Fiber composite high voltage power cable

The invention provides a fiber composite high voltage power cable which comprises a conductor unit and a sheath unit. A buffer water blocking layer is provided outside the conductor unit. The buffer water blocking layer is provided with a fiber unit and two soft wires inside. The fiber unit and the two soft wires are parallel with a distance. Compared with a traditional fiber temperature measurement system, the invention provides the fiber composite high voltage power cable of which the fiber unit is directly embedded into a cable structure. The fiber composite high voltage power cable has the following advantages that: 1. manufacture of a temperature measurement optical cable protection layer is saved, a stainless steel sleeve pipe is directly employed, a metal sheath and an oversheath of the cable are taken as a protection layer, and manufacture cost of a temperature measurement optical cable is reduced; 2. all cost of temperature measurement optical cable laying and installation are saved, and cost of a high voltage power transmission system is reduced. A corrugated aluminum sheath employed in the invention has a certain cushioning effect on extraneous impact, and destruction of a fiber structure by the extraneous impact can be substantially reduced.
