Selection Of Line Tension Clamps When Using Lgj And Lj Conductors

When using LGJ or LJ conductors, since the suspension clamp for abc cable is clamped on the outer diameter of the conductor when used, the suspension clamp for lt ab cable model to be used should be selected according to the outer diameter of the conductor. For example, when using LGJ-185/30 conductor in power lines, it is calculated that its
outer diameter is 18.88mm. From the above table, it is known that the suspension clamp should be NLL-4, NLL-5 or NLD-4.
It should be noted that the outer diameter of the LGJ conductor is calculated by adding the aluminum wire cross section 185mm and the steel core cross section 30mm, and the conductor
outer diameter is not simply calculated by the aluminum wire cross section 185mm. LGJ conductors of the same specification have different steel core cross sections and conductor
outer diameters, so the fiber suspension clamp used by LGJ conductors of the same specification are not necessarily the same. If it is an LJ conductor, since it does not have a
steel core, the cross section of the aluminum stranded wire can be used to calculate the conductor
outer diameter.
In addition, since the cable suspension clamp is clamped on the outer diameter of the wire, we require that the outer layer of the LGJ or LJ wire be wrapped with aluminum tape during construction to prevent damage to the wire during crimping.
