Requirements And Acceptance Of Parallel Groove Clamp Wiring

At present, the installation of return lines in the pipe sections of each operation team is nearing completion. According to the on-site installation experience of the brick well operation team, combined with "Sanhua (98) 1125-09", "Sanhua 1155" and "Sanhua 1159", the connection of the return line to the anchor and the installation of the ground jumper are unified as follows.
1. connector parallel groove connection "1125-09"
All additional lines are connected to the lower anchor. The groove clamp down line used for connection is unified on the Yinchuan side of the pillar, and the up line is connected on the XX side. parallel groove uses JBY-240-3 (LBGLJ185/185), and the center of parallel groove clamp connector is 500mm away from the needle bottle of the return line shoulder. After connection, the wire forms a natural and smooth arc, and the two ends of the wire are exposed 50mm each. When connecting, pay attention to apply electrical compound grease inside pg clamp connector.
2. Grounding jumper installation
Installation at the single arm uses an integral LJ70 conductor from the oblique rod porcelain to the flat rod porcelain, and then tied with the jumper clamp for 50mm, 100mm intervals, and then tied for 50mm, and then coiled into three circles with a diameter of 60mm, and then connected to the return line through the jumper shoulder frame to form a smooth arc. When connecting the jumper and the return line, a torque-equipped reducer pg clampsJBY-240-1 is used. When connecting, the LJ70 line is on the line side of single bolt parallel groove connector. The double arms are tied according to "Sanhua 1159-01-4" and the drawings. The middle is also coiled into three circles with a diameter of 60mm, which is consistent with the drawings. The downlink jumper is in the middle of the arm on the Yinchuan side, and the uplink line is connected in the middle of the arm on the XX side using the JBY-240-1 (LJ70/LJ70) wire clamp and then connected to the return line through the JBY-240-1 (LBGLJ185/LJ70) wire clamp. When connecting, the LJ70 line is on the line side of the wire clamp.
