Cable glands are used to secure the ends of an electrical cable to the equipment. Cable glands provide strain-relief and connect by a means suitable for the type and description of cable for which it is designed--including provision for making electrical connection to the armour or braid, if any. Cable glands may also be used for sealing cables passing through bulkheads, gland plates or other security devices.
Cable glands are engineered for installation and removal, providing strain relief in cable runs. The cable glanding of a hardline installation can be done either before or after the sheathing is applied. Cable glands provide strain relief to prevent damage to the wire sheath or annulus, helping to extend cable life by preventing bending and twisting forces that usually occur during installation or removal.
Cable glands are designed to connect the end of an electrical cable to the equipment. Cable glands will support the weight and tension of a thick cable, withstanding pressure including accidental damage and extreme temperatures up to 120 degrees Fahrenheit. They are used in many applications including: telecommunications, computer networks and powerlines.
Conduit glands are used to prevent the cable from rubbing on surfaces, though they can be used for other purposes such as sealing cables through bulkheads or gland plates.
