Isolation switch is a switch device mainly used for isolating power supply, switching operation, connecting and cutting off small current circuits. It should be noted that it does not have arc extinguishing function, so it can only open and close circuits without load current, and cannot cut off load current and short-circuit current.

Electrical distribution networks require switching devices that allow sections of a circuit to be visibly isolated for maintenance, inspection, and operational control. Distribution type disconnect switches are widely used where a clearly identifiable open gap is required to confirm circuit isolation.
The Reacon 36kV Distribution Type Disconnect Switch is designed for visible line isolation in medium-voltage overhead networks. The switch provides a mechanical means of disconnecting energized sections when operated according to utility procedures and system requirements.
The product is commonly installed on utility poles, feeder lines, and distribution network switching locations.

Distribution feeder isolation
Utility line sectionalizing
Pole-mounted switching locations
Rural electrification projects
Network maintenance programs
Utility infrastructure upgrades
Unlike fuse cutouts that provide fault-current protection, a disconnect switch is primarily used to create a visible electrical separation point within the network.
Isolate feeder sections
Support maintenance activities
Improve operational flexibility
Provide visible confirmation of disconnection
Because of these functions, disconnect switches are commonly specified in utility distribution standards and operating procedures.

Q1: What is a 36kV disconnect switch used for?
A1: It is used to isolate sections of an electrical distribution network and provide a visible open point for maintenance activities.
Q2: How is it different from a fuse cutout?
A2: A disconnect switch provides isolation, while a fuse cutout primarily provides overcurrent protection.
Q3: Can it be installed on utility poles?
A3: Yes. It is commonly used in pole-mounted distribution applications.
Q4: What is visible isolation?
A4: Visible isolation means the open contacts can be visually confirmed, providing assurance that the circuit is disconnected.
Q5: Does Reacon provide customized configurations?
A5: Yes. Different ratings, mounting arrangements, and project-specific configurations can be supplied.
