Problems solved by technology

The local telephone cable can be used for the transmission of telephone and voice, and the common coaxial cable can be used for watching Internet TV and high-definition TV. influence, mutual interference
[0003] Due to the limitations of the above-mentioned structure and wiring of the cables, the influence of electromagnetic radiation and capacitive coupling at high frequencies becomes more and more prominent, seriously affecting the electrical performance of each cable
These effects will lead to different degrees of influence on the family's Internet access speed, telephone call quality, and high-definition picture clarity after the integrated wiring of each cable is installed at the home. After heating and heating, it is easy to cause the sheaths of the cables to stick to each other, causing broken skins, or even leakage, burning, and eventually causing a fire

Abstract

The invention discloses a multifunctional cable for integrated power and data transmission. The insulating layer covers the power copper wire, the inner sheath layer covers the insulating layer, the shielding insulating layer covers the data copper wire, and the single-sided aluminum foil layer covers the shielding. Insulation layer, polyester tape layer covering inner sheath layer, single-sided aluminum foil layer and filling rope, double-sided aluminum foil layer covering polyester tape layer, flame-retardant layer covering double-sided aluminum foil layer, outer sheath layer covering resistance burning layer. Through the above-mentioned method, the multifunctional cable for integrated power and data transmission adopted in the present invention improves the reflection and absorption of high-frequency electromagnetic waves, improves crosstalk and signal attenuation, and also improves the cross-linking strength of the base material, and has a relatively high performance. Excellent tensile and tear strength physical and mechanical properties, thermal stability has been greatly improved in the manufacturing process.

Description

technical field [0001] The invention relates to the field of hybrid cables, in particular to a multifunctional cable integrating power and data transmission. Background technique [0002] In our existing integrated wiring system, 4 pairs of ordinary digital cables are generally used for Internet access and data transmission. The local telephone cable can be used for the transmission of telephone and voice, and the common coaxial cable can be used for watching Internet TV and high-definition TV. influence and interfere with each other. [0003] Due to the limitations of the above-mentioned structure and wiring of the cables, the influence of electromagnetic radiation and capacitive coupling becomes more and more prominent at high frequencies, seriously affecting the electrical performance of each cable. These effects will lead to different degrees of influence on the family's Internet access speed, telephone call quality, and high-definition picture clarity after the integr...
