Science leh technology lama hmasawnna kal zelah hian power cable lama technology thar chhuah pawh a kal zel a ni. Traditional copper leh aluminum cable bakah hian superconducting power cable thar hian transmission efficiency sang zawk leh transmission hloh tlem zawk a pe a, nakin lawka power cable siamna tur hmasawnna kawng pawimawh tak a ni. Chubakah, smart grids siam chhuah hian power cable technology lama thil thar chhuah chhunzawm zel a thlen mek bawk. Wireless power transmission leh visible light communication ang chi technology te hian power cable hmanna tur kawng thar a hawng dawn a ni.
