Armour Cable Bushings
High-impact red polyethylene armoured cable bushings designed for BX cables, FMC cables and metal-clad electrical installations. UL and CSA certified anti-short bushings protect internal conductors from sharp metal edges, preventing short circuits and ensuring electrical safety compliance. Available in multiple sizes with internal diameters from 9.4mm to 18.5mm, suitable for temperatures as low as -40°C.
What Are Armour Cable Bushings?
Armour cable bushings, also known as BX cable bushings or anti-short bushings, are essential safety components designed to protect electrical conductors inside armoured cables from damage caused by sharp metal edges. These specialised bushings fit between the cut metal armour and the internal wires of BX cables, FMC (Flexible Metal Conduit) cables, and other metal-clad cable types.
Manufactured from high dielectric polyethylene, armoured cable bushings create a protective barrier that prevents the sharp edges of cut or stripped cable armour from penetrating the insulation of internal conductors. This crucial protection reduces the risk of short circuits, electrical shocks, and fire hazards that can occur when metal edges compromise cable insulation.
Our armour cable bushings are certified electrical safety products registered under Underwriter's Laboratories File E51579 and Canadian Standards Association File 213252, ensuring they meet rigorous international safety standards for electrical installations. The high-impact red colour provides clear visual identification during installation and inspection, making it easy for electricians to verify proper armoured cable termination.
These bushings are designed to withstand extreme operating conditions, functioning reliably in temperatures as low as -40 degrees Celsius. This makes them suitable for both indoor and outdoor electrical installations, including harsh industrial environments where temperature extremes are common.
