OF?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Within this article, we\u2019ll examine how electrical cables are made, the materials they are constructed from and the processes behind their manufacture.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"conductive-material\"><\/span>CONDUCTIVE MATERIAL<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Conductors are the core component within an electrical cable that is responsible for carrying electrical current. Typically, they are made from materials that have the highest level of conductivity, including copper and aluminium, being a crucial component in how an electrical cable is made.&nbsp;<br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"protective-insultaror\"><\/span>PROTECTIVE INSULTAROR<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Insulation within an electrical cable is a protective material that encases the conductor, designed to prevent electric current from flowing, ensuring that the current is confined to the conductor. These are commonly made from <a title=\"rubber cables\" href=\"https:\/\/www.topcable.com\/low-voltage-cables\/rubber-cables\/\" target=\"_blank\" rel=\"noreferrer noopener\">rubber<\/a> and plastics like <a title=\"power cables\" href=\"https:\/\/www.topcable.com\/low-voltage-cables\/power-cables\/\" target=\"_blank\" rel=\"noreferrer noopener\">PVC<\/a>, as they act as insulators and prevent current from escaping.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"what-metals-are-used-to-manufacture-electrical-cables\"><\/span>WHAT METALS ARE USED TO MANUFACTURE ELECTRICAL CABLES?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Electrical cables are mainly made of copper. This is the best conductor of electricity, although there are also types of cables that use aluminium or other types of materials of different qualities depending on how it is made.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"copper\"><\/span>COPPER<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Copper cable has excellent conductive properties, allowing electricity to flow with efficiency and minimal energy loss; therefore it is commonly used as a conductor in electrical cables.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"aluminium\"><\/span>ALUMINIUM<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><a title=\"aluminium cables\" href=\"https:\/\/www.topcable.com\/low-voltage-cables\/aluminium-cables\/\" target=\"_blank\" rel=\"noreferrer noopener\">Aluminium cable<\/a> is lightweight and cost-effective as a conductor, therefore despite having lower conductivity properties than copper, it is often used as a more cost-effective alternative to copper.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"how-are-power-cables-made\"><\/span>HOW ARE POWER CABLES MADE?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p

explains how an electrical cable is made, from the initial drawing, through the choice of insulation, followed by the phase wiring, the auxiliary protection, the outer sheath and ending with quality control.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Plus other steps such as shipping and aspects of the manufacturing process that ensure it is sustainable and environmentally responsible.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"what-is-the-manufacturing-process-of-an-electrical-cable\"><\/span><strong>WHAT IS THE MANUFACTURING PROCESS OF AN ELECTRICAL CABLE?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The manufacturing process of a <a href=\"https:\/\/www.topcable.com\/medium-voltage-cables\/\" target=\"_blank\" rel=\"noreferrer noopener\">Medium Voltage<\/a> cable is divided into seven stages: <strong>incoming feed, polymer feed,
