Abstract
The utility model discloses a fire-resistant type electric cable. The fire-resistant type electric cable comprises three conductors, a square tensile core is arranged in the center of each conductor, and a conductor shielding layer, an insulating layer, an insulating shielding layer and a metal shielding layer in sequence wraps outside the three conductors. The three conductors wrapped with the metal shielding layer are arranged in the shape like a Chinese character 'pin' to form a cable core. A drainage wire is arranged in the center of the cable, and a cross section of the drainage wire is in a triangular shape. An outer side of the cable core is wrapped with a wrapping layer, a refractory layer, an armor layer, and a sheath layer. The fire-resistant type electric cable has the advantages of being reasonable in structure, effectively improves shielding performance of the cable due to the fact that the square tensile cores are arranged in the conductors and due to the design of three shielding layers and the drainage wire in the center of the cable, thereby guaranteeing smoothness in electric power connection and communication within a certain period of time, maximally obtaining valuable rescue time, reducing injuries and deaths of people, and ensuring safety of lives and property.
Description
Technical field
