Inspection methods during the production of terminal wires?

Terminal lines provide services for groups of load sources, such as trunk lines, switching devices, control systems, etc. Load source is the service object of the terminal line, usually refers to the user equipment; broadly speaking, the upper level of equipment is the next level of equipment load source. In telephone communications, the load source is also known as the source, the number of service equipment contained in the terminal line, known as the terminal line capacity.

1) terminal line burned out fault detection and judgment in the circuit of the power system, which point of the iron, the electric terminal line burned to where, its burned out and intact parts of the intersection, can be considered that the wire iron; if the electric terminal line burned out to the wiring parts of an electrical device, it is indicated that the failure of the electrical equipment. 2) between the line of the short-circuit, disconnection, poor contact detection and judgment of the failure of the terminal line is subjected to external extrusion, Impact, caused by the electric terminal line wire insulation layer damage, resulting in a short circuit between the wires. Judgment, you can remove the electrical equipment and control switches at both ends of the electric terminal line plug connector, with a meter or test lamp to detect the short circuit of the line. Wire break fault, in addition to the obvious break phenomenon, the common fault occurs between the wire and wire terminals. Some wires after the break, the outer insulation layer and wire terminals intact, but the wire within the core wire and wire terminals have been disconnected. Judgment, suspected of breaking the conductive line and wire terminals to do the tension test, in the tension test process, such as wire insulation layer gradually thin, can confirm that the wire has been broken. Poor line contact, the fault occurs in the plug. When the fault occurs, it will cause the electrical equipment can not work properly. Judgment, turn on the power of the electrical equipment, touch or pull the electrical equipment of the relevant plug, when touching a plug, the work of the electrical equipment is suddenly normal, suddenly not normal, indicating that the plug has a fault.
