The invention provides an energy-saving halogen-free cable for fire protection of an intelligent building, and relates to the fields of electric control and fire-proof technology. A wire core of the energy-saving halogen-free cable consists of a high-quality anaerobic copper conductor strand, a double-layer fire-resistant mica tape wrapping and a high-temperature-resistant fluoroplastic insulating layer; a cable formation wrapping tape is externally provided with double layers of copper belts or copper wires for weaving and shielding; a high-flame-retardant glass fiber belt is arranged outside a shielding layer; and a flame-retardant low-smoke halogen-free polyolefin jacket is arranged outside the high-flame-retardant glass fiber belt. The energy-saving halogen-free cable has better flame-retardant property and fire-resistant oxygen isolation physical performance, and can guarantee the electric energy to be normally transmitted even if fire is caused, thus providing powerful safeguard for safe escape and timely rescue.
Description
technical field [0001] The invention relates to the technical fields of power control and fire resistance. Background technique [0002] Cables are extremely important for the normal transmission of electrical energy in the event of a fire, and to gain valuable time for safe escape and timely rescue. Due to the occasions used, the application of new building materials, and long working hours, they are often Performance and flame retardant performance can not meet the design requirements and a fire occurs, causing heavy losses to the life and property of the country and the people. Contents of the invention [0003] The purpose of the present invention is to design a fire-resistant flame-retardant halogen-free cable with high flame resistance, oxygen insulation and fire resistance, which can normally transmit electric energy in case of fire, and win valuable time for safe escape and timely rescue. [0004] The technical solution of the present invention is: the present inv...
