Electrical Isolator

KP Green Engineering Limited (previously known as KP Buildcon Pvt. Ltd.) is one of India's reputable electrical isolator manufacturers, supplying precision-engineered solutions for safe and effective power distribution. We develop electrical isolator switch systems designed to complete de-energization of electrical equipment during service or maintenance.

An electrical isolator is essential in substations and power networks to isolate a section of the circuit by disconnecting it from the system. This further assures safe working practices for the operator and no accidental energized condition. In technical terms, the isolator in a electrical system works as an offload disconnector, meaning it works only when there is no current flowing through the circuit.

Frequently Asked Questions

An electrical isolator is used to disconnect a portion of an electrical system, ensuring it is fully de-energized before maintenance or service.

An isolator switch is an offload device operated when no current flows, while a circuit breaker interrupts live current under fault or load conditions.

An isolator in electrical system is usually installed in substations and distribution networks, positioned after the circuit breaker to ensure complete isolation.

Yes. As one of the experienced electrical isolator suppliers in India, we can manufacture and configure isolators according to project-specific requirements.
