Stability Check Of Parallel Groove Clamps

On-site personnel should start by checking the surface cleanliness and the condition of fasteners, visually observing the cleanliness of the contact surface between parallel groove clamp connector and the wire, as well as the tightness of the bolts and nuts. If there are oxides, oil stains or other contaminants on the surface of the conductor, it may affect the contact effect between pg clamp connector and the conductor, thereby affecting the mechanical compatibility of the connection. Deformation of the bolts and nuts may also indicate potential loosening or uneven stress.

Use a torque wrench to check the torque of the pg clamps fastener. Apply the specified torque value to all fasteners according to the technical parameters provided by the single bolt parallel groove connector manufacturer. This process can reflect whether the force is applied evenly during installation and whether there is a risk of loosening. Uniform torque distribution is crucial for the parallel groove clamp timer to maintain a reliable contact configuration under load.

In the field, electrical testing equipment may also be used to measure the resistance or continuity of the parallel groove connector connection. A low and stable resistance value indicates that the current path between the wire and the aluminium pg clamp is as expected; a reading that deviates significantly from the recommended range suggests that there may be poor contact or installation misalignment at the contact surface.
