These clamps operate through a wedge mechanism that, when bolts are tightened, forces the clamp’s arms to close around the cable, providing a secure grip.
NEJ Wedge Strain Clamps are suitable for a variety of insulated cable sizes, particularly those used in low-voltage power distribution systems.
Factors to consider include the size and type of the cable, the operating voltage of the system, and the installation environment to ensure the correct model is chosen.
