THE GLOBAL PUSH FOR EFFICIENCY<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Worldwide, the industrial cable market is prioritizing solutions that reduce total project costs. A recent study highlighted that&nbsp;<strong>labor can account for up to 60-70% of total installation costs<\/strong>. Choosing cables that enable faster installation, like RV-K designs, is no longer a luxury but a strategic necessity to stay competitive on a global scale.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"planning-your-next-cable-project\"><\/span>PLANNING YOUR NEXT CABLE PROJECT?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When specifying cables for your next tender or project, defaulting to &#8220;NYY&#8221; cable can lead to receiving a less performance cable.
