Embodiment Construction
[0026] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0027] like figure 1 The copper wire shielded medium-voltage optical fiber composite cable shown in the smart grid includes a cable core and an outer sheath 9 covering the outside of the cable core. Wherein: the cable core includes a conductor 1, a conductor shielding layer 2, an insulating layer 3, an insulating shielding layer 4, and a semiconductor buffer layer tape 5 that are sequentially coated on the outside of the conductor 1, and copper wires 6 are evenly wound around the semiconductor buffer layer tape 5. and the metal temperature measuring optical unit 7 , the copper wire 6 and the metal temperature measuring optical unit 7 are covered with a copper strip 8 .
[0028] like figure 2 As shown: the metal temperature measuring optical unit 7 includes a temperature measuring optical fiber 70, a fiber paste 71, and a stainless steel tube 72 coat...
