High-speed rail/armored vehicle/naval vessel/large aircraft and other large transport vehicles have large DC load capacity and high reliability requirements.

High-speed railway, armored vehicles, warships, large aircraft and other fields require high switching load capacity and safety and reliability of DC relays. It is required that DC relay must have advanced technology in design and technology, and its performance is extremely reliable and consistent.

The high-voltage direct current relay developed by the company, especially the kilovolt-kiloampere series high-voltage direct current relay, has large load capacity and reliability. High characteristics ensure the safe operation of large transport system.
