Cylindrical insulators

Cylindrical insulators – reliable insulation for demanding applications

Cylindrical insulators are durable and versatile insulating components used especially in electrical and industrial environments to separate conductive parts from each other. As their name suggests, they are cylindrical insulators that are well suited for applications such as busbars, switchgear, switchboards and various machine and equipment structures. The right cylindrical insulator improves system safety, extends component life and reduces maintenance requirements.

Cylindrical insulators are available in a variety of materials, including glass-fiber reinforced plastic, specialty plastics, and other materials with good electrical insulation properties. They are designed to withstand mechanical stress, temperature variations, and electrical loads. The insulators are also designed with mounting in mind: common solutions include threaded sleeves and bolted mountings, which allow for quick and reliable installation in various structures.

Typical applications for cylindrical insulators include electrical switchboards, distribution cabinets, industrial control and monitoring systems and various busbar solutions. Cylindrical insulators can be used to separate busbars from the frame or from each other at a safe distance and ensure that mechanical vibrations or thermal expansion do not weaken the insulation. Choosing the right size, material and load class ensures that the insulator can withstand both electrical and mechanical stresses over a long service life.

Our extensive range includes cylindrical insulators in various sizes, thread sizes, voltage and load ratings. If necessary, we can help you select the right products for your application – whether it's a new design project or the maintenance and upgrade of an existing system.
