Interpower Strain Reliefs/Cable Glands

A strain relief or cable gland secures the cable of a power cord to the panel of the electrical equipment. It provides protection to the wires and cables from stress and damage as it runs through the panel of the equipment. It does not relieve strain on a cable as it exits the equipment, but it relieves the strain on the electrical connection and circuitry inside the equipment. The term “strain relief” is commonly used in North America, while “cable gland” is commonly used throughout Europe and the other parts of the world.

North American and international strain reliefs from Interpower can provide a liquid-tight seal on the power cord entry and, at the same time, provide extra protection to power cords. Strain reliefs extend cord life and reinforce the cord connection to equipment. These strain reliefs are intended for use in mechanically securing a power supply cord to a piece of equipment in accordance with various international equipment standards.

Strain Reliefs/Cable Glands Available at Interpower

There are many different sizes for each type of strain relief/cable gland. To see what is available, see Strain Reliefs on the Interpower website or click on the link below each photo for specific dimensions.

Using a Conduit

Interpower also offers conduit for use with nipples or elbows. This highly flexible corrugated conduit is made of Nylon 6/6 and is flame-retardant and self-extinguishing. It features excellent crush resistance, resistance to heat, UV exposure, and certain chemicals. Wires or cable are threaded through conduit in situations where the wire and cable need extra protection (from elements or physical damage) or where users may need to add additional wires at a later time.

The push-in conduit system connects flexible nylon conduit to either a straight or 90° push-in fitting. The polyamide nipples feature a ridge that snaps into the grooves of the corrugated conduit to hold the conduit in place. The conduit can be mounted and can be rotated for non-liquid applications by pushing the conduit into the fitting until it stops. For rigid, liquid-tight applications, the conduit should be pushed farther into the fitting until it clicks again. These fittings are available in the nipple version or the 90° angled elbow version strain relief.

85826500 (Nipple) 85826700 (Elbow)
