EUNSUNG Engineering

This is a switchgear with vibration-proof and anti-seismic features that protects electric facilities from earthquakes and prevents the secondary harms of the earthquakes, which are personal injuries and property damages, by installing spring modules that isolate vibration in high and low voltage switchgears and motor control center to secure the safety of electrical facilities during an earthquake

Switchgear equipped with vibration-proof and earthquake vibration absorption device

High-tension switchgear and low-tension switchgear

A device that receives electricity and converts it to match the purpose of use and the purpose of a facility

Motor control center and Integrated panel board

Devices that protect the operation and control for more stable and smooth operation of the motor

Specification

This is a customer-tailored device that puts safety first, reducing the installation area by up to 57% compared to conventional extra-high tension switchgears. As the MCSG that has the highest level of protection among air insulated closed switchgears, this is structured in an independent bus that prevents accidental impact on the adjacent switchgear.
