Model Number: SB-WMPG SERIES Working temperature: -55ºC ~ 125ºCShrink ratio: 2:1 StructureBus-bar heat shrinkable protection tube adopts cross-linked and environmental friendly polyolefin material. It restricts the hazardous substance in PBB,Website:http://www.fiberglasssleeving.net, PBBD, PBBE and other heavy metal, and supplies high dielectric strength and voltage withstand performance. It prevents bus-bar from chemical corrosion effected by strong acid, alkali, salt etc. It also has environmental friendly, flexible, flame retardant, soft performance.             UsageIt is mainly used in dielectric and mechanical protection, joints and terminals.Characteristics1.Shrink temperature: 84ºC ~ 125ºC2.Environmental, flexible, flame retardant, softStandards1) GB/T 1059-2007                   2) RoHS approvalSpecificationPropertyUnitStandardTest MethodTensile StrengthMPA≥10.4(before aging)GB/T 1040      130ºC *168hrs≥7.3(after aging)Elongation%≥300(before aging)GB/T 1040; GB/T7141      130ºC*168hrs      ≥100(after aging)Heat Shock-no sticking; no crackingJB 7829appendixD.(160ºC*4hrs)Cold Blend-no cracking-30ºC*4hrsBreakdown StrengthKV/mm≥25GB/T 1408.1Volume ResistivityΩ. cm≥1×1014GB/T 1410Longitudinal Change%≥50Off-center%≤30UL 224Flame Retardant-≥30GD/T 2406Water Absorption%≤0.5ISO 62-1980Dielectric WithstandKV/mm≥30kV.1minGB/T 1408.1Shore Hardness(Shore A)≤90GB 2401*This data is suitable for 10kv bus bar protection tube.
