Gas Insulated
Switchgear
Hyundai Electric entered the circuit breaker market in 1984, and has maintained its position as a domestic leader in the field for the past 30 years, supplying its products to 40 countries worldwide.
Using the latest facilities and production systems in line withthe latest international standards, we have the capacity to produce Gas Insulated Switchgear up to 800 kV, the maximum rated voltage in Korea.
Due to their small installation space requirement and low-noise, low-electromagnetic radiation properties, our high-voltage circuit breakers are recognized for their high quality and enjoy a large market share in the Middle East, particularly Saudi Arabia.
