TECHNOLOGY

LG HI-POWER VI2 switchgear using a Vacuum Circuit Breaker (VCB) is metal clad type in compliance with IEC/BS standards, and is designed for general power distribution systems with rated voltage up to 12kV.

COMPACT AND SIMPLE DESIGN

• Standard module for each circuit
• Human engineering for measuring and indication

SAFETY DESIGN

• Compartments are divided by grounded metal partitions.
• Quick-make earthling switches are used for earthling and withstand of making capacity.
• Type tested in accordance with IEC 298.
• Removable circuit breaker with mechanical interlocks to prevent mal-operation.
• Pressure relief device is available on request.

MAINTENANCE AND INSPECTION

• VCB is maintenance free.
• Minimized maintenance and simplified inspection work are realized, allowing easy and fast cable connection.
• Tightly sealed enclosure protects the equipment from ingress of contamination and vermin.

LG medium voltage vacuum contactors using LG vacuum interrupters manufactured with world class technology are type tested in LG PT & T that is accredited high power test lab by world class KOLAS.

Features

• The LG HRC Power Fuses belong to the PRIME MEC series. It interrupts high currents before the first loop of fault current has reached its natural peak value and therefore cuts down the required withstand capacity of the associated equipment on the electric system.
• Though small in size- it has a high breaking capacity and its enclosed type is suitable for use inside of the panel board.
• PRIME MLC fuses are equipped with striker pins for trip indicators as well as for operating the related load break switches.
• Link type fuse holder enables easy maintenance and high stability when replacing the fuses.
• With Fuse Checker, checking the conditions of a fuse in the panel board or bv telecommunication is possible.(Optional)

Applied standards

• IEC 282-I, DIN 43625, BS 2692, KSC 4612

Applications

• Transformer protection
  -To protect against short circuit current in the secondary part of a transformer and fault current in the transformer circuit.
• Condenser protection
  - To protect against fault current in the condenser circuit.
• Motor protection
  - To protect against fault current in the motor circuit
• Cable protection
  - Fault current protection secures the cable

• Small Size and Light Weight
• High performance, reliability, and long life are assured.
• Maintains High Vacuum
• High-alumina ceramics provide superior mechanical strength and easy degassing.
• High speed interruption and short arcing time.
• The LG Vacuum Interrupter can meet all IEC, ANSI and NEMA performance standards.
