Problems solved by technology

[0002] High-frequency cables are cables used to transmit high-frequency signals. Since the cables have distributed capacitance and distributed inductance, they can filter high-frequency signals and attenuate high-frequency signals. Therefore, for the transmission of high-frequency signals, distributed capacitance and distributed inductance are required. Small cables, whose insulation and sheath materials are polyvinyl chloride, cannot meet the needs of those who need to use in high temperature environments, and their firmness is not strong

Abstract

The invention discloses a fireproof and fire-resistant Litz wire high-frequency special cable, and the cable comprises a cable core, and is characterized in that the cable core comprises an I-shaped silicon rubber skeleton, and two sides of the silicon rubber skeleton are respectively provided with a conductor group; each conductor group comprises two Litz wire conductors formed by twisting a plurality of enameled wires, and the outer side of the litz wire conductor formed by twisting the enameled wires is coated with a silicon rubber insulating layer; the outer side of each conductor group is sequentially wrapped by a ceramic silica gel fireproof composite belt inner wrapping layer and a metal wire braided shielding layer from inside to outside, and the cable core is sequentially wrapped by a ceramic silica gel fireproof composite belt outer wrapping layer, a mica layer and a fireproof sheath layer. Both the insulating layer and the framework are made of silicone rubber materials with good high-temperature resistance, so the cable can be used in a high-temperature environment with the working temperature of 180 DEG C, and the use of the framework further meets the requirements of firmness and dragging resistance of the cable.

Description

technical field [0001] The invention relates to the field of cables, in particular to a fireproof and refractory Litz wire high-frequency special cable. Background technique [0002] High-frequency cables are cables used to transmit high-frequency signals. Since the cables have distributed capacitance and distributed inductance, they can filter high-frequency signals and attenuate high-frequency signals. Therefore, for the transmission of high-frequency signals, distributed capacitance and distributed inductance are required. Small cables, whose insulation and sheath materials are polyvinyl chloride, cannot meet the needs of those who need to use in high temperature environments, and their firmness is not strong. [0003] Polytetrafluoroethylene, commonly known as "Plastic King", is a polymer compound made of tetrafluoroethylene, which has excellent chemical stability, corrosion resistance, sealing, high lubrication and non-stickiness, electrical insulation and good Anti-ag...
