Cable Glands are mechanical cable entry and protection devices, which can be manufactured from metallic or non-metallic materials. These are used in conjunction with cable and wiring in the electrical, automation and instrumentation systems of most industries. Cable glands may be used with all types of electrical-power, instrumentation, telecommunications and control cables.

MAIN FUNCTIONS OF THE CABLE GLANDS:

• Provide external protection by sealing the outer cable sheath, preventing dust and moisture from entering the electrical or instrument enclosure.
• May provide additional sealing on the part of the cable entering the enclosure when a high degree of ingress protection is required.
• May provide additional environmental sealing at the cable entry point, maintaining the ingress protection rating of the enclosure with the selection of applicable accessories dedicated to performing this function.
• May facilitate earth continuity in the case of armoured cables, when the cable gland has a metallic construction.
• May provide a holding force on the cable to ensure adequate levels of cable pull out resistance.
• When used in explosive atmospheres, these are required to maintain the level of protection of the equipment to which they are attached.
