Parallel Groove Clamp Installation: Strictly Follow The Torque Values ​​in The Instruction Manual And Stop Applying Force Immediately.

During power laying and splicing, when using parallel groove for parallel conductor splicing, each conductor should be accurately placed in the cable tray, and the bolts should be tightened according to the torque values ​​specified in the instruction manual. Once the final torque value specified in the manual is reached, tightening should be stopped immediately.

This practice is based on scientific calculations of the parallel groove clamp connector design parameters. By considering the maximum allowable temperature rise, the conductor's operating current, and the maximum radial pressure it can withstand, the minimum and maximum pressure ranges corresponding to pg clamp connector can be calculated, thus determining the bolt tightening torque range.

If this range is exceeded during installation, overtightening the bolts may damage the conductors, affecting long-term operational stability. Conversely, insufficient torque may lead to poor contact between the conductor and the fittings, causing abnormal contact resistance and the risk of temperature rise.
