Flame retardant armored computer cables are suitable for electronic computers and automation connection cables with high anti-interference requirements for rated voltage of 500V and below. The insulation of the cable ground wire core is made of K-type B-class low-density polyethylene with oxidation resistance. Polyethylene has high insulation resistance, good voltage resistance, low dielectric coefficient, and low dielectric loss. It is suitable for computer and automation connection cables with high anti-interference requirements and rated voltage of 500V and below. The insulation of the cable ground wire core is made of K-type B-class low-density polyethylene with oxidation resistance. Polyethylene has high insulation resistance, good voltage resistance, low dielectric coefficient, and minimal influence of temperature and frequency on dielectric loss. It not only meets the requirements of transmission performance, but also ensures the service life of cables. Conductors are all three types of conductors.

Rated voltage of the product (U0/U): 300/500V. Long term working temperature is 70 ℃. When laying, the ambient temperature should not be lower than -40 ℃ for fixed laying and -15 ℃ for non fixed laying. The bending radius is very small. The non armored layer should be less than 6 times the outer diameter of the cable, and the cable with armored layer should be no less than 12 times the outer diameter of the cable. At 20 ℃, the insulation resistance should not be less than 2500M Ω · Km after stable charging with a DC 500V voltage test for 1 minute. There should be no open circuit between each pair of twisted shields, as well as between the pair of twisted shields and the total shield. The core and core of the cable, as well as between the shields, should withstand 50HZ. The AC 2000V voltage test should be conducted for 5 minutes without breakdown
