Cable glands are defined as ‘mechanical cable entry units’ that happen to be employed in conjunction with cable and wiring for electrical, instrumentation & Management, and automation methods, including lights, electricity, info and telecoms.
The principle features with the Cable Gland are to act as a sealing and terminating product to ensure the defense of electrical tools and enclosures, such as the provision of:
Environmental safety – by sealing around the outer cable sheath, excluding dust and humidity through the electrical or instrument enclosure.
Earth continuity – in the case of armoured cables, in the event the cable gland includes a metallic development. In this instance cable glands may be analyzed to make certain they could face up to an suitable peak short circuit fault recent.
Keeping pressure – on the cable to guarantee sufficient amounts of mechanical cable ‘pull out’ resistance.
Added sealing – around the part of the cable getting into the enclosure, whenever a large diploma of ingress security is needed.
Extra environmental sealing – within the cable entry level, protecting the ingress protection ranking of your enclosure with the choice of relevant add-ons elbow cable gland focused on doing this perform.
Cable glands is often built from metallic or non-metallic supplies (or a mix of each) which may even be resistant to corrosion as determined by selection to a typical, or by corrosion resistance checks.
When used in explosive atmospheres particularly, it is critical that cable glands are authorized for the selected form of cable and that they retain the extent of security with the tools to which They can be connected.
