📝 Description
Used product.
Electrical busbar support spacer insulators belonging to the SM series, model SM-7110 with M8 threaded inserts.
These components are designed to support, secure and electrically insulate busbars inside low-voltage distribution panels, electrical cabinets and industrial equipment.
They feature red composite insulating bodies with a cylindrical shape and a central hexagonal section to facilitate tightening, together with integrated metal threaded inserts. The 7110 marking is visible on the upper part, consistent with the model indicated.
Insulators in this series are generally manufactured from glass-fibre-reinforced polyester resin, a BMC/SMC composite material selected for its insulating properties, mechanical strength and resistance to the stresses typically found in electrical installations.

🧱 Materials and Construction Features
The SM series is commonly manufactured from BMC/SMC composite material, consisting of thermosetting resin reinforced with glass fibre.
This type of material offers:
- Good electrical insulation properties.
- High rigidity and mechanical strength.
- Good dimensional stability.
- Resistance to mechanical stress and vibration.
-
Good thermal resistance compared with common plastic materials.
The construction includes a threaded metal insert, generally made of brass or steel, embedded in the insulating body.
🔧 Main Functions
- Supporting and insulating conductive busbars.
- Securing busbars inside electrical panels.
