Abstract
Disclosed is a middling voltage fiber composite cable of a copper strip shielding fiber with temperature measurement and communication functions. The middling voltage fiber composite cable comprises three circular conductor units, with each conductor unit being sequentially coated with a conductor shielding layer, a crosslinking polyethylene insulating layer, an insulating shielding layer, and a copper strip shielding layer from inside to outside. A filling layer covers the surface of the copper strip shielding layer of each of the three circular conductor units. A gap is arranged between the filling layer and the copper strip shielding layer, and a stainless steel pipe is arranged in the gap. The stainless steel pipe is internally provided with a temperature measuring fiber for sensing the cable temperature. A pipe-like communication fiber unit, composed of a loose sleeve, a communication fiber used for data transmission, and a water-preventing fiber paste layer/water-preventing belt layer, is located inside the filling layer. The communication fiber is located inside the loose sleeve while the water-preventing fiber paste layer/ water-preventing belt layer is located between the communication fiber and the loose sleeve. The middling voltage fiber composite cable integrates the pipe-like temperature measuring unit, thereby allowing real-time monitoring of the operating working load of the middling voltage cable and realizing the multi-net integration of the electric power net, the telecommunication network, the broadcasting network, and the internet.
