Beschreibung
Zusammenfassung:	The water supply pipeline comprises more than two pipeline units, each pipeline unit comprises a core pipe and an electric insulation medium coating layer located outside the core pipe, a metal wire is arranged between the core pipe and the electric insulation medium coating layer, the metal wire is arranged in the axis direction of the core pipe, and the metal wire is connected with the electric insulation medium coating layer. The metal wire is connected with a resistance detection device for measuring the resistance of the metal wire, the two ends of the core pipe and the two ends of the metal wire are located outside the electric insulation medium coating layer to form a connecting part, the core pipes corresponding to the adjacent pipeline units are in hot melting or electric melting connection, and the detection wires are in contact connection; the outer side of the connecting part is sleeved with a shrinkage protective sleeve, and the two ends of the shrinkage protective sleeve are arranged on the two
