What cable is DJYPVP?

DJYPVP cable is a computer shielded cable, the full name of which is polyethylene insulated twisted pair copper wire braided sub-shielded and total shielded PVC sheathed computer cable,  Long-term working temperature of DJYPVP cable conductor: PVC has 70 ℃ and 105 ℃; 70 ℃ for polyethylene insulation; Cross-linked PVC insulation is 90 ℃.  The cable is allowed to be fixed and laid under the ambient temperature of - 40 ℃~50 ℃, and the ambient temperature during laying shall not be lower than 0 ℃. Cables with copper tape shielding structure, The bending radius during laying shall not be less than 12 times the outer diameter of the cable, and the bending radius of other cables during laying shall not be less than 6 times the outer diameter of the cable.

DJYPVP cable characteristics

1. Working temperature: generally not more than 70 ℃, low ambient temperature: fixed laying - 40 ℃. Non-fixed laying - 15 ℃;  2. General flame retardance shall comply with GB12666.2-90&dec bundle flame retardance shall comply with GB12666.5-90;  3. Rated voltage: U0/U: 300/500V;  4. Small bending radius: the cable without armor layer shall not be less than 10 times of the outer diameter of the cable, and the cable with armor layer shall not be less than 12 times of the outer diameter of the cable.  5. Executive standard of the product: Q/HHTZH002.4 (equivalent to British BS5308 standard), and the flame retardant shall comply with GB12666-90 standard.

Difference between DJYPVP and DJYPVRP cables

DJYPVRP multiple R represents soft core, DJ: computer cable code; Y: Polyethylene code of insulating material; P: Copper wire braid shield, this position represents split phase shield；5: PVC sheath material code; R: The cable conductor adopts five types of structure (flexible conductor);  P: Copper wire braided shield, this position represents the total shield (shield is also required after the assembly cable).  DJYPVP, DJYPVPR cable and other computer cables are suitable for electronic computers and automation connection cables with rated voltage of 500V and below and high requirements for anti-interference.  The "Research Institute of Cable and Cable Application Technology" mentioned that the core insulation of cable ground wire is made of K type B low density polyethylene with oxidation resistance. Polyethylene has high insulation resistance,  With good voltage resistance, low dielectric coefficient and low influence of dielectric loss temperature and variable frequency, it can not only meet the requirements of transmission performance, but also ensure the service life of the cable.  In order to reduce mutual crosstalk and external interference between loops, the cable adopts shielding structure. The shielding requirements of cables are adopted according to different occasions: twisted pair combination shielding.  The total shielding of the twisted pair cable and the total shielding after the twisted pair combination shielding. Shielding materials include round copper wire, copper tape, aluminum tape/plastic composite tape.  The shielded pair and the shielded pair have good insulation performance. If the potential difference between the shielded pair and the shielded pair occurs during the use of the cable, the signal transmission quality will not be affected.
