Air Break Switch Manufacturers in Australia, Air Break Switches Australia
Air Break Switch Manufacturers in Australia, AB Switches/Air Break Switches Suppliers, Exporters
We are the top choice air break switch manufacturers in Australia suppliers, traders and exporters in Australia. An Air Break Switch (AB Switches) is a type of electrical switch used in high-voltage power systems to isolate or de-energize a part of the circuit for maintenance, safety or fault clearing.
It operates in the air as the insulating medium, meaning it breaks or makes the circuit in an open-air environment. These are basically used in high voltage systems and usually used in transmission and distribution networks up to (11kV to 36kV). It is made with high quality of materials for using them into outdoor installations. Below, we have listed down some types, its benefits and applications also!
Working Principle of Air Break Switch
- Operates by physically separating contacts in an open-air environment to interrupt the circuit.
- Arc formation occurs due to inductive current while opening the switch.
- Air extinguishes the arc as the contact gap increases.
- Can be operated manually or through a motorized mechanism.
- Ensures safe isolation of electrical power in transmission and distribution networks.
- Contact design and insulation distance play a crucial role in reliable operation.
- Commonly used for fault isolation, load switching, and maintenance safety.
Types of our Air Break Switch
As a trusted air break switch manufacturers in Australia, we are providing multiple types of air break switches at best Price & Quality Material such as:
- Single-Pole Air Break Switch: These are manually and automatically operated and designed to isolate a single phase in overhead power distributed lines. In these single pole air break switch, we have used polymer insulator for better weather resistance and durability. These are commonly used in rural and urban distribution networks to isolate faulty sections.
- Gang-Operated Air Break Switch: In our gang-operated air break switch, a three-phase switch that operates simultaneously across all phases and complete isolation in medium and high-voltage networks. We have used SF6 gas assisted or vacuum interrupters that can reduce any kind of maintenance cost. For getting detailed information, we have used IoT-enabled switches for predictive maintenance and grid analytics. These are used in high-voltage substations to control multiple lines simultaneously.
- Air Break Switch (General Category): The air break switch is a high-voltage switch used in power distribution to interrupt circuit flow by physically separating contacts in open air. It comes in compact designs to into modern types of substations and also used smart sensors for live temperature and load monitoring. This can improves overall efficiency and ideal for overhead transmission lines and industrial substations.
- Motorized Air Break Switch: Our new advanced types of motorized air break are an advanced air break switch equipped with a motorized mechanism for remote operation and automated grid control. We have used energy-efficient motors in these air break switch for reducing power consumption and also installed GSM-based or IoT-enabled control systems for remote operations.
