Description

Technical Field

[0001] The utility model relates to the technical field of electric cables and wires, and in particular to a highly flame-retardant insulated cable. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. Cables have many uses, mainly used for control installation, connecting equipment, transmitting electricity and other multiple functions. They are common and indispensable in daily life. They are usually made of one or more mutually insulated conductors and an outer insulating protective layer. They are wires that transmit electricity or information from one place to another. In order to improve the safety of cable use, a highly flame-retardant insulated cable is now used.

[0003] The prior art discloses a flame-retardant low-smoke halogen-free cable with a publication number of CN214312739U. The cable comprises a conductor, an insulating layer, a flame-retardant layer, and a filling cavity, so that when the cable is exposed to flames, the flame-retardant layer made of cross-linked polyethylene and mica tape and the glass fiber in the filling cavity provide the cable with flame-retardant and high-temperature resistant effects, thereby solving the problem that the existing cables have poor flame-retardant effects; the cable comprises a first partition, a second partition, and a support column, thereby forming a hollow structure for the cable, improving the impact resistance of the cable and the protection of the inside of the cable; the support column improves the tensile strength of the cable and plays a role in strengthening the strength of the cable, thereby solving the problem that the existing cables have poor tensile and extrusion deformation effects.

[0004] The above utility model is only provided with one insulating layer and a flame retardant layer. When the flame retardant layer and the insulating layer are damaged, the internal conductor is easy to directly contact with the external fire source or water source, thereby causing a circuit fire or electric shock caused by leakage of electric energy. In addition, the conductors are closely adjacent to each other. When the insulating skin of the conductors rubs against each other and is damaged, it is easy to cause a short circuit between the conductors, so that the insulation and flame retardant effects of the utility model are average, and the practicality is relatively average.
