DJYPV computer cables are suitable for electronic computers and automation applications with rated voltages of 500V and below, requiring high interference resistance. The cable's ground conductor core insulation utilizes oxidation-resistant K-type B-class low-density polyethylene. Polyethylene offers high insulation resistance, excellent voltage resistance, low dielectric constant, and minimal dielectric loss due to temperature and frequency fluctuations. This material not only meets transmission performance requirements but also ensures a long cable life.

DJYPV 3*2*1.5 Computer Cable
DJYPV computer cables are suitable for electronic computers and automation applications with rated voltages of 500V and below, requiring high interference resistance. The cable's ground conductor core insulation utilizes oxidation-resistant K-type B-class low-density polyethylene. Polyethylene offers high insulation resistance, excellent voltage resistance, low dielectric constant, and minimal dielectric loss due to temperature and frequency fluctuations. This material not only meets transmission performance requirements but also ensures a long cable life.
To reduce crosstalk between circuits and external interference, DJYPV computer cables utilize a shielded structure. DJYPV computer cable shielding requirements vary depending on the application: shielding of twisted pairs, overall shielding of the twisted pair cable, and overall shielding after shielding of twisted pairs.
DJYPV computer cable shielding materials include round copper wire, copper tape, and aluminum/plastic composite tape. Shielded pairs provide excellent insulation performance, and potential differences between shielded pairs during use will not affect signal transmission quality. Product rated voltage (U0/U): 300/500V
Long-term operating temperature: 70°C
Ambient temperature during installation: -40°C for fixed installation, -15°C for non-fixed installation
Minimum bending radius: Less than 6 times the cable's outer diameter for unarmored cables; no less than 12 times the cable's outer diameter for cables with armor
Insulation resistance should be no less than 2500 MΩ·km after a 1-minute stable charge test at 500V DC at 20°C
DJYPV computer cables should have no disconnection between twisted pair shields and between twisted pair shields and the overall shield. Cable core-to-core and shield-to-shield tests should be conducted at 50Hz and 2000V AC for 5 minutes without breakdown.
