Embodiment Construction

[0025] As shown in the figure: a medium and high voltage mineral flame-retardant and fire-resistant cable, which is composed of several cable cores, fillers 6 and flame-retardant outer sheaths. The cable cores are placed inside the flame-retardant outer sheath, and each cable core From the inside to the outside, it is composed of conductor 1, conductor shielding layer 2, insulating layer 3, insulating shielding layer 4 and metal shielding layer 5. The conductor shielding layer 2 is evenly covered on the surface of the conductor 1, and the insulating layer 3 is covered on the conductor shielding layer. 2, the insulation shielding layer 4 is evenly covered on the surface of the insulation layer 3, the metal shielding layer 5 is made of soft copper tape that is overlapped and wrapped, the conductor shielding layer 2 and the insulation shielding layer 4 are both cross-linked semi-conductive layers, and the filler 6 The non-moisture-absorbing easy-to-tear polypropylene filler is use...

Abstract

The invention relates to a medium-high-voltage mineral flame-retardant fireproof cable and a production method thereof. The medium-high-voltage mineral flame-retardant fireproof cable consists of a plurality of cable cores, filler and a flame-retardant outer jacket, wherein the cable cores are arranged inside the flame-retardant outer jacket, each cable core respectively and successively consists of a conductor, a conductor shielding layer, an insulating layer, an insulating shielding layer and a metal shielding layer from inside to outside, the filler fills between the cable core and the flame-retardant outer jacket, and the flame-retardant outer jacket successively consists of an insulating layer, a flame-retardant cooling layer, a fireproof mica tape, an armored layer and a halogen-free low-smoke flame-retardant jacket from inside to outside. The flame-retardant filler is arranged between an outer protection layer and the internal core, and the outer protection layer comprises an environment-friendly flame-retardant cooling layer, the armored layer and the flame-retardant outer jacket, so that the contradiction between the electrical performance and fireproof characteristics of the medium-high-voltage fireproof cable is solved, and the cable not only has excellent electrical performance, but also has good fire resisting characteristics.

Description

technical field [0001] The invention relates to the technical field of fireproof cable production, in particular to a medium-high voltage mineral flame-retardant fireproof cable and a production method thereof. Background technique [0002] With the acceleration of social and economic construction in our country, fire-proof and fire-resistant power cables are widely used in high-rise buildings, subways, power plants, nuclear power plants, tunnels and other important places. The voltage levels are all below 1 kV, and some occasions that require medium and high voltage transmission and distribution have no safety performance because there are no medium and high voltage fire-resistant cables. Contents of the invention [0003] The invention provides a medium and high voltage mineral flame retardant and fireproof cable and a production method thereof to solve the problem of contradiction between the electrical performance and fire resistance of the medium and high voltage fire...
