The reduced weight means less structural support is needed for the transmission towers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">Residential Wiring:<\/mark><\/strong> In the past, aluminium was used in residential electrical wiring during the 1960s and 1970s due to its cost advantage. However, due to issues with expansion and contraction, which could lead to lose connections and potential fire hazards, its use in residential wiring has become less common. Newer alloys and installation techniques have mitigated these issues, but it is still a factor to consider.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-vivid-cyan-blue-color\">Large-Scale Power Distribution:<\/mark><\/strong> For large buildings, industrial plants, and commercial facilities, aluminium wiring is used for power distribution. The cost savings and lighter weight are significant benefits in these contexts.<\/p><div class=\"pai-ad\" style=\"min-height:250px;visibility:hidden;\"><span style=\"display: block; text-align: center; font-size: 10px; margin: 0 0 10px 0; color: #999999;\">Ads<\/span>\r\n<!-- Display-300x250-1 -->\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:inline-block;width:300px;height:250px\"\r\n     data-ad-client=\"ca-pub-3838168351244230\"\r\n     data-ad-slot=\"9933646018\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Where Aluminium Wire is Used<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-black-color\">Overhead Power Lines:<\/mark><\/strong> Aluminium wire is predominantly used in overhead power lines for both transmission and distribution.
