GN30-12 12kV Indoor Disconnect Switch - Rotary, High Voltage Isolator

Isolation Technology Evolution: The Advantages of Rotary Design
Traditionally, disconnect switches have had installation difficulties due to limited room available for their operation and installation processes. ABILKEEN has addressed these types of issues through their standout rotary contact blade design, which has allowed for better compliance with end users' and utilities' requirements for rotating the blade to obtain circuit isolation, rather than through the traditional vertical break type switch.

The solid design features a 3-phase common chassis with two sets of quality-gradeinsulators and contacts installed on top and bottom of the chassis. Rotating the contact blade allows the operator to effortlessly and securely open and close the circuit. The rotary motion creates a clear-cut and easily visible separation, and the reduced overall area that these two types of switches take up within the switchgear builds makes it an ideal option for compact indoor Metal Enclosed Switchgear .

Unstoppable Technical Performance
The ABILKEEN GN30-12 can withstand high levels of pressure. With 12kV of rated voltage; 630A of rated current; 50 Hz AC power systems. When it comes to providing adequate fault protection, the switch is exceptionally rugged with a rated short-time fault withstand current of 20kA for (4) seconds and a rated dynamic fault withstand current of 50kA.

In high-voltage installations, insulation and safety are vital; the GN30-12 is among the finest in terms of performance. The GN30-12 can withstand a 1-minute power frequency voltage of 42 kV between phases and 42kV phase-to-ground as well as 48 kV across the open break, and has a rated lightning impulse withstand voltage of 75 kV phase-to-phase and 85 kV across the isolating gap. Therefore, the GN30-12 is guaranteed to be safe for use during any transient surge conditions.

Customized Solutions for Many Different Types of Grids: GN30-12D Version
Staying aware of the evolution of today's power systems, ABILKEEN understands the need for multiple configuration options. For the additional safety requirements during repair work and maintenance, the GN30-12D variant provides a complete solution with a mechanical interlocked ground knife. The GN30-12D switches are based on the GN30-12 model; however, the GN30-12D includes an integral grounding knife. The downstream (load) side of the switch will safely ground when the isolator is open, providing an easily identifiable ground and therefore, the utmost safety for maintenance personnel, in compliance with international standards.

Created to Handle Difficult Indoor Settings
The ABILKEEN GN30-12 is not only a strong unit but also built to last. It was designed to operate effectively in extreme conditions while maintaining good reliability when operated at rated service conditions, which are as follows:

Altitude – It can be installed at any altitude up to 1000m (and can be de-rated for use at higher altitudes).

Temperature – The unit will successfully function in ambient air temperatures between -10°C and +40°C.

Humidity – The GN30-12 was built to operate under high humidity (95% relative humidity daily average).

Because of its compact and well-insulated design, the GN30-12 requires less time to install and adjust than traditional installations; therefore, less time is required from panel builders and integrators to complete commissioning on site.

What Makes ABILKEEN Stand Out for Your High Voltage Equipment?
With many brands of generic electrical components available in the marketplace, ABILKEEN is recognized as the brand synonymous with quality and innovation within the electrical industry. With the GN30-12 12kV Disconnect Switch, you are not only purchasing a component; you are investing in:

Space efficiency – A horizontal rotary design allows for more compact switchgear assemblies;

Reliable operation – Silver plated contacts and solid mechanical construction will deliver lasting electrical and mechanical performance; and

Versatile application – The GN30-12 12kVDisconnect Switch can be used as part of a High Voltage Switchgear (GG-1A and XGN17 enclosures) or as an independent isolation point.

Final Thoughts
The ABILKEEN GN30-12 3 Phase 12KV 630A Indoor High Voltage Isolating Disconnect Switch is the ideal combination of compact design and reliable high voltage. The GN30-12 is perfect for a modernization project for your existing substation or for a new power distribution center providing you with safety, efficiency, and performance that meet the demands of our modern electric infrastructure.
