Embodiment

[0009] There are 98 buildings in a village in Xiangtan County, Hunan Province, each with 3 wires (live wire, neutral wire, ground wire) 16mm 2 Steel-cored aluminum stranded overhead wire power supply, two 10mm incoming wires 2 (live wire, neutral wire), one 4mm 2 (Ground wire) Copper-plastic wire. Joint processing steps: cut about 300mm long steel-cored aluminum stranded wire (remove the steel core) and connect it with the incoming copper-plastic wire → put the connected steel-cored aluminum stranded wire and the incoming copper-plastic wire into the prepared in advance The bamboo tube (its inner diameter is 6mm larger than the outer diameter of the steel-reinforced aluminum stranded wire, and the length is 100mm) → seal the end of the bamboo tube near the copper wire with dry mud → pour the tin liquid into the bamboo tube → turn the bamboo tube upside down, put Remove the mud that blocked the end of the bamboo tube, and pour tin liquid into the bamboo tube → cut open the ba...

Abstract

The invention relates to a connection processing method of ASCR and copper wire, belongs to the technical field of power supply line installation and solves the problem that when outdoor ACSR and the copper wire are connected, a white powder material can be generated to result in bad contact between the ACSR and the copper wire and to accordingly cause frequent outage and fire hazards. The technical emphasis of the connection processing method of the ASCR and the copper wire is to prevent rainwater or moist air from entering the contact surfaces of the ASCR and the copper wire. The connection processing method comprises the steps of firstly, cutting a piece of ASCR with steel core removed to connect with a house lead-in copper wire; secondly, enabling the two connected wires to penetrate a bamboo tube; thirdly, plugging the opening of the bamboo tube, which is close to the copper wire end; fourthly, filling molten tin into the bamboo tube; fifthly, reversing the bamboo tube after the molten tin is solidified and subjecting the other end of the bamboo tube to tin supplement; sixthly, removing the bamboo tube and sleeving the tin cylinder with a plastic tube; and lastly, connecting the ACSR at one end of the tin cylinder with the ACSR on an outdoor pole. According to the connection processing method of the ASCR and the copper wire, the joint of the ASCR and the copper wire can maintain good contact, cannot generate the white powder material and accordingly affect normal power supply and can eliminate the fire hazards. An attached figure is provided.

Description

technical field [0001] The invention relates to the technical field of power supply line installation and processing. Background technique [0002] At present, the overhead wires in rural areas of our country basically use steel-cored aluminum stranded wires, and most of the incoming wires of every household use copper-plastic wires. The connection between the steel-cored aluminum stranded wire and the copper-plastic wire will produce a white powdery substance called aluminum oxide, which often destroys the connection of the copper-aluminum wire, causing the joint to fire and the line power supply to be interrupted. The usual way to deal with this problem in rural areas is to repeatedly tap the joint of copper and aluminum wires with a long bamboo pole, hoping that the white powdery substance will fall off and the power supply will be normal, but the effect is very poor and it is not safe. The traditional way to deal with copper-aluminum wire connection is to use a special ...
