WDZ-RYSP low smoke halogen-free flame-retardant stranded wire 2 * 1.5

Description :

　　Cableway communication cable execution standard: YD/T322-2013 HYAC_ Cableway cable - Cableway communication cable Purpose: HYAC Cableway cable - Cableway communication cable is suitable for communication lines of cableways, as well as for connecting to public network and dedicated network lines. The HYAC_ cableway cable suspension adopts the method of thickening rigid lines to increase the tension of the cable by more than 3 tons. The RVVP power line can also be added to the cable to make a composite cable, which is economical, practical, and easy to install and lay. The mechanical and electrical properties of self-supporting cables remain unchanged under environmental conditions of -30~C-60~C. Self supporting cable structure: Wire: Annealed bare copper wire, copper wire diameter of 0.4, 0.5, 0.6, 0.7, 0.8, 0.9mm. Insulation material: high-density polyethylene or ethylene/propylene copolymer, insulation color meets the full chromatographic standard. Insulated wire pair: Two insulated wires of different colors are twisted into pairs at different pitches, and a detailed chromatographic combination of HYAC cableway communication cable is used for identification. Self supporting cable core structure: Based on 25 pairs as the basic unit, cables exceeding 25 pairs are combined by unit, and each unit is equipped with a designated chromatographic unit zip tie for identification of different units. 100 pairs or more of cables are equipped with 1% spare pairs. Self supporting cable core wrapping tape: wrapped with polyester film tape. Self supporting cable shielding: Use rolled or non rolled metal tape to wrap the cable core longitudinally and overlap the two sides. The plastic film coated on the surface of the shielding tape is bonded to the protective layer, claiming to be the cable sheath: black low-density polyethylene. Self supporting cable suspension wire: The suspension wire is a 7-strand galvanized steel wire with nominal outer diameters of 6.3mm and 4.75mm, and its tensile strength is not less than 3000kg and 1800kg respectively. The suspension wire is coated with thermoplastic coating to prevent steel wire corrosion. Self supporting cable identification and length marking: There are sexual identification marks on the outer surface of the cable, with an interval of no more than 1m. The marking content includes: wire diameter, number of wire pairs, cable model, manufacturer's name code and manufacturing year. The length marking is marked in the table with an interval of no more than 1m
