Description

A bushing conductor stud is a component with which the electrical connection between an enclosure in type of protection “Flameproof enclosure d“ and its connection enclosure in type of protection “Increased Safety e“ is established. The cable bushing includes a threaded metal sleeve, a ceramic insulation, terminals and a stud. Standard threaded sleeves from M16 to M42 are included in the delivery of bushing conductor studs.

The diameter of the stud depends on current and the terminal size on the cable diameter. Thanks to different types of terminals, vertical as well as horizontal cable connection is possible. Special terminals are available on request. After installation, the bushing conductor stud needs to be secured by means of a nut or adhesive to prevent self-loosening.
