During on-site installation, many people mistakenly believe that the critical step for a shear bolt connector is simply “snapping off the bolt.”
However, in actual cable trench environments, the real issue is not merely whether the bolt breaks, but the conditions under which it breaks.
As seen in the site photos, the cable has been laid and its ends are ready for processing, with tools and accessories already in the work area. Space is limited at this stage; factors such as the cable bending radius, conductor positioning, the orientation of the shear bolt connector, and the installer’s working angle all influence the final installation outcome.
Therefore, one must consult the product installation manual before starting, rather than relying solely on experience to tighten the bolts.
First, verify that the conductor is inserted to the specified position. Simply entering the shear bolt connector does not mean the conductor has reached the proper depth. Insufficient insertion depth can shift the point of force application during tightening, potentially causing localized deformation of the conductor due to concentrated pressure.
Second, follow the tightening sequence specified in the manual. For multi-bolt designs, the order of tightening matters. A correct sequence allows the clamping force to build up gradually, preventing excessive stress at a single point that could compromise the contact between the conductor and the inner wall of the connector body.
Failure to follow the manual can lead to issues such as localized conductor deformation, abnormal stress angles on the bolts, and uneven thread loading. In severe cases, bolt threads may strip, necessitating on-site rework or connector replacement, and potentially interfering with the subsequent installation of heat-shrink or cold-shrink accessories.
True professional installation focuses not on “quickly snapping off the bolt,” but on ensuring every step complies with the product manual.
Only in this way can the SUNJ shear bolt connector deliver stable, consistent, and repeatable connection results.
