Colours and shapes are not product specifications.From sheet to finished insulating component
Materials for your own machining or finished components made to drawings.
These components are supplied on request and are not standard stock items. Material grade, dimensions, quantity and lead time are agreed for each project.
Insulating sheets and packing pieces
For partitions, packing pieces, supports and contact surfaces between structural components.
Insulating washers
For bolted joints and fixings where the washer must provide electrical insulation and distribute the load.
Insulating sleeves and bushings
For bolt holes, penetrations and other details requiring a tailored insulating geometry.
Machined insulating components
Spacers, supports and custom parts with hole patterns, cut-outs and contours tailored to the design.
Colours and shapes are not product specifications.

GPO-3
Glass-reinforced polyester laminate for electrical insulation. We supply sheets that can be machined into components. Check flame and arc properties against the data sheet for the selected grade.
G-10
Glass cloth and epoxy combined in a laminate for mechanical and electrical applications. Assess the material against loads, moisture and insulation requirements.
G-11
An epoxy glass laminate for demanding technical components. Temperature and loading requirements must be assessed against documented product properties.
FR-4
An epoxy glass laminate that can be considered where flame performance is required. Confirm the appropriate grade and documentation before selecting the material.

Typical applications
- Electrical panels and partitions
- Transformers and electromechanical equipment
- Insulating supports
- Spacers and bushings
- Galvanic separation
- Technical structural components
Galvanic separation between metals
Galvanic corrosion can occur when dissimilar metals are in electrical contact in a damp or saline environment. Insulating packing pieces, washers and sleeves can form part of solutions that reduce the risk, for example in joints between steel and aluminium.
The entire joint must be assessed to achieve electrical separation. An insulating packing piece alone is not sufficient if bolts or other components still create a conductive path. Material selection, fixings, loads and drainage must therefore be considered together.
Which material fits your application?
Electrical and mechanical requirements
Specify the function, electrical requirements, loads and fixing method. Material data alone does not establish the performance of the complete installation.
Operating environment
Assess temperature, moisture and chemical exposure together. Properties of one grade must not be assumed to apply to all laminates.
Fabrication and documentation
Send dimensions, tolerances and machining requirements. Clarify any flame-performance requirements and product-specific data sheets before ordering.
From sheet to finished component
Our supply range includes materials and components from Dielettrika Ligure in Italy.
We can assist with cutting, drilling, milling and CNC machining to drawings. Sheets and laminates can be fabricated into insulating supports, partitions, bushings and spacers. Material, geometry and tolerances are agreed before the component is manufactured.
Rods, threaded rods, nuts and washers can form part of the delivery where the selected material and construction meet the requirements. Components are assessed against drawings and specifications.
Technical documentation
Request a data sheet for the specific material grade and size. Electrical properties, flame performance and other requirements must be checked against documentation for the product to be supplied.
