What is a cable gland? An Introduction

Cable glands are described as ‘mechanical cable entry products’ that happen to be made use of at the side of cable and wiring for electrical, instrumentation & Manage, and automation programs, which includes lights, ability, info and telecoms.

The principle functions with the Cable Gland are to work as a sealing and terminating unit to ensure the security of electrical devices and enclosures, such as the provision of:

Environmental security – by sealing to the outer cable sheath, excluding dust and dampness from the electrical or instrument enclosure.

Earth continuity – in the case of armoured cables, in the event the cable gland contains a metallic construction. In this case cable glands could possibly be examined making sure that they will endure an ideal peak quick circuit fault existing.

Holding power – over the cable to be certain sufficient amounts of mechanical cable ‘pull out’ resistance.

Supplemental sealing – over the Element of the cable getting into the enclosure, whenever a significant degree of ingress security is necessary.

Supplemental environmental sealing – with the cable entry stage, preserving the ingress safety rating of your enclosure with the choice of relevant elbow cable gland extras committed to accomplishing this function.

Cable glands could be constructed from metallic or non-metallic products (or a mix of equally) which can also be proof against corrosion as determined by choice to a normal, or by corrosion resistance tests.

When Utilized in explosive atmospheres specifically, it really is vital that cable glands are accredited for the chosen style of cable and which they retain the level of defense of your devices to which These are connected.
