How are bolts through insulating bushings to be inserted?

The proper method for inserting bolts through insulating bushings is hand insertion. This ensures a careful and controlled application of force, which is critical for maintaining the integrity of insulating materials. Hand insertion allows the operator to monitor the alignment and the tightness of the connection, preventing potential damage to the insulating bushing or the bolt threads. This method also minimizes the risk of applying excessive torque, which could compromise the insulating properties of the bushing.

Control over the insertion process is essential in applications where electrical insulation is crucial, as improper insertion could lead to electrical failures or shorts due to damaged insulators. Using automated methods or machinery may not afford the same level of precision and oversight necessary for these critical components. Thus, hand insertion is favored in situations where safety and reliability are paramount.
