📋 Description

Used product. The sale lot contains 10 pieces. SM-35 column-type electrical insulator, also known as a barrel-type spacer insulator, designed for the mechanical support and electrical insulation of conductors, busbars and components inside electrical panels.
Made with a rigid red insulating body and M8 threaded metal inserts, it maintains a defined distance between conductive parts and supporting structures, preventing direct electrical contact with frames and metal surfaces.
The external hexagonal geometry facilitates installation and tightening, while the metal inserts provide secure fastening of components.

🏭 Applications

• Power distribution panels: support and insulation of copper or aluminium busbars.

• UPS systems: insulation and fastening of electrical connections and power busbars.

• Battery banks: support for conductors and power connections.

• Photovoltaic and wind power systems: support for busbars and conductors in DC and AC panels.

• Electrical distribution systems: support for busbars and copper strips.

• Industrial automation: insulated fastening of electrical components and conductive plates.

⚙️ Dimensional Specifications

🔧 Main Functions

• Electrical insulation: separation between live conductors and metal supporting structures.

• Mechanical support: support for busbars and electrical components.

• Spacing: maintains the distance between conductive parts and the electrical panel frame.

• Fastening: anchoring using M8 threaded metal inserts.

• Assembly stability: supports busbars and components during normal system operation.

🧱 Materials and Construction Features

• Rigid red insulating body.

• Compact structure with external hexagonal geometry.

• M8 threaded metal inserts.

• Shaped external surface for electrical insulation applications.

• Structure designed for installation inside electrical panels and equipment.

Material note: BMC/SMC resin is commonly used for insulators in this category, but it is not possible to confirm that this is the specific material of this item without a manufacturer's technical datasheet.

⚡ Electrical and Thermal Characteristics

Column-type insulators of this type are used in low-voltage and electrical distribution applications.
However, for the photographed model, there are no sufficient markings or identification documents to confirm:

• Rated insulation voltage of 690/1000 V AC.

• Maximum voltage of 1500 V DC.

• Operating temperature of −40 °C / +130 °C.

• UL94 V-0 self-extinguishing classification.

• Bending and tensile strength.

These values are therefore not attributed to the product as certified specifications.

Technical Note: I have included the applications and general characteristics of SM-35 insulators, but I have not listed the 690/1000 V AC, 1500 V DC, −40/+130 °C temperature range or UL94 V-0 classification as certified specifications, since these are not substantiated by a marking or technical datasheet that can be reliably linked to the photographed item.

📦 Product Condition

Used product, with normal signs of use. The photographs show the red insulating body and metal inserts.
It is recommended to check the condition of the insulating material, ensure there are no cracks and inspect the integrity of the threads before installation.
