Cable sleeve

B1571Cable sleeve Features:1.snap-in type, easy installation, by snap locking the two ends together.2.built-in creepage growth unit increases creepage distance and improves insulation property.3.it can built-in sealing glue to strengthen sealing effect and improve the pressure level.4.excellent weather resisting property and insulation property; creepage-proof, wear-resistant, ultraviolet-resistant and aging-resistant.5.quick and easy to install.6.emergency repairsApplications1.Applicable to insulation and protection for contact networks carrier cable,supply line,positive feeder,FL parallel feeder under electrification railway cross-line building of 27.5kv/50HZ single-phase alternating current.2.applicable to insulation for electric railways catenary wire,electric power lines, positive feeder and reinforcing line of 27.5kv a.c. electrification railway crossing track building.3. mainly used for the purpose of insulation protection on overhead bare wires of 1KV to 35kv in city net and rural net:1) the shorter distance between overhead conductors and running tunnel,buildings,woods, and rivers;2)the safe distance between the power lines and other weaknesses lines(communication,light,radio,etc) is hard to guaranteed. In order to ensure power system security operation, and to effectively resolve unshift wire,the cable line cover can resolve the problem that safe distance between the electric power lines and distribution lines weren’t long enougth. Especially by using the cable line cover without influencing construction and project cost.4.mainly used in bare wires passing over woods,buildings,tunnels and rivers,etc.to enhance the insulation protection and prevent the short circuit.5.used in transportation of oiling switch on column and the part of city leader line to enhance the insulation protection.6.insulation protection for the part of the cord in the area of building fields and other engineering project closer to transportation line and distribution line.7.product specifications: inside diameter:14mm,18mm,20mm,28mm,38mm.8.color:red,yellow,green,black.9.working conditions:-40 80°C.Technical data: Property Testing method Typical data Tensile strength GB/T 1040-92 ≥10Mpa Elongation at break GB/T 1040-92 ≥500% Dielectric strength GB/T 1408-89 20kv/mm Volume resistance GB 1410-2006 ≥1.0*1013Ω*cm Dielectric constant GB 1409-2006 ≤3.0 Flammability(Oi) GB/T 2406-1993 ≥27 Microtherm flexility(-40°C,4hrs) ASTMD 2671 No Crack Water absorption GB/T 1034-98 ≤0.5%
