Transpower Switchgear Industries a dominant air break switch manufacturers, suppliers, traders and exporters in Mumbai. An Air Break Switch (ABS) 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 using air as the insulating medium, enabling it to break or make the circuit in an open-air environment. Mainly used in high-voltage systems, it is widely utilized in transmission and distribution networks ranging from 11kV to 36kV. Built from high-quality materials, it is specifically designed for outdoor installations. Below, we have detailed its different types, benefits, and applications!
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 leading air break switch manufacturers in Mumbai, we are providing multiple types of air break switch such as:
- 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.
- 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 switches for reducing power consumption and also installed GSM-based or IoT-enabled control systems for remote operations.
- 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 switches, we have used a polymer insulator for better weather resistance and durability. These are commonly used in rural and urban distribution networks to isolate faulty sections.
- 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 fit into modern types of substations and also uses smart sensors for live temperature and load monitoring. This can improve overall efficiency and is ideal for overhead transmission lines and industrial substations.
