Air Insulated Switchgear (AIS) is an essential component of medium voltage electrical distribution, particularly for secondary distribution networks, and is typically designed in the range of 12 kV to 36 kV.

• Air insulation: Using air-insulated technology as the primary insulation medium between live components, these well-known MV switchboards have field-proven designs for peace of mind, by simplifying the design and maintenance process.
• Modular Design:Features a modular structure that allows easy customization, expansion, and integration of additional units as needed.
• Safety and Reliability:Designed with high safety standards, including arc resistance and advanced protection devices to protect operators and equipment from overvoltage and short circuits.

Secondary AIS switchgears are generally cost effective, environment friendly, flexible and scalable.

Our latest Secondary AIS switchgears are a perfect fit for a wide range of environments and applications, including industrial facilities, large and commercial buildings, power generation and smart grid.

Components are easily accessible, facilitating quick and efficient maintenance operations. The latest IoT-connected features bring predictive maintenance possibilities to maximize efficiency and minimize downtime.

Secondary AIS switchgear includes the following components:

• Circuit breakers: Vacuum or SF6-free technology for interrupting fault currents.
• Disconnectors and Earthing Switches: Provide safe isolation and grounding of circuits during maintenance.
• Instrument Transformers: Measure and monitor electrical parameters such as current and voltage.
• Protection Relays: Detect faults and control circuit breakers to protect the network from damage.
