3 Core 2.5mm² Flexible PVC Insulated Cable 300/500V is a multi-core cable widely used in low-voltage electrical systems, designed specifically for wiring scenarios requiring a certain degree of flexibility. Its core structure includes 3 conductors with a cross-sectional area of 2.5mm², each made of high-purity stranded copper. Stranded by multiple fine copper wires, it not only ensures excellent conductivity (conductivity ≥58MS/m) but also significantly enhances the flexibility of the cable, adapting to installation environments with frequent bending and folding, such as internal wiring of household appliances, office equipment connections, and small mechanical circuits.​ The cable has a rated voltage of 300/500V, suitable for low-voltage power distribution systems with AC 50Hz or 60Hz, and can safely carry a continuous current of approximately 24A (at an ambient temperature of 30℃), meeting the power requirements of most small and medium-sized electrical equipment. Each conductor is wrapped with a temperature-resistant and wear-resistant PVC insulation layer with a uniform thickness (about 0.8mm), which has good dielectric properties and can withstand a 2kV power frequency withstand voltage test, effectively preventing the risk of short circuits between core wires. At the same time, the PVC material has flame-retardant properties (complying with UL94 V-0 standards), which can self-extinguish quickly after the open flame is removed, reducing the risk of fire spread.​ The overall design of the cable focuses on practicality and safety: the 3 insulated core wires are arranged in parallel or twisted, and wrapped with a unified PVC sheath. The sheath is mostly gray or black, which not only enhances the overall structural strength but also resists external mechanical impact, moisture, and chemical corrosion. In addition, the core wires are identified by different colors (such as brown, blue, yellow-green), which is convenient for distinguishing phase wires, neutral wires, and ground wires during installation, in line with international electrical specifications, and reduces wiring errors.​ In terms of application scenarios, this cable, with its flexibility advantage, is widely used in power supply for mobile equipment (such as electric tools, stage lighting), concealed or exposed wiring in buildings, elevator trailing cables, internal connections of automation equipment, etc. Its operating temperature range is -15℃ to 70℃, which can adapt to most indoor and outdoor environments, and has passed multiple international and domestic standard certifications such as IEC 60227 and GB 5023, ensuring stable performance during long-term use.​ In conclusion, the 3 Core 2.5mm² Flexible PVC Insulated Cable, with its balanced conductivity, flexible installation characteristics, and reliable safety performance, has become an ideal choice for connecting small and medium-sized equipment in low-voltage electrical systems, meeting the dual needs of practicality and safety.
