Fire-resistant multi-core flexible cable for communication power supply

The invention relates to a fire-resistant multi-core flexible cable for a communication power supply, which comprises an insulation wire core (1), and is characterized in that a mica tape (2) is arranged outside the insulation wire core (1); a cabling filling rope (3) is arranged outside the mica tape (2); a cabling warping tape (4) is arranged outside the cabling filling rope (3); a zero-halogen low-smoke polyolefin sheath (5) is arranged outside the cabling warping tape (4); the cabling filling rope (3) is a flame-resistance inorganic paper rope; and the cabling warping tape (4) is zero-halogen low-smoke high-flame resistance fire insulation glass cloth wrapping tape. In the fire-resistant multi-core flexible cable for the communication power supply, the inorganic paper rope as the filling rope and the zero-halogen low-smoke high-flame resistance fire insulation glass cloth wrapping tape are adopted to replace a glass fiber rope and a glass fiber tape used in an original product. All performance indexes of the fire-resistant multi-core flexible cable for the communication power supply completely meet and are superior to the requirement of a YD/T1173-2001.
