Abstract
The utility model discloses a flexible fireproof power cable for rated voltage 0.6/1KV. The flexible fireproof power cable comprises a conductor which is successively coated with an insulating layer and an extrusion layer. The extrusion layer is covered with an oversheath which is a thread-shaped copper pipe. The insulating layer is formed by wrapping of a multilayered mica tapes. According to the cable provided by the utility model, 0.8-2.0mm of the insulating layer formed by wrapping of the mica tapes is adopted to cover the conductor, and then ceramic silicone rubber is used as the extrusion layer to cover the conductor. The mica tapes and the ceramic silicone rubber are used for fireproof protection of the conductor, and fire-resistant temperature can reach 950-1000 DEG C. The oversheath of the cable is a spiral cylinder. Fireproof, waterproof and acid-alkali resistant effects are achieved, and flexibility of the oversheath is also enhanced. Thus, flexibility of the whole cable is enhanced. Polypropylene ropes are adopted to fill gaps between multi-core conductors so as to raise tensile strength of the cable. Meanwhile, a shielding effect is also achieved.
