Description of the Related Art At the factory, the installation position and cutting position of the strain clamp are marked on the wire according to the wire length calculated based on the measured distance between the wire support points (each span length) of each steel tower ) A series of the electric wire which I did is wound in a drum (cut to a standard length of a drum standard) and carried in to a drum field. In the drum field, after measuring the actual length based on the results of precision surveying between the wire support points, cut the wire by this, compress it with a strain clamp at both ends of the cut wire, and compress it with a straight sleeve between the drum-wound wires. (Connecting) work, and after connecting the split wire (pre-fabricated) with a length equivalent to two detenting insulator devices and both the retention clamps of the cut wire, extend a series of wires. In order to do this, it was necessary to perform temporary temporary fixing work (mooring at Kamalong) each time the drawn wire was connected.
The insulator device for supporting the electric wire uses a tension type and a suspension type, a wire type is a drum type, and an overhead wire type is a wheel type (pulling clamp, straight sleeve non-passing), so a protector is used. Interchanging work (temporary suspension of wire extension at the electric wire connection part to move the overhead wire car)
It is carried out. After the wire extension, the electric wire at the end is retained in the insulator of the engine side retracted steel tower, and then temporarily raised by the overhead wire winch in the drum field. Install a wire winch), determine the degree of slack by observing the degree of slack in the wire, hold the wire in the insulator and attach it, remove the split wire, then form and install the jumper wire.
A series of operations such as mounting on the suspension insulator will be performed to complete the entire process of the overhead wire.

業を省略することを特徴とする工法。1. This construction method relates to a construction method of an electric wire (ground wire and electric power line) of a transmission line, and a distance between electric wire support points of each steel tower of the transmission line (horizontal span length measured by precise measurement after completion of the steel tower). And the supporting point height difference), the electric wire is retained from the actual length of the basic electric wire for each span, and the electric wire is cut by the corrected actual length that is obtained by adding or subtracting the correction values such as the shape and size of the insulator device. After pre-stretching), both ends of the cut wire are molded (compressed) by compression type detention clamps, connecting wires that connect the prefabricated wires for each span and the prefabricated wires, and are equivalent to two locking retaining devices. A split wire or split wire with a non-twisted wire of the same length or the same type of wire with connecting fittings (eye processing for wire, extended wire clamp for wire) at both ends is manufactured at the factory, and is A series of Prefabricated electric wires are extended at a large overhead wire winch in the engine field and a tight winch in the drum field, and then tightened together. The insulator device for supporting the prefabricated electric wire uses a tension type and a semi-tensile type or a suspension type, and the wire extension car and the overhead wire car use a flat type and a crawler type through which the tension clamp passes. After the final prefabricated electric wire passes through the drum side (drawer side) detention tower, its terminal detention clamp is retained in the engine side (winding side) insulator of the detention tower, and then a series of large overhead wire winches in the engine field is used. Tension the prefabricated electric wires together, hold the prefabricated electric wires with intermediate diameters on the insulator of each tower one by one, and at the same time, hold the retaining clamp of the prefabricated wire on the insulator of the engine-side retractor. When using the suspension type (straight tower with a small vertical load at the supporting point and a short diameter) on the insulator of the intermediate tower, install a suspension clamp at the mark position of the wire. After completing the installation of a series of prefabricated electric wires in the wire extension section to the insulator device, lower the overhead wire car of each intermediate tower and loosen the split wire (partial wire) on the gold car (in the case of multi-conductor overhead wire, the wire After adjusting each other's slackness using the adjustment metal fittings), remove them, and then attach the prefabricated jumper wires (manufactured at the factory, with compression sockets for connecting to both terminals) to the insulator clamps at the ends of the insulators,
Complete the whole process of installing the electric wire. As described above, prefabricated electric wires, jumper wires, split wires (split wires), etc., manufactured in advance at the factory are sequentially connected at the site, extended, and then bundled together and attached to the insulator device to make each intermediate tower A construction method characterized by omitting the tight-tie work in.
