📋 Description
Used product. Electrical busbar support spacer insulator featuring a hexagonal insulating body and two female M6 threaded metal inserts, incorporated at both ends. This component is used for the mechanical support and electrical insulation of busbars inside electrical panels, transformers and power distribution systems.
The component has a red-orange insulating body, with cylindrical ends and a central hexagonal section that facilitates tightening during installation. The metal inserts allow fastening with screws, providing a mechanical connection between the parts being supported.
Its shape and construction are consistent with low-voltage spacer insulators available in specialist manufacturers' catalogues, including ERIM, which manufactures insulators from glass-fibre-reinforced polyester compound. As no identification code or legible brand name is visible on the component, it is not possible to confirm that this item was manufactured by ERIM or that it exactly corresponds to model DB 25/P.
🏭 Applications
- Mechanical support and insulation of copper and aluminium busbars.
- Industrial and power distribution electrical panels.
- Electrical power distribution systems.
- Control and command panels.
- Electrical enclosures and cabinets.
- Transformers and electrical equipment.
- Fastening and spacing of conductive components.
