Problems solved by technology

[0003] High-speed cables are mainly produced with materials such as foam insulation or low dielectric constant PP\PE\FEP. Although foam or PP / PE materials have a good low dielectric constant, they do not have flame retardancy and fire resistance. FEP materials It is a good fire-resistant low-dielectric constant material, but its cost is high. Foreign materials are 200 yuan / KG, and domestic materials are also 100 yuan / KG; and the dielectric constant of traditional flame-retardant cables reaches 2.8-3.2. The dielectric constant affects the size and signal attenuation of the product, which cannot effectively meet the upgrade characteristics of high-speed line products with low attenuation and high fire resistance
