It is used as connection cable of inspection devices and instruments with high demand on interference resistant performance in computer network and control system. Executive standard:
Q/AE.J.04.030-2004 or BS5308 standard for reference Performance for Usage:
1. AC rated voltage U0/U: 300/500V. Long term working temperature of cable conductor is 70℃ & 105℃ for cable with PVC insulation, 70℃ for cable with PE insulation and 90℃ for cable with XLPE insulation.(XLPE insulation includes silane XLPE & irradiation XLPE insulation.)
2. Min. environment temperature is -40℃ for fixed laying and -15℃ for non-fixed laying. Environment temperature shall be no less than 0℃ for installing.
3. Min. bending radius allowed by cable is no less than 6 times that of cable OD for non-armored soft cable or braided shielding cable and 12 times that of cable OD for cable with metallic tape wrapped shielding or steel wire/steel tape armor. Type, Description and Definition Example: DJYP3VP3-32
32: Steel wire winding armor PVC outer sheath
P3: Aluminum-plastic compound tape wrapped general shielding
V: PVC inner sheath
P3: Aluminum-plastic compound tape wrapped individual shielding
Y: PE insulation
DJ: Series number of computer cable
