📋 Description
Used product. Lot consisting of 10 hexagonal electrical support and spacer insulators, designed to support and secure busbars inside electrical panels, transformer substations and industrial equipment.
The components feature 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. These components are used to support and maintain spacing between conductive parts, helping to electrically insulate them from their supporting structures.
🏭 Applications
- Industrial and power distribution electrical panels.
- Support and spacing of copper and aluminium busbars.
- Electrical substations and transformers.
- Power centres and distribution equipment.
- Low-voltage industrial electrical systems.

🧱 Materials and Construction Features
The material cannot be identified with certainty from the photograph alone. For this type of busbar support insulator, the manufacturer ERIM documents the use of:
-
BMC RF 3/20 polyester compound, reinforced with glass fibres.
-
Metal inserts made of zinc-plated steel.
- Thermosetting structure.
These characteristics are documented for the ERIM DB 40/P model, which is dimensionally comparable, but are not attributed as confirmed specifications of the components being sold.
⚡ Voltage and Insulation Values
As a technical reference, manufacturer ERIM specifies the following values for its DB 40/P model:
-
Operating voltage: 1000 V.
-
AC surface flashover voltage: 10 kV.
-
AC internal flashover voltage: 40 kV.
-
Operating temperature: from -40 °C to +130 °C.
-
Fire behaviour: UL94-V0.
-
Railway classification: HL2 according to EN 45545-2.
These values have not been verified on the photographed items and must not be considered certifications or guaranteed performance ratings for this lot.
🏋️ Mechanical Strength Characteristics
The official ERIM DB 40/P model specifications state:
-
Tensile strength: 1,100 daN.
-
Bending strength: 800 daN.
-
Compression strength: 8,300 daN.
-
Torsional strength: 10 daN × mm.
These figures are provided exclusively as technical reference values for the comparable model. They are not verified load ratings for the insulators in this lot.
🔧 Additional Tightening and Strength Data
For the ERIM DB 40/P model, the official documentation specifies:
-
M8 thread: 13 mm depth.
-
M8 tightening torque: 20 Nm.
The lot being sold has a stated usable thread depth of 14 mm. The 20 Nm torque is therefore provided only as a reference for the comparable model and not as a certified value for these components. The actual manufacturer's instructions must be checked before installation.
🔧 Main Functions
-
Electrical insulation: helps separate live conductors from metal supporting structures.
-
Mechanical support: supports and maintains spacing between busbars.
-
Fastening: allows connection using M8 female inserts at both ends.
-
Spacing: maintains a defined separation between electrical components and supports.
-
Industrial applications: suitable for use in distribution systems and electrical panels, subject to verification of electrical and mechanical suitability.
- Compact and robust construction.
- Ideal for electrical support and spacing applications.
📦 Product Condition
Used components, 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.
