High Temperature and Thermal Stress<\/b><\/h2>\n<h3><b>Presented Issue<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Exposure to very high temperatures is one of the major drawbacks of electrical insulation. Industrial machines, motors, and power distribution systems generally give out a lot of heat. If insulation materials are subjected to temperatures higher than their limits, they may become degraded, break, or even get melted.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Continuous thermal stress can also weaken the insulation dielectric strength capacity, thus raising the failure hazard.<\/span><\/p>\n<p>For high-temperature applications, choose <a href=\"https:\/\/www.harnawainc.com\/staging\/7496\/aramid-paper\/\">high temperature insulation paper<\/a> to improve thermal protection.<\/p>\n<h3><b>How to fix it?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Some of the measures to be taken against high-temperature issues are:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Adopt heat-resisting insulation materials like PTFE, silicone, or fiberglass<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Maintain good airflow around cables and equipment<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Never overload the circuits<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Use thermal insulation barriers or protective sleeves<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Determining the temperature rating of the insulation is the primary step in avoiding thermal damages.<\/span><\/p>\n<h2><b>2. Moisture and Water Ingress<\/b><\/h2>\n<h3><b>Presented Issue<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Moisture is an extremely harmful factor for electrical insulation. Once water manages to get inside the cable, it can cause the metal parts to get oxidized, the insulation to become ineffective, and even lead to short circuits. This situation is often encountered in outdoor equipment, underground cables, or areas with high humidity.<\/span><\/p>\n<h3><b>How to fix it?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">One can avoid getting wet issues by:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Going for waterproof or moisture-resistant cables<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Ensuring the cable is properly sealed and using appropriate glands<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Heat shrink tubing is a great tool for insulation as well as sealing<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Never expose the cables to standing water<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Furthermore, cables with higher IP ratings offer better resistance to water ingress.<\/span><\/p>\n<h2><b>3.
