Computer cable belongs to electrical equipment cable, this cable is suitable for rated voltage 500V and below for high interference requirements of electronic computers and automation instruments. According to the requirements of different environments and devices, the cable insulation can be polyethylene, polyvinyl chloride, and crosslinked polyb.
The core insulation of the computer cable is made of low density polyethylene with good chemical stability. Polyethylene has high insulation resistance, good voltage resistance, small dielectric coefficient and medium loss affected by temperature and frequency, which can not only meet the requirements of transmission performance, but also ensure the service life of the cable.

Computer cable models commonly used are:
DJYVP polyethylene insulated braided total shielding polyvinyl chloride sheathed computer cable
DJYPV polyethylene insulated braided sub-shielded polyvinyl chloride sheathed computer cable
DJYPVP polyethylene insulated braided sub-shielding and total shielding polyvinyl chloride sheathed computer cable
DJYVP2 polythene insulated copper with shielding polyvinyl chloride sheathed computer cable
DJYP2V polythene insulated copper with subshield polyvinyl chloride sheathed computer cable
DJYP2VP2 polyethylene insulated copper tape subshield and total shield PVC sheathed computer cable

Shielding computer cable characteristics
1. Rated voltage (U0/U):300/500V
2. Long-term operating temperature is 70℃
3. The ambient temperature during laying shall not be lower than: -40℃ for fixed laying and -15℃ for non-fixed laying
4. Bending radius: the unarmored layer should be less than 6 times the outer diameter of the cable, and the cable with armored layer should be not less than 12 times the outer diameter of the cable
5. At 20℃, the insulation resistance should not be less than 2500MΩ·Km after stable charging for 1min at 500V DC voltage test
6. There should be continuous routes between each pair of stranding shields and between the pair of stranding shields and the total shield
Between the core and the core of the cable and between the shields should be subjected to 50HZ, AC 2000V voltage test for 5 minutes without breakdown

Shield computer cable advantage
1. Mechanical properties: The computer cable uses the fifth type of soft conductor, the cable is soft and durable
2. Shielding performance: Computer cable has double-layer shielding performance, good shielding effect, high anti-static and anti-electromagnetic interference effect
3. Electrical performance: The computer cable uses PE as an insulating material, the dielectric constant is stable, and the working capacitance is stable
4. Flame retardant performance: the sheath is made of flame retardant PVC or low smoke halogen free, good flame retardant performance

Product use
