Air Break Switch Manufacturers in Australia, AB Switches/Air Break
Switches Suppliers, Exporters
We are the dominant 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 former 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.
