Abstract

The invention relates to an improved high-performance flame-retardant cable which sequentially comprises a circular structure conductor, a conductor shielding layer, a fluoroplastic insulating layer and an insulating shielding layer. A filler is arranged in a gap of a cable core, and a wrapping layer, a flame-retardant layer I, a braided layer, a flame-retardant layer II and an outer sheath are sequentially arranged outside the cable core and the filler. Four humidity-sensitive insulated wire cores are embedded in the braided layer, the two sides of each humidity-sensitive insulated wire core are respectively provided with the water-blocking ropes, and the flame-retardant layer I and the flame-retardant layer II comprise the following steps of (1) mixing raw materials step by step; (2) putting the mixture into a banburying furnace for banburying; and (3) melting a copolymer, and carrying out injection molding. The cable is excellent in transmission performance, and larger current is introduced by the humidity-sensitive insulating wire cores to dissipate heat, so that moisture is taken away, the overall flame-retardant effect is good, the service life is long, and the flame-retardant layer is excellent in flame-retardant performance and is convenient to process.

Description

technical field [0001] The invention relates to a flame-retardant cable, in particular to a preparation method of a flame-retardant cable and a flame-retardant layer. Background technique [0002] With the rapid development of the national economy, as the main artery of the national economy, the amount and scope of wire and cable are increasing. In recent years, power plants, substations, smelting and petrochemical industries have a great demand for cables. [0003] Existing flame retardant cables have the following deficiencies: ① conductor transmission performance is average; ② used in a humid environment, there is no good solution to the moisture that has entered; ③ there is room for improvement in flame retardant performance. Contents of the invention [0004] Purpose of the invention: The purpose of the present invention is to overcome the deficiencies in the prior art and provide an improved high-performance flame-retardant cable with excellent transmission performa...
