Embodiment Construction
[0034] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.
[0035] A self-measuring low-voltage power cable, including a number of insulated wire cores arranged in an outer sheath 6, each insulated wire core is composed of a conductor 1 and a core insulation sheath 2 covering the conductor 1, and a measuring wire is arranged in the outer sheath 6 Wen component 3, such as figure 1 As shown, the temperature measuring assembly 3 includes a temperature measuring wire, and outside the temperature measuring wire is a polyester liner 33, a shielding layer 34 and a plastic wrapping tape 35, and the temperature measuring wire consists of two copper core insulating sleeves 32. The copper core 31 is twisted in pairs, wherein the temperature measuring component 3 is arranged outside the wire core insulating sleeve 2, and is consistent with the length of the wire core insulating sleeve 2.
[0036] Among them, the co...
