Air disconnect switch – reliable protection for power lines

The ONM III SA 24/4Ko air disconnect switch is a key element of electrical infrastructure, designed for the safe disconnection and grounding of overhead lines. The design of this device provides effective insulation and protection against short circuits, and its modular construction allows for flexible adaptation to different pole configurations. Made of durable materials, it guarantees long-lasting and trouble-free operation in demanding weather conditions.

Construction and application

The switch brackets are made of S235 steel, which ensures high mechanical strength and corrosion resistance thanks to hot-dip galvanizing. This device is widely used in mounting brackets for street lights on the tops of spun concrete poles. The modular construction allows for independent adjustment of the poles relative to each other, maintaining minimum insulation distances. This is particularly important when mounting on poles with non-standard dimensions.

Advantages and benefits

• Durable construction: The use of S235 steel and hot-dip galvanizing ensures corrosion resistance and long life.
• Modular construction: Allows for flexible adaptation to different pole configurations and easy installation.
• Safety: Effectively isolates and grounds overhead lines, protecting against short circuits and damage.
• Versatility: Designed for mounting brackets for street lights on spun concrete poles.
• Compatibility: Available versions with porcelain, composite or silicone insulators (including a version with composite insulators – Ko).
• Ease of integration: Possibility of mounting with surge arresters and support insulators.

The ONM III SA 24/4Ko disconnect switch is an ideal solution for both professional installers and end-users looking for a reliable and safe element of electrical infrastructure. Its solid construction and adaptability to various mounting conditions make it an investment for years to come.
