ABSTRACT:
The present invention discloses a wire stranding roller and a new method for the same, in a LP insulator being mounted at a cross arm of pin long column and insulating and supporting a high voltage wire, which drastically improves workability and greatly reduces construction cost because the location of a wire don't need to be changed after the stranding and wire pulling, which is easy to work with and is very effective in reducing labor cost and preventing a safety accident because it can easily perform wiring and removing works no matter how large the weight of the wires would be, which is capable of precisely adjusting a dip (degree in which the wire hangs down) because the wire are placed on an insulator, which is to be mounted, during a wire pulling work and also which can solve the problem of securing a work space when carrying out the work applying and uninterruptible method by forming a open-and-shut roller capable of wire insertion and a wire stranding roller consisting of an insulator coupling opening and directly coupling them on the upper surface of the LP insulator.
