The Wöhner 05789 is a heavy-duty stand-off insulator designed to provide exceptional electrical insulation and mechanical support for low voltage switchgear, busbar systems and industrial control panels. Featuring M10 female threads on both sides and a 60 mm height, it is ideal for applications requiring increased electrical clearance and robust support for busbars and electrical components.
Manufactured by Wöhner, the 05789 insulator is produced from a durable halogen-free insulating material and is designed for demanding industrial environments. Its high dielectric strength, excellent mechanical performance and compliance with IEC standards make it an ideal choice for panel builders, OEMs and electrical engineers.
With a rated insulation voltage of 3000 V AC, 3.6 kV DC, M10 female threads and a 40 mm width across flats, the Wöhner 05789 delivers reliable insulation and mechanical stability for industrial power distribution and busbar support applications.
Stand-off insulators provide secure separation between live conductors and grounded metalwork while supporting heavy electrical components. They help maintain safe electrical clearances, improve installation safety and maximise the long-term reliability of switchgear and power distribution equipment.
The Wöhner 05789 is engineered for professional electrical installations where increased insulation distances, dependable mechanical performance and long service life are essential.
