Electrical Isolator Manufacturers in Pune – Transpower Switchgear Industries
Transpower Switchgear Industries is one of the leading electrical isolator manufacturers, suppliers, traders, and exporters in Pune. We are providing high-quality and new technological electrical isolator which is mechanical device or switch used to completely disconnect a specific part of an electrical circuit from power source.
It also serves as a safety mechanism to ensure that the isolated section is entirely de-energized during maintenance and repairs. The primary function of these electrical isolators is to enhance manual safety by preventing any residual voltage or current in the isolated sections. They are widely used in industrial settings, substations, and electrical distribution systems to isolate equipment for servicing or repairs.
Types of Our Electrical Isolator
As a leading electrical isolator manufacturers in Pune and electrical isolator suppliers in Pune, we are offering new technological electrical isolator which gives the highest performance such as:
- Single Break Type Isolator: Our single break type isolator has only one break per phase and makes it simpler as compared to a double-break isolator. The isolator consists of a fixed and a moving contact that separate during the isolation process. It has a simpler design and fewer components and is suitable for use in medium to high-voltage systems. These are highly used in outdoor installations.
- Line Side Isolator: A Line Side Isolator is installed on the transmission line side to isolate the line from the substation for maintenance purposes. It prevents back-feed currents from entering the station when maintenance is in progress. These are placed at the entry or exit point of transmission lines and majorly used in high-voltage substations.
- Pantograph Type Isolator: A Pantograph Type Isolator has a unique design where the moving contact moves in a scissor-like manner (similar to a pantograph mechanism). This type is widely used in high-voltage substations and railways. It has a compact design and provides a clearer and more visible break and ensures fast operation with a minimum kind of effort. These are highly used in high-voltage transmission lines.
- Double Break Type Isolator: Our new technological double break type isolator has two types of breaking points in each phase and helps in enhancing safety and more reliability. It has three insulators such as two fixed and one moving. When the isolator is operated, the moving contact separates from the fixed contacts, ensuring a clear and visible disconnection. It is majorly used in transmission and distribution substations.
- Bus Side Isolator: A Bus Side Isolator is used to isolate a specific section of a busbar system in a substation. It ensures that maintenance can be performed safely on a particular bus section without affecting the entire power network. These are installed near busbars in substations and help in sectionalizing busbars for maintenance and are available in single or double break designs.
