Low-voltage, high-current transformer
Product Overview:
Low-voltage, high-current transformers are produced by our company over the years with selected materials and advanced technology, featuring moisture-proofing and easy maintenance. They can penetrate deep into load centers and are suitable for power distribution in places such as subways, high-rise buildings, airports, stations, docks, enterprises, and tunnels.
Low-voltage, high-current transformers, mainly used for various power supply locations with alternating current of 50-60Hz and voltage not exceeding 700V, offer versatile solutions for various input and output voltage requirements, connection groups, and tap wire group capacities. They can all be meticulously designed and manufactured according to customer specifications.
