Cable Strain Relief

Strain relief devices protect electrical equipment by absorbing the push and pull forces exerted on the attached wires and cables. They provide the cables with protection against over-bending, fraying and cutting and, they keep the cables in a stationary position to prevent twisting and pulling. 

Strain reliefs are available in either a dome or flex body style. A dome-style strain relief provides protection for the cable against the possibility of cutting, due to sharp edges of the attached devices or electrical panel. Flex-style strain reliefs offer flexible bend protection from stress that is applied perpendicular to the axis of its entry into the equipment. It also helps to prevent kinking as the cable is pulled at extreme angles.

Cable size is very important when specifying a strain relief. The outer diameter of the cable must be known in order to select the appropriate strain relief. A strain relief’s diameter refers to the diameter of the cable designed to pass through. The mounting size refers to the size of the strain relief’s threads, which are used to connect the strain relief to a device or panel.
