Insulating Panel: Thickness 3-25 mm

Component Specifications

Definition

A rigid or semi-rigid panel designed to provide electrical insulation and thermal barrier protection between machine components, preventing electrical shock hazards and heat transfer in industrial equipment. Typically installed as part of isolation barriers in machinery where electrical components operate near conductive surfaces or where thermal management is critical.

Working Principle

Works by creating a physical barrier with high dielectric strength to block electrical current flow and low thermal conductivity to reduce heat transfer. The panel interrupts potential electrical paths and provides thermal resistance through its material properties and structural design.

Materials

Typically made from fiberglass-reinforced plastic (FRP), polycarbonate, phenolic resin composites, or ceramic-filled polymers. Materials must have dielectric strength >10 kV/mm, thermal conductivity <0.5 W/m·K, and flame-retardant properties (UL94 V-0 rating or equivalent).

Frequently Asked Questions

What is the primary function of an insulating panel in industrial machinery?

The primary function is to provide electrical isolation between live components and conductive machine parts to prevent electrical shock hazards, while also serving as a thermal barrier to manage heat transfer in equipment.

How do I select the right insulating panel for my application?

Consider the voltage rating required for electrical isolation, maximum operating temperature, mechanical strength needs, chemical resistance requirements, and compliance with relevant safety standards for your industry and region.

Can insulating panels be customized for specific machinery?

Yes, insulating panels can be custom-cut to specific dimensions, shapes, and thicknesses. Mounting holes, cutouts for components, and special edge treatments can be specified based on machine requirements.
