 Vacuum Circuit Breaker, VCB is installed in the medium voltage distribution
lines to protect life and load equipment. In case of accidents such as over
current, short circuit and ground fault current, VCB works by interrupting the
circuit through the inner Vacuum Interrupter which is acted by signal from the
outside separate relay.

LSIS' Super Solution, Susol VCB responds.

- customer needs for the breakers with high interrupting capacity and large
current due to the integration and increase of the load capacity.
- worldwide trend of diversification in the medium voltage distribution lines.
- increase of the reliability for the temperature characteristics of circuit
breakers.

Premium-type products to improve convenience and reliability of medium

voltage switchgear configuration.
- full line-up modeling to the high interrupting capacity and large current.
- main structure with high reliability application.
- a variety of accessories and ability to maximize.

Safety considerations
This Solution Power switchgear provides the best protection rating out of Air Insulated Switchgear !!
Designed to remove explosion or damage to peripheral devices as possible in the event of internal arc happening
.To prove its reliability and safety LSIS use the internationally recognized testing agency, KERI / KEMA / CESI for
certification as well as LSIS' test lab PT&T that is a KOLAS-qualified (Korea Laboratory Accreditation Scheme)
accredited testing laboratory and provides worldwide testing service.

•Metal clad type: each compartment is divided by metal partitions for the highest degree of protection rating out
of Air Insulated Switchgears.
•Short-circuit, short-time current and internal arc tests passed at KERI / KEMA / CESI by IEC 62271-200.
•Various options including
- Mechanical interlock to prevent from inadvertent operating
- Mechanism enable the breaker to be drawn in or out without opening the door
- Position padlock to lock the breaker at the present position.
•Solid structure with hinge and locker
•IP Cover on the face of the breaker and inspection window on the door
•Metal shutter and shutter padlock installed in CB compartment for safe maintenance
•Used reliable tube & boots for busbar insulation
•Insulation cap and padlock used for earthing switch to secure insulation and safety
•CT equipped with protective insulation wall
•Inhouse test equipment with 1,500 MVA capacity for performing reliability test

 Convenient maintenance and inspection
Preventive maintenance is essential for all switchgears.
LSIS' One-Stop Total preventive maintenance activities cover continuous maintenance, inspection, remaining life
expectancy and streamline. Solution Power Switchgear is structured for these convenient maintenance and
inspection.

•Using recently developed Susol VCB for almost unnecessary maintenance and inspection .
•Low voltage compartment provides enough space to test and change the internal wiring easily, and the wiring
duct at the top of it is made of steel material .
•Independent bus compartment structured not to affect any accident to adjacent panels .

Digital type switchgear capable of digital data link

Digital Protection & Monitoring Device, GIPAM developed by LSIS is adopt for establishing convenient and reliable
