Air-Insulated Switchgear (AIS) – Rugged, Reliable Medium Voltage Solutions
In demanding industrial and utility environments, Air-Insulated Switchgear (AIS) remains one of the most trusted and long-lasting electrical distribution solutions. BECO, Symbol of Distinction, offers the AIS Fixeded series, engineered for 12 to 36 kV applications in compliance with IEC 62271-200 and IEC 61439 standards.
Our AIS Fixeded panels are specifically designed for rugged, maintenance-optimized performance, making them ideal for utilities, cement plants, and large industrial zones. With short-circuit handling capacity of 25–40 kA, these switchgear units deliver uncompromised safety and reliability under fault conditions.
The design incorporates monobloc epoxy resin insulation, enhancing dielectric strength, mechanical robustness, and resistance to environmental stress. A spring-operated mechanism ensures smooth, reliable operation of switching devices while reducing mechanical wear—making the solution maintenance-friendly and long-lasting.
Suitably rated at IP54, the AIS Fixeded system provides dependable protection against dust and water ingress, enabling both indoor and outdoor installation. When compared to competitors, our design allows for 30% faster installation times and notably lower maintenance costs over the operational life of the equipment.
For mission-critical MV power distribution, BECO AIS Fixeded offers the perfect balance of durability, flexibility, and cost-effectiveness.

Technical Excellence – Built for Industry Demands
Every AIS Fixeded switchgear unit is crafted to meet or exceed international performance and safety requirements.
Technical Specifications:
- Voltage Range: 12–36 kV
- Standards: IEC 62271-200, IEC 61439
- Short-Circuit Current: 25–40 kA
- Enclosure Protection: IP54 (indoor & outdoor capable)
- Key Features: Monobloc epoxy resin insulation, spring-operated mechanism
- Industries: Utilities, Cement Plants, Industrial Zones
The high dielectric strength and mechanical endurance of epoxy resin provide outstanding insulation reliability, even in high humidity or dust-prone environments typical in cement production facilities and industrial substations.
Short-circuit withstand capabilities of 25–40 kA ensure operational safety for heavy industrial loads, while standardized spring-charged mechanisms allow operators to perform controlled switching operations with minimal physical strain.
By sticking to stringent IEC certification requirements, BECO guarantees that AIS Fixeded switchgear delivers global-standard compliance, allowing integration into internationally operated projects.
Durability and Low Maintenance Costs
Long-term maintainability is a major cost factor for medium voltage equipment. BECO’s AIS Fixeded has been designed with both accessibility and service life in mind—reducing downtime and repair costs for operators.
Maintenance advantages include:
- Monobloc epoxy resin design – eliminates issues with moisture absorption and partial discharges.
- Fewer mechanical parts – spring-operated mechanisms reduce complexity.
- Easy inspection points – accessible compartments for quick servicing.
These features, combined with IP54 protection, ensure extended operational lifespans in dust-heavy industrial zones and outdoor utility installations.
According to customer installation data, maintenance cycles are 25–30% more cost-effective with AIS Fixeded compared to competing systems—making it a clear choice for long-term infrastructure planning.
30% Faster Installation – Competitive Advantage
Time is a critical cost factor in large-scale electrical projects. BECO AIS Fixeded systems are designed for streamlined installation and commissioning, ensuring projects meet aggressive timelines without compromising quality.
Reasons for faster deployment:
- Modular, factory-tested units ready for on-site connection.
- Simplified busbar and cable terminations.
- Standardized footprint and mounting arrangements.
For contractors and EPCs (Engineering, Procurement, and Construction companies), this 30% reduction in installation time translates to substantial savings in labor costs, reduced project overhead, and earlier revenue generation for utility and industrial operators.
When combined with BECO’s technical support and commissioning service, AIS Fixeded becomes a turnkey MV switchgear solution—reducing risk, time, and lifecycle cost.
Applications – From Utilities to Heavy Industry
The AIS Fixeded series is particularly well-suited to medium voltage power distribution in:
- Utility substations – delivering reliable distribution for grid operators.
- Cement plants – operating in abrasive, dusty environments.
- Industrial zones – supplying power to multiple heavy-load facilities.
With BECO, Symbol of Distinction, clients benefit from tailored engineering—ensuring the AIS switchgear not only meets technical requirements but also matches environmental and operational constraints at the installation site.
