Our bolt connection terminals for low voltage have a modular structure and consist of an insulation body (insulator), the corresponding lead-through bolt and the associated fastening and insulation materials (cardboard washers, nuts, etc.).
The bolts are made of brass or copper, the insulators are made of ceramic.
Ceramic insulators are used wherever materials with high dielectric strength and temperature resistance are required.
They also have particularly good mechanical stability and are extremely tough and abrasion-resistant, which is extremely important in harsh environmental conditions.
