Removal of moisture inside the cable When the cable or cable near the joint is damp less than 3m, the lead sleeve can be longitudinally dissected. After the moisture is removed by the above method, the lead sleeve can be longitudinally sectioned or wrapped with a lead sleeve larger than the outer diameter of the cable lead sleeve before sealing and welding. If the damp core wire exceeds 3m. Then connect this section of cable.
Change cable Prepare a new cable longer than the cable to be removed for change. Before the connection is changed, the new and old cable cores must be numbered and paired one by one to avoid wrong connection and audio calls. When the connection is changed, the two connection points should be paired once, paired and paired, I .e. the two parties should pair the new cable first, and then pair the old cable (using cable) with the same number. When the user does not talk, the two parties will cut off the old line pair and connect the new cable pair that has been connected. Other core wires shall be connected in this order. Generally, after every 5-15 pairs are changed, the measuring room shall be notified for testing. If it is confirmed that the changed connection is correct, the changed connection can be continued until the changed connection is completed. The welding joint will be sealed after modification.
