Precautions for selecting bolt-type tension clamps

It should be noted that the outer diameter of the LGJ conductor is calculated by adding the cross section of the bolted type strain clamp aluminum wire 185mm and the cross section of the steel core 30mm, not simply by the cross section of the dead end strain clamp aluminum wire 185mm. LGJ conductors of the same specification have different steel core cross sections and conductor outer diameters, so the bolted dead end clamp used in LGJ conductors of the same specification is not necessarily the same. For LJ conductors, since they do not have a steel core, the cross section of the aluminum stranded wire can be used to calculate the outer diameter of the conductor.
