📋 Description
Used product. Lot of 10 hexagonal electrical support and spacer insulators, designed to support and secure busbars inside electrical panels, substations and industrial equipment.
The component features a red cylindrical body with a central hexagonal section and two M8 female threaded metal inserts, one at each end. The hexagonal shape provides a firm grip with a wrench during installation and tightening.
In terms of construction, it belongs to the family of busbar support spacer insulators used in electrical distribution systems. A comparable official reference is the DB series by manufacturer ERIM, which uses glass-fibre-reinforced polyester bodies and metal inserts. Since the brand of the photographed component cannot be identified, no product code, certifications or specific performance ratings from that manufacturer are attributed to the item being sold.
🏭 Applications
- Industrial and power distribution electrical panels.
- Support and spacing of copper and aluminium busbars.
- Electrical substations and transformers.
- Power centres and distribution equipment.
- Insulating support and fastening systems for electrical installations.

🧱 Materials and Construction Features
The exact material of the photographed component cannot be identified with certainty. As a reference, ERIM's official documentation for its DB series insulators specifies:
-
Body made of BMC RF 3/20 polyester compound, reinforced with glass fibres.
-
Metal inserts made of zinc-plated steel.
-
Stated operating temperature for the series: -40 °C / +130 °C.
-
Stated fire behaviour classification: UL94-V0.
These characteristics refer to the documented ERIM products and do not constitute certification of the component being sold.
⚡ Voltage and Insulation Values
The manufacturer's official documentation for the comparable ERIM DB 50/P model states:
-
Operating voltage: 2000 V.
-
AC surface flashover voltage: 12 kV.
-
AC internal flashover voltage: 40 kV.
-
Operating temperature: -40 °C / +130 °C.
-
Fire behaviour classification: UL94-V0.
-
HL2 classification according to EN 45545-2.
Please note: these data refer to the ERIM DB 50/P model and have not been verified on the photographed component. They must therefore not be used as guaranteed ratings or certifications for the product being sold.
🏋️ Mechanical Strength Characteristics
The official ERIM DB 50/P model specifications state:
-
Tensile strength: 850 daN.
-
Bending strength: 450 daN.
-
Compression strength: 6,800 daN.
-
Torsional strength: 6 daN × mm.
These values are provided exclusively as technical reference data for a comparable product. They do not represent certified load ratings for the photographed insulators.
🔧 Additional Tightening and Strength Data
-
Thread: M8.
-
Usable thread depth: 16 mm, according to the measurements provided.
-
Tightening torque: to be verified according to the manufacturer and insert material.
As a reference, ERIM specifies an M8 tightening torque of 22 Nm for its DB 50/P model, with a stated thread depth of 12 mm. Since the photographed component has a stated thread depth of 16 mm and has not been identified as a DB 50/P, the 22 Nm value cannot automatically be considered valid for this product.
🔧 Main Functions
-
Electrical insulation: helps separate live conductors from metal supporting structures.
-
Mechanical support: supports and maintains spacing between copper or aluminium busbars.
-
Fastening: allows connections using M8 female inserts at both ends.
-
Spacing: maintains a defined separation between electrical components and supporting structures.
-
Industrial use: suitable for distribution systems and electrical panels, subject to verification of electrical and mechanical suitability.
- Compact and robust body.
- Suitable for supporting and spacing busbars.
- Can be used in various electrical distribution applications.
📦 Product Condition
Used component, with surface marks and normal signs of handling or previous use, visible in the photographs. It is recommended to check the integrity of the insulating body and the condition of the threads before installation.
