Support Insulators

Support insulators provide insulating support and positioning for busbars or equipment parts. Selection combines mechanical loading, mounting connections and insulation layout. Appearance or a model number alone cannot establish suitability for a particular support arrangement.

152 Support Insulator

The 152 support insulator provides internal insulating support, with mounting faces, threaded inserts, actual height and mechanical loads checked for the application.

192 Support Insulator

The 192 support insulator serves equipment support and insulation arrangements, with end connections, load direction and electrical clearances assessed together.

200 Support Insulator

The 200 support insulator supports an insulated arrangement of conductive equipment parts, with end connections and mechanical loading checked for the application.

220 Support Insulator

An insulating support for busbar or internal equipment arrangements, selected by installed height, threads, creepage and mechanical loading.

252 Support Insulator

The 252 support insulator provides internal insulating support, with its mounting connections and mechanical duty selected from the specific product drawing.

Define the support duty

Busbar orientation, connections and support spacing affect loading. Describe load directions and equipment layout so bending, tensile or compressive requirements can be assessed against the installation. A load value without direction and mounting context is insufficient.

Load direction and point of application
End faces and threaded-insert connections

Review dimensions and insulation together

Height, creepage path and air clearance are separate considerations. Model numbers do not replace dimensioned drawings, and a longer outline does not automatically establish suitability for pollution or outdoor exposure. Assess environment and insulation requirements with the specific construction.

Spacing between mounting faces and hole tolerances
Creepage path and clearances to live parts
Equipment environment and insulation requirements

Keep support and conductor selection distinct

A purely insulating support does not independently carry current. Define the insulating body, metal inserts and fixing hardware supplied. If an assembly includes a conductive path, identify its conductor and connections separately before assessing current requirements.

Mechanical and insulation evidence for the version

Can a support be replaced by matching height alone?

Also check threads, mounting faces, mechanical loads and insulation layout. Height is only one matching condition.

Does a support insulator need a current rating?

Select a purely supporting part by mechanical and insulation requirements. For a conductive assembly, assign current requirements to the identified conductive components.
