Precautions For Selecting Tension Clamps

It should be noted that the outer diameter of the LGJ conductor is calculated by adding the aluminum wire cross section of 185mm and the steel core cross section of 30mm, not simply by the aluminum wire cross section of 185mm. LGJ conductors of the same specification have different steel core cross sections and conductor outer diameters, so the bolted type strain clamp used by 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. In addition, since dead end strain clamp is clamped on the outer diameter of the conductor, we require the outer layer of the LGJ or LJ conductor to be wrapped with aluminum tape during construction to prevent damage to the conductor when bolted dead end clamp is crimped.
