Cable glands are used on all types of electrical power, control, instrumentation, data, and telecommunications cables. They are used as a sealing and termination device to ensure that the characteristics of the enclosure that the cable enters can be maintained adequately.
A double compression cable gland is typically made for all unarmored and armored cables. Its function is to offer compression for both on the inner sheath and cable armored. It also offers electrical continuity and strain relief for the electrical cables within.
