DJYPVP/DJYVP computer cable, polyethylene insulated twisted copper wire braided individual shielding and general shielding PVC sheathed computer shielding cable, generally used for laying indoors, cable trenches, pipelines, direct buried ground and other places requiring electrostatic shielding. It adopts structural forms such as twisted pairs, paired screens, and total screens (or three-wire combination, group shielding, and group screens), and has the characteristics of low dielectric loss, strong signal transmission ability, and good anti-interference performance. Computer cables have high performance. Anti-static and anti-electromagnetic interference effects; suitable for detection and control computer systems or automatic control devices in power stations, mines, metallurgy, petrochemical and other departments, used to transmit weak analog signals and digital signals, and on general industrial computers. Computers The cable puts more emphasis on the shielding effect and has stronger anti-interference performance. Most of them adopt the method of sub-shielding + total shielding. In order to reduce mutual crosstalk and external interference between circuits, the computer cable adopts a shielded structure. There are three kinds of shielding materials: round copper wire, copper tape, aluminum tape/plastic composite tape. The shielded pair and the shielded pair have good insulation performance. If there is a potential difference between the shielded pair and the shielded pair during use of the cable, it will not affect the transmission quality of the signal. This product is suitable for the connection of electronic computers, testing instruments and meters with a rated voltage of 300/500v and below, which require high anti-interference performance.Product features: 1. Shielding performance: DJYPVP cable has double-layer shielding performance, and the shielding effect is good; 2. Electrical performance: the cable uses PE as the insulating material, with stable dielectric constant and stable working capacitance; 3. Flame retardant performance: the sheath is made of Flame retardant PVC or low-smoke halogen-free material, good flame retardant performance. Use characteristics and operation laying conditions:, (1) Product rated voltage (U0/U): 300/500v; (2) Long-term working temperature is 70°C; (3) The ambient temperature during laying is not lower than: fixed laying temperature -40 ℃, non-fixed laying -15℃; (4) Small bending radius: no armored layer should be no 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.
