DEVICE FOR AUTOMATICALLY CALCULATING SAG, CAPABLE OF AUTOMATICALLY AND SIMPLY CALCULATING SAG AND TENSION WHEN INSTALLING A WIRE

摘要

PURPOSE: A device for automatically calculating sag is provided to calculate a sag and tension depending on a region where a wire is installed, thereby easily supplying the sag and tension properly.;CONSTITUTION: A device(1000) for automatically calculating sag comprises a cross arm(200), a suspension cable(300), a dead-end clamp(400), a sag tension measuring device(100), and a wire gripping part(500). The cross arm is joined to an electric pole, thereby being fixed. The suspension cable is connected to the cross arm. The dead-end clamp is connected to the suspension cable. The sag tension measuring device is connected to the dead-end clamp, thereby measuring the tension of a wire. The wire is inserted into the wire gripping part so that the wire gripping part varies the length of the wire.;COPYRIGHT KIPO 2013
