📋 Description
Used product.
DCEI 250 electrical busbar support spacer insulator, identifiable by the marking embossed on the upper part of the component. It is used for the mechanical support, fastening and electrical insulation of conductive busbars inside electrical panels, distribution systems and industrial equipment.
The component features a brown insulating body with a cylindrical structure and a central hexagonal section, designed to facilitate tightening during installation. It is equipped with a female threaded metal insert at one end and a metal connection with a stud and nut at the other.
The structure allows mechanical connections while maintaining the necessary clearance between conductive elements and support structures.
Insulators in this category are generally manufactured from thermosetting composite materials, such as glass-fibre-reinforced polyester resin (BMC/SMC), selected for their insulating properties and mechanical strength. The exact material composition of this particular item has not been verified.
