KEY BENEFITS
PROVEN APPLICATIONS
Compact design ideal for space-constrained projects in crowded cities and congested industrial zones.
Outstanding performance in harsh environments, including high altitude, heavily polluted, coastal, desert and arctic sites.
Low audible noise and electric field emissions make this product attractive for densely populated areas.
MODULAR DESIGN
Standard configurable modules allow reduced lead times for any customer arrangement.
Fully assembled, pressurized and tested in the factory.
Modules can be energized within 24 hours of delivery.
Significant cost savings over traditional GIS solutions.
SAFE, RELIABLE, AND LOW-MAINTENANCE
Grounded tank design is safe to touch.
Completely arc-resistant.
Modules connected with gas-tight flanges, delivering decades of reliable operation.
Modules individually configured and tested within an ISO 9001 factory environment.
Corrosion-free aluminum housings ensure safe encapsulation of factory-filled SF6 gas.
Simple gas filling requires top-up with SF6 bottles only; no complex gas processing equipment required.
Compact modules require no special shipping considerations.
The circuit breaker module is comprised of two interconnected structures: the stored-energy spring mechanism and the current interrupting unit.

CURRENT INTERRUPTING UNIT
Two separate current-carrying contact paths for each current interrupting unit; main contacts disconnect first and connect last to minimize arcing damage.
During a short circuit, arc-generated thermal pressure assists the spring operating mechanism to quickly pull contacts apart.
Arc-quenching design provides exceptional durability by minimizing mechanical stresses on circuit breaker components.
STORED-ENERGY SPRING MECHANISM
Provides force to efficiently and reliably open and close the circuit breaker.
Compact layout allows for straightforward viewing of spring mechanism position.
Sealed bearings and maintenance-free charging mechanism deliver decades of problem-free operation.

THREE POSITION SWITCH
Single three-position switching module incorporates both isolation and earthing functions.
Position indicators allow visual inspection of switch position.
SEALED THREE PHASE BUS
Sealed connection modules available in a variety of configurations to enable GIS arrangements according to any customer requirement.
Bellows-type expansion joints between modules mitigate the effect of temperature-related changes and allow for practical site assembly tolerances.
CURRENT AND POTENTIAL TRANSFORMERS
Current transformers and potential transformers provide key measurement and system protection functions.
Three-phase CT and PT modules can be positioned at any point within the GIS system.
Wide range of protection and metering classes available.
HIGH-SPEED EARTHING SWITCH
Maintenance-free electric motorspring mechanism delivers fast and reliable operation.
Arc-resistant contacts enable use in transmission line grounding applications.
LIGHTNING SURGE ARRESTORS
Provides protection from excessive voltages that may occur in case of a lightning strike or switching transient.
Online monitoring and surge-count with the use of integrated current sensors.
SF6 OUTDOOR BUSHINGS
Suitable for outdoor termination to overhead lines and transformer bushings.
CABLE TERMINAL UNITS
Allows for the connection of typical high-voltage cable types to the GIS system.
LOCAL CONTROL CABINET
Provides central control and monitoring of the GIS system, including operation control, signal collection, relay protection, and SF6 monitoring.

DOUBLE BUS LAYOUT
Critical load centers and power generation facilities commonly use a double bus GIS configuration. The two busbars can be operated separately or tied together. Double bus configurations can reduce the short circuit current, extend the standard maintenance period, and enhance power supply reliability.
