Helping to Protect the Electrical Connection with a Strain Relief/Cable Gland

Posted on 11/19/18 3:26 PM

Strain reliefs, also known as cable glands, can have an important role in the design of equipment which uses power cords. The main purpose of a strain relief/cable gland is to help protect the electrical connection and circuitry inside the equipment. It helps to eliminate tugs or pulls on the power cord that could cause the wires to become disconnected resulting in injury, accident, or failure of equipment.
