Custom Switchgear Manufacturers

Switchgear, also referred to as switch gear, is an assembly of devices like circuit breakers, fuses, and relays used to control, protect, and isolate electrical equipment. It is essential for ensuring the safety and reliability of power distribution systems, especially in medium voltage switchgear applications.

Switchgear is available in three main categories: low voltage, medium voltage, and high voltage. Configurations such as metal-clad, pad-mounted, and air-insulated switchgear are designed to suit a variety of applications. Additionally, custom switchgear solutions can be developed to meet specific operational needs, providing flexibility and tailored features.

Low voltage switchgear is a type of electrical equipment used to manage, control, and protect electrical circuits operating at low voltage levels, typically up to 1,000 volts. It includes components such as circuit breakers, fuses, contactors, and disconnect switches. Low voltage switchgear is commonly used in residential, commercial, and industrial applications to ensure the safe and reliable distribution of electrical power.

Medium voltage switchgear is designed to handle electrical systems operating at voltages typically ranging from 1,000 volts (1 kV) to 36,000 volts (36 kV). It provides control, protection, and isolation of electrical equipment in substations, industrial facilities, and utility networks. Medium voltage switchgear includes components like circuit breakers, relays, and transformers, and it plays a critical role in maintaining the reliability and safety of medium-voltage power distribution systems.

Metal-clad switchgear is a type of switchgear where all major components, such as circuit breakers, relays, bus bars, and current transformers, are enclosed within metal compartments. Each component is housed in its own compartment to enhance safety, reliability, and ease of maintenance. Metal-clad switchgear is typically used in medium voltage applications, offering robust protection against arc faults, electrical shocks, and environmental conditions.

Pad-mounted switchgear is a type of switchgear designed for outdoor installation on a concrete pad. It is typically used in medium voltage distribution systems for underground power networks. Pad-mounted switchgear is fully enclosed and weatherproof (NEMA 3R or IP24), providing protection against environmental elements and unauthorized access. It is commonly found in utility, industrial, and commercial applications, offering reliability, compact design, and ease of operation.

Air-insulated switchgear (AIS) is a type of switchgear where air is used as the primary insulating medium to protect and separate electrical components. It is commonly used in medium voltage applications and consists of exposed bus bars and components within a protective enclosure. AIS is known for its simplicity, reliability, and ease of installation, making it suitable for indoor and outdoor use in substations and industrial facilities.

Switchgear consists of various components that work together to control, protect, and isolate electrical systems. Key components include: 

• Circuit Breakers: Protect the system by interrupting fault currents. 
• Disconnect Switches: Isolate sections of the electrical circuit for maintenance. 
• Fuses: Provide overcurrent protection by breaking the circuit when excessive current flows. 
• Bus Bars: Conduct and distribute electrical power. 
• Relays: Detect faults and initiate breaker operation. 
• Transformers: Step voltage levels up or down as required. 
• Current and Voltage Sensors: Monitor electrical parameters for protection and control. 
• Control Panels: Allow for manual and automated operation of the switchgear system.  
  

Custom switchgear allows users to address unique electrical and operational challenges. Designed by experienced switchgear manufacturers, custom switchgear offers a flexible footprint and seamless integration with existing systems, while still providing precise control and improved reliability.

Industries such as mining, manufacturing, commercial buildings, renewable energy, and water treatment rely on custom switchgear. Switchgear manufacturers in Canada offer tailored solutions to meet the needs of diverse sectors, ensuring efficient power distribution.  

Look for switchgear manufacturers with expertise in designing custom switchgear and proven experience with medium voltage switchgear. Manufacturers should also meet industry standards like CSA and IEC to ensure safety and performance.

Regular maintenance of switchgear involves inspecting components, testing relays, cleaning busbars, and replacing worn parts. Custom switchgear manufacturers often provide maintenance plans to extend the lifespan of the equipment.

High-quality custom switchgear should meet certifications such as CSA C22.2 for Canada or IEC 62271 internationally. Reputable switchgear manufacturers in Canada ensure compliance with these standards.
