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. These red 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.

Frequently Asked Questions
Armour Cable Bushings are designed to protect the internal conductors of armoured electrical cables from sharp metal edges created when the cable armour is cut or stripped. They help prevent insulation damage, reducing the risk of short circuits and improving electrical safety.
Armour Cable Bushings, also known as BX Cable Bushings or Anti-Short Bushings, are safety components installed between the cut metal armour and the insulated conductors inside BX, FMC and other metal-clad cables to provide a protective insulating barrier.
Armour Cable Bushings fit inside the end of an armoured cable where the metal armour has been cut. They create a smooth protective barrier that prevents sharp metal edges from contacting and damaging the insulation around the internal conductors.
Yes. Armour Cable Bushings are suitable for both indoor and outdoor installations and are capable of operating in temperatures as low as -40°C, making them suitable for harsh industrial and environmental conditions.
