DC Power Cable 216mm² and 210mm² are 2-core single-phase aluminum core power cables, specially designed for house wiring, which can meet the power transmission needs of household DC electricity scenarios.​ In terms of materials, the conductor is made of aluminum core. Although its conductivity is slightly inferior to that of copper core, it has lower cost and lighter weight, which is suitable for the load demand of house wiring. The cable insulation layer usually uses materials with good temperature resistance and insulation performance, such as PVC (polyvinyl chloride), which can ensure electricity safety and avoid risks such as electric leakage. The 2-core design is suitable for single-phase circuits, which can transmit current and form a loop respectively, meeting the power supply needs of DC electrical appliances in the home.​ In terms of specifications, the 210mm² cable has moderate current-carrying capacity and is suitable for low-power DC equipment in the home, such as DC lamps and small DC chargers; the 216mm² cable has larger current-carrying capacity and can be used for DC appliances with slightly higher power, such as DC air conditioner indoor units and DC water heaters. Both cables meet the safety standards for house wiring, are easy to install, and can provide stable support for household DC electricity use.
