Main Parts of Interrupter
A : Nozzle & Arcing Contact
Arc Quenching is carried out under highly-pressured SF6 gas compressed by Puffer System.
The excellent endurance anti-arc performance and simple structure of interrupter enable it to interrupt the rated peak
currents more than 20 times.
B : Main Contact
The stationary & moving contacts consisting of single body structure assembly reduces the number of parts and make
maintenance & inspection simple.

Interrupter
The interrupter of the HICO Gas Circuit Breaker has high
reliability for all interrupting duties and satisfies the latest
standards of IEC and IEEE.
Arc quenching takes place under 71PSIG of SF6 gas pressure.
Superior Mechanical Endurance
Mechanical endurance is demonstrated by life test of 10,000
operations.
The HICO pneumatic operating mechanism has been
demonstrated to have high reliability for over 20 years in all
types of climates and conditions.
Adopting SINGLE PUFFER System reduces thenumber of parts and makes the interrupter
simple and reliable.
Closing resistor can be provided initially andremoved as requirements change.
Operating Mechanism
Operating mechanism of the 362kV GCB is of the pneumatic type with proven capability and reliable operation history.
It satisfies the operating duty O-0.3s-CO-3m-CO required by IEC and IEEE.
It is designed and manufactured to interrupt in less than two cycles.
Interrupter is opened using compressed air and is closed using energy stored in coil-spring charged by open operation.
It can be opened and closed manually and safely by using a simple jacking system.

HICO SF6 Gas Circuit Breaker 10/11
Installation and Maintenance
All Circuit Breakers are designed, built, and tested in accordance with
the latest versions of ANSI & IEEE Standards C37.04, C37.06, C37.09.
HICO seeks to exceed all established testing criteria by carrying out
additional tests we consider essential in producing a higher reliabilityproduct.
Testing Laboratory
1. Professional maintenance system ensures life-long reliability.
2. HICOs comprehensive service offerings, prompt response time and
efficient & professional support are in place around the clock all
around the world.
3. Following factory assembly and testing, the Gas Circuit Breaker is
disassembled for packing and shipment.
4. All breakers supplied to North American sites are inspected,
assembled, and tested at HICO Americas U.S. facility.
Where possible, breakers are shipped assembled on conventional
low-bed trucks to the customers site.
HICO America also provides installation assistance and field
support.
The equipment is designed to minimize the number of disassembled
parts, while considering performance, maintenance, ease of
installation and transportation. The disassembled parts are packed as
complete units whenever possible to lower the construction costs at
the sites.
To maintain the highest criteria of operating reliability, a routine
inspection and maintenance schedule may be recommended.
Routine Inspection and Maintenance Schedule
