UniSafe 2.0 switchgear features
• The air insulation of all live parts plays a vital role in ensuring operational safety and durability.
• Meeting the highest industry standards, the system is classified under LSC-2B/PM.
• In addition, the apparatus set includes various components such as vacuum circuit breakers, SF6 circuit breakers, and vacuum contactors.
To enhance user safety, the apparatus can be racked in or out with the door closed. Additionally, the system boasts an internal arc classification IAC AFLR and is fitted with advanced safety interlocks.
Whether wall-mounted or free-standing, this solution offers flexibility. Putting the system into service, performing maintenance, and managing operations are conveniently carried out from the front.
For users seeking customization, high customization versions are available. The construction utilizes pregalvanized sheets without welding points, ensuring strength and reliability.
Moreover, a wide range of functional units accommodates diverse installation needs. Traditional CTs, VTs (both fixed and withdrawable), and sensors are also included. The modular structure is designed for easy assembly, simplifying the installation process.
