Recent Industry Requirements<\/h3>\n<p dir=\"auto\">IEC 60502 series defines water-penetration tests (longitudinal, with 1 m water head and thermal cycles). IEEE 3150-2025 (published August 2025) specifically addresses testing methods for semi-conductive water-blocking tape in 110\u2013500 kV XLPE AC cables, focusing on properties that prevent buffer-layer ablation failures. Chinese industry standard YD\/T 1115.1-2023 covers telecommunications and optical-fibre applications. REACH &amp; RoHS compliance is mandatory for global supply.<\/p>\n<p dir=\"auto\">Recent field experience (2020\u20132026) shows that incomplete drying or excessive moisture content in the tape before sheathing can lead to white powder precipitation (sodium polyacrylate + aluminium corrosion products). This raises volume resistivity, lowers relative permittivity and thermal conductivity, and can initiate partial discharge between the tape and aluminium sheath\u2014resulting in local ablation of the buffer layer. Proper moisture control (&lt;9 %), correct overlap, and verified swelling performance after heat ageing (90 \u00b0C, 12 months equivalent) are therefore critical process controls.<\/p>\n<h3 dir=\"auto\">Application Guidelines and Process Considerations<\/h3>\n<ul dir=\"auto\">\n<li><strong>Medium- and high-voltage XLPE power cables<\/strong>: Semi-conductive tape applied over insulation screen, under metallic sheath; optional second non-conductive layer over wire screen.<\/li>\n<li><strong>Submarine \/ wet-location cables<\/strong>: Double-side high-swell grades combined with radial moisture barriers (Al\/PE laminate).<\/li>\n<li><strong>Optical fibre and hybrid cables<\/strong>: Thin non-conductive tape or yarn for interstitial filling.<\/li>\n<li><strong>Processing<\/strong>: Tape must withstand CV-line temperatures up to 230 \u00b0C without powder loss or dimensional change. Widths are slit from 8 mm to &gt;500 mm; core diameters typically 76\u2013150 mm.<\/li>\n<\/ul>\n<p dir=\"auto\">Common failure modes to avoid:<\/p>\n<ol dir=\"auto\">\n<li>Insufficient swelling height after ageing \u2192 incomplete sealing under pressure.<\/li>\n<li>High residual moisture \u2192 premature gelation or powder migration.<\/li>\n<li>Incorrect conductivity grade \u2192 equipotential disruption or dielectric stress.<\/li>\n<li>Mechanical damage during high-speed application \u2192 gaps that allow water tracking.<\/li>\n<\/ol>\n<h3 dir=\"auto\">Practical Recommendations for Cable Manufacturers and Specifiers<\/h3>\n<p dir=\"auto\">Specify tape by measured swelling performance after thermal ageing rather than nominal thickness alone. Verify volume resistivity and surface conductivity for semi-conductive grades under the conditions defined in IEEE 3150-2025. Maintain low incoming moisture and control application tension to avoid wrinkles or gaps. For critical HV circuits, combine longitudinal swellable tape with a continuous radial metallic or laminated moisture barrier.<\/p>\n<p dir=\"auto\">Water Blocking \/ Swellable Tape remains the most process-compatible and cost-effective solution for reliable longitudinal water blocking in modern XLPE, EPR and optical cable constructions. Proper grade selection and process control directly extend service life and reduce repair costs caused by moisture-induced failures.<\/p>\n<p dir=\"auto\"><strong>Demande d&#039;informations<\/strong> for detailed technical data sheets, custom slit widths, swelling test reports, or sample evaluation for your specific cable designs.<\/p>","protected":false},"excerpt":{"rendered":"<p dir=\"auto\">Ruban bloque-eau de qualit\u00e9 professionnelle (\u00e9galement connu sous le nom de ruban gonflant \u00e0 l'eau) fabriqu\u00e9 \u00e0 partir de tissu non-tiss\u00e9 en polyester \u00e0 haute r\u00e9sistance, impr\u00e9gn\u00e9 de polym\u00e8re superabsorbant (SAP).
