H05V-R and H07V-R cables are stranded copper PVC building wires specially designed for housing construction. With excellent performance and various specifications, they have become ideal choices for residential electrical wiring.​ Both cables adopt multi-strand copper conductors. The multi-strand stranded structure endows them with excellent flexibility, allowing them to bend and shuttle easily in complex scenarios such as pipe through ing in residential walls and ceiling wiring, reducing installation difficulty. At the same time, it enhances fatigue resistance and prolongs service life. The high-purity copper material ensures excellent conductivity, which can effectively reduce losses during current transmission and ensure stable power supply for various electrical equipment in the residence.​ The insulation layer is made of PVC material, which has reliable insulation performance, can effectively insulate current, prevent electric leakage accidents, and protect the safety of residents. PVC material also has good corrosion resistance and weather resistance, adapting to different environments in the residence such as humidity (such as kitchen and bathroom) and dryness, ensuring stable performance during long-term use.​ In terms of specifications, the two cables provide a variety of cross-sectional area options including 1.5mm², 2.5mm², 4mm², 6mm², 10mm², 16mm², 25mm², etc., which can meet different electricity needs in housing construction. 1.5mm² and 2.5mm² are suitable for lighting circuits and ordinary sockets, supplying power to lamps, TV sets, refrigerators and other equipment; 4mm² to 6mm² can be used for high-power electrical appliances such as air conditioners and electric water heaters; specifications of 10mm² and above can meet the power transmission needs of the main power inlet of the residence or large electrical appliances.​ H05V-R and H07V-R cables are widely used in housing construction. Whether it is the overall electrical wiring of new residences or the line transformation of old houses, they can play an important role. They comply with relevant electrical standards, are easy to install and have stable performance, providing safe and efficient power transmission solutions for residences, and are reliable wire products in housing construction.
