<strong>WCSF</strong>Heat-<strong>shrinkable</strong> <strong>heavy</strong>-<strong>wall</strong> <strong>flame</strong>-<strong>retarded</strong> <strong>tubing</strong>for nuclear environments<strong>Raychem</strong> <strong>WCSF</strong> <strong>tubing</strong> is a <strong>heavy</strong><strong>wall</strong>,<strong>flame</strong>-<strong>retarded</strong>, <strong>heat</strong>-<strong>shrinkable</strong><strong>tubing</strong>. It is pre-coated with a hotmelt, radiation-resistant adhesive toprovide a positive environmental seal.It is designed for electrical insulatingup to 1000 V and general purposesealing applications where <strong>flame</strong>retardancy, radiation resistance andsevere environmental performanceare required.<strong>WCSF</strong> <strong>tubing</strong> is suitable for a widerange of jointing or connection applicationsfor Class 1E wire and cablesystems in accordance with IEEE 383.Each connection is individually insulatedand sealed. Additionally, thesleeves can also be used for a widerange of related applications includingsealing, overs<strong>heat</strong>h replacement andstrain relief throughout the plant.They can also be supplied as kits ofcomponents for specific applications.<strong>WCSF</strong> <strong>tubing</strong> is already qualified fora 60-year service life to take intoaccount the requirements of the thirdgeneration of nuclear power plants.The <strong>heat</strong>-shrinkability of TycoElectronics‘ <strong>Raychem</strong> <strong>WCSF</strong> <strong>tubing</strong>provides fast and easy installation,positive visual inspection and apre-engineered insulation thicknessto assure consistent installation.<strong>WCSF</strong> <strong>tubing</strong> is supplied under thecomprehensive Tyco Electronics´<strong>Raychem</strong> Quality Assurance Programmewith certified documentationto meet industry requirements forsafety related electrical equipment.<strong>WCSF</strong> properties Test method RequirementTensile strength ISO 37 8.2 N/mm 2 min.Ultimate elongation ISO 37 250 % min.Density ISO 1183/3 Method A 1.35 g/cm 3 max.Accelerated ageing 200 h at 175° C ISO 1881600 h at 150° CTensile strength ISO 37 7 N/mm 2 min.Ultimate elongation ISO 37 100 % min.Low temperature 4 hours at – 55° C ASTM D2671 no crackingflexibilityProcedure CFlammability ICEA S-19-81 Sec. 6. 19.6 self-extinguishing in < 1 minDielectric strength nominal <strong>wall</strong> IEC 60243/1+2 75 kV/cm min.thickness 2.5 mmVolume resistivity IEC 60093 1 x 10 13 Ωcm min.Water absorption ISO 60062 < 0.5 % after 24 h at 23° + – 2°CCorrosive effect 16 h at 135° C ASTM D2671 Procedure A no corrosionHeat ageing 200 h at 175° C <strong>Raychem</strong> internaland radiation followed by 50 Mrad test methodgamma-radiation(0.5 – 1.0 Mrad/h)followed by:Tensile strength ISO 37 5.5 N/mm 2 min.Ultimate elongation ISO 37 50 % min.Additional properties Further details are given in <strong>Raychem</strong> specification PPS 3010.
