RLK-10 Outdoor Rocking Type Disconnect Switch

Reliable Isolation for 10kV Distribution Networks

The RLK-10 Outdoor Rocking Type Disconnect Switch is designed for switching de-energized sections of medium-voltage power networks, providing visible isolation and safe maintenance operations. Featuring a rocking-type mechanism, polymer insulators, and a corrosion-resistant galvanized steel structure, the RLK-10 is widely used in overhead distribution lines, pole-mounted substations, and utility networks. It can also be equipped with earthing switches for enhanced operational safety.

Product Features

FAQ

What is the purpose of an RLK-10 disconnect switch?

The RLK-10 is used to isolate de-energized sections of medium-voltage power systems and provide a visible break for maintenance safety.

Can the RLK-10 interrupt load current?

Standard RLK-10 disconnectors are designed for no-load switching. Special arc-extinguishing versions can interrupt limited load currents.

Is a grounding switch available?

Yes. Versions with one-side or two-side earthing switches are available.

Can polymer insulators replace porcelain?

Yes. Polymer insulators provide lighter weight, better pollution resistance, and reduced maintenance requirements
