Air disconnect switch - earthing, frame-type - horizontal 100A RUN III SA 24/4/100 03-704

Aerial disconnect-earthing switch – reliable network protection

This frame disconnect-earthing switch, with a rated current of 100A, is a key element of electrical infrastructure. It is used to safely disconnect and ground sections of overhead networks during maintenance or emergency work. The horizontal design makes installation simple and convenient, and the solid construction guarantees long-lasting and trouble-free operation. This device finds application in both medium voltage distribution networks and transformer stations.

Construction and application

The RUN III SA 24/4/100 disconnect-earthing switch is a three-pole device designed for operation in 24 kV systems. The designation "SA" indicates the use of porcelain insulators – a standard solution providing good electrical insulation and mechanical strength. The possibility of using composite or silicone insulators (in versions marked "K" or "S" respectively) allows the device to be adapted to specific environmental conditions and customer requirements. The frame construction ensures stability and ease of mounting on poles.

This device is intended for:

• Safely disconnecting energized circuits.
• Grounding disconnected sections of the network to ensure safety during work.
• Isolating damaged sections of the network to limit the effects of failures.
• Cooperation with surge arresters (in versions with appropriate design).

Key features and benefits

• Durable construction: The frame design provides stability and resistance to weather conditions.
• Versatility: The ability to use different types of insulators (porcelain, composite, silicone) allows adaptation to specific needs.
• Safety: Provides effective disconnection and grounding of circuits, minimizing the risk of electric shock during maintenance work.
• Simple installation: The horizontal design facilitates installation on poles.
• Compliance with standards: The device meets the required safety and quality standards, confirming its reliability.
• Modularity: Modular versions (OUNM III SA 24/4) are available, allowing flexible configuration of the switchgear arrangement according to network needs.
• Availability of spare parts: ALPAR as a manufacturer ensures the availability of spare parts, which facilitates servicing and repairs of the device.

This is a solid solution for professionals involved in the construction and maintenance of electrical networks and for investors who care about the safety and reliability of their installations.
