Support Insulator K-711 Изолятор опорный (К-711)

The K-711  support insulator is widely used in low-voltage switchgear, power cabinets, busbar systems, and industrial electrical equipment.

It serves as a secure support point for copper and aluminum busbars while maintaining the required insulation distance from grounded metal structures

Reinforced insulators are used for fastening busbar holders and flat busbars in electrical devices with voltages up to 380V.

Permissible loads: bending – 1.8 kN, tensile – 3 kN.
