Flame-retardant and high-temperature-resistant 5G cable

Abstract

The invention discloses a flame-retardant and high-temperature-resistant 5G cable, which comprises a core wire layer, a braided layer, a heat insulation rubber layer and a protective layer, which arearranged in a layered manner from inside to outside. Glass fiber powders are dispersed in the heat insulation rubber layer; the glass fiber powders have relatively high heat-resisting and heat-insulating properties, and can form air gaps in the heat insulation rubber layer, so that invasion of external heat can be well isolated after the heat insulation rubber layer is added; the bending strengthof the heat insulation rubber layer mixed with the glass fiber powders is improved; and the cable has higher flame-retardant and high-temperature-resistant performance, and can effectively isolate theinterference of temperature factors on the core wire layer.

Description

technical field [0001] The invention relates to the field of power cables, especially 5G cables. Background technique [0002] With the development of transmission technology, transmission technology has gradually entered the 5G era from the 4G era, and in the transmission of electromagnetic waves, 5G requires a significant increase in transmission rate, bandwidth, and frequency, and the accessories used in 5G also need to be improved accordingly. suitable for dissemination; [0003] Traditional cables are generally insulated through the heat-insulating rubber on the outermost layer and the braided layer in the middle layer, so as to prevent the influence of heat on the core wire layer. The traditional heat-insulating rubber and braided layer alone can no longer To meet the needs of 5G conduction, and the current flame retardant improvement for cables, although it can improve the temperature insulation and flame retardant performance to a certain extent, it may cause major ...

[0003] Traditional cables are generally insulated through the heat-insulating rubber on the outermost layer and the braided layer in the middle layer, so as to prevent the influence of heat on the core wire layer. The traditional heat-insulating rubber and braided layer alone can no longer To meet the needs of 5G conduction, and the current flame retardant improvement for cables, although it can improve the temperature insulation and flame retardant performance to a certain extent, it may cause major changes in the flexibility and other properties of the cable, which cannot meet the wiring requirements
