Temperature resistance ensures that the cable works stably in an environment of -30°C to 70°C, adapting to temperature changes in different areas of the residence (such as stuffy ceilings in summer and cold balconies in winter). Flame retardancy complies with relevant national standards, and it can self-extinguish when exposed to fire, avoiding the spread of flames and adding a guarantee for residential electricity safety.​ In terms of application scenarios, relying on the advantages of 3-core integration and 2.5mm² specification, this cable fully covers the needs of house wiring and small electrical installation. In new houses, it can be used as the main wiring for lighting and ordinary sockets in living rooms and bedrooms. The three cores correspond to the live wire, neutral wire, and ground wire respectively, meeting the safe electricity use specifications. In areas such as kitchens and bathrooms, it can be used to connect the power supply circuits of small and medium-sized household appliances (such as dishwashers and electric water heaters). The combination of solid copper conductors and flame-retardant PVC can cope with humid and high-temperature environments. In old house renovations, it can directly replace old cables. Through the 3-core design, the number of wall grooves is reduced, and damage to the original decoration is minimized. In addition, this cable is also suitable for electrical installation in small commercial spaces (such as convenience stores and small offices) as the power supply line for lighting and cash register equipment. The 100m roll can flexibly adapt to the wiring length needs of different spaces.​ In terms of construction and safety characteristics, the solid copper conductor of the cable is easy to strip and wire, compatible with common terminals, sockets, and switches. Installation can be completed without special tools, improving construction efficiency. The 3-core parallel arrangement structure is not easy to entangle when threading through conduits, and can easily pass through narrow wall pipes or ceiling gaps. The surface of the insulation layer is smooth, with little friction with the inner wall of the conduit, reducing the resistance of threading. In terms of safety, in addition to flame retardancy and insulation performance, the cable also passes strict quality inspections (such as conductor resistance test, insulation withstand voltage test, and flame retardant test) to ensure compliance with national electrical safety standards. During use, problems such as insulation aging and conductor breakage are not easy to occur, providing long-term and reliable protection for the residential electrical system.
