These cables serve as the foundation for power distribution systems requiring voltages above the extended low voltage range (1.9\/3.3kV) but below the higher distribution voltages (6.35\/11kV).

Such cables would be well suited to fixed installation power distribution, and providing power to heavy-duty static equipment as their rigid construction limits the bend radius. Beyond fixed installations, 6.6kV is used extensively in Marine applications and mobile offshore units, where cables tend to be supplied with tinned copper conductors and sheathing materials suited to the environmental challenges.<\/p>\n                \n                <p class=\"citation\">Source: <a href=\"https:\/\/www.elandcables.com\/cables\/mv-armoured-xlpe-swa-pvc-lszh-cables\" rel=\"nofollow noopener noreferrer\" target=\"_blank\" class=\"source-ref\">Eland Cables &#8211; MV Armoured XLPE\/SWA Cables<\/a><\/p>\n                \n                <div class=\"lang-section spanish\">\n                    <p><span class=\"lang-badge lang-es\">Espa\u00f1ol<\/span><strong>Introducci\u00f3n a los Cables de Media Tensi\u00f3n 3.8\/6.6kV<\/strong><\/p>\n                    <p>La clasificaci\u00f3n de tensi\u00f3n 3.8\/6.6kV es un punto de entrada clave en la clasificaci\u00f3n de cables de media tensi\u00f3n (MT) y est\u00e1 m\u00e1s com\u00fanmente asociada con las normas brit\u00e1nicas, notablemente las especificaciones BS6622 y BS7835.
