Low-voltage high-current transformer
Product Overview:
Low-voltage, high-current transformers, produced over the years with selected materials and advanced technology in our company, feature moisture resistance and easy maintenance. They can be deeply embedded in load centers and are suitable for power transmission and distribution in places like subways, high-rise buildings, airports, stations, ports, enterprises, and tunnels.
Low-voltage, high-current transformers, primarily used for AC power supply at 50-60Hz frequencies, with voltages not exceeding 700V, are suitable for various power supply locations, product input/output voltages, connection groups, and tap winding capacity distribution. These can all be carefully designed and manufactured according to customer requirements.
