configuration, connection group, tap adjustment position, winding capacity allocation, secondary winding distribution, and whether an enclosure is required can all be carefully designed and manufactured according to user requirements.
This series of isolation transformers features excellent fire resistance, moisture resistance, high safety and reliability, energy-saving performance, and easy maintenance.
