This article introduces House Home Cable and Xhhw, Xhhw-2 copper-core cables with specifications of 500, 600, 750, 1000 Kcmil (Mcm) under the 600V voltage level. These cables use copper as conductors, which have excellent conductivity and can reduce transmission losses.​ The rated voltage of 600V is suitable for the power demand of household and residential scenarios. Different Kcmil specifications correspond to different current-carrying capacities. 500 Kcmil is suitable for power supply of small and medium-power household appliances, and 1000 Kcmil can meet the electricity demand of large electrical appliances or residential main incoming lines. Xhhw is a cross-linked polyethylene insulated weather-resistant cable. Xhhw-2 has better temperature resistance on its basis, with a higher long-term working temperature, and can adapt to possible temperature fluctuations in residences.​ They are specially designed for families and residences, and can be used for indoor power distribution lines, electrical connections, etc. They are easy to install and have reliable safety performance, providing stable guarantee for household power supply and meeting the safety and efficiency requirements of residential electricity use.
