Abstract

The invention relates to the technical field of cables, and relates to a fireproof flame-retardant and moistureproof cable which comprises a flame-retardant PVC sleeve, an aluminum tape layer, an anti-theft layer, a braided layer, a mica tape high-temperature-resistant layer, a surrounding pipe, an outer sheath, an inner lining layer, a ceramic silica gel wrapping tape and a cable core layer. Thealuminum strip layer is welded to the inner side of the flame-retardant PVC sleeve, and the anti-theft layer is arranged at the inner side of the aluminum strip layer. The cable is reasonable and compact in structure and is convenient to use. With the arrangement of an oxygen isolation cavity, the flame-retardant effect of the cable is improved. The cable is covered by a flame blocking strip whenbeing burnt out, so that the spread of fire is prevented further, and the fireproof effect of the cable is improved. The moisture infiltrated from the outside is isolated through the flame-retardant PVC sleeve, the waterproof isolation sleeve and a damp-proof film, after the moisture infiltrates into the surrounding pipe, the moisture is discharged to the outer side of the cable through the waterdiversion pipe, the interior of the cable is protected against damage through a tinned steel wire outer layer, a steel belt wrapping middle layer and a high-carbon galvanized steel wire inner layer inthe anti-theft layer, and the anti-theft performance is enhanced.

Description

Technical field [0001] The invention relates to the technical field of cables, and is a fire-resistant, flame-retardant and moisture-proof cable. Background technique [0002] With the rapid economic development, China’s power industry has also developed rapidly, which has promoted the development of the cable industry. Cables are wire products that transmit electrical energy, electrical signals, and realize the conversion of electromagnetic energy. Cables usually consist of a cable core that transmits electrical power or electrical signals. It is composed of a protective and insulating sheath. The cable core in the cable is made of a metal material with good electrical conductivity, usually copper (good electrical conductivity) or aluminum (lower cost), but the cable in the prior art , It does not have a certain fire resistance and flame retardancy, and it is easy to cause damage to the cable in unexpected situations. In addition, the cable does not have a certain waterproof eff...
