The power cord of lighting equipment is a power transmission connection line specially designed for various lighting devices, which undertakes the function of transmitting electrical energy from the power supply circuit to the lamp body. It is suitable for multiple lighting scenarios such as fixed installation, outdoor layout, and mobile operations, and is a basic supporting component to ensure the stable operation and electrical safety of the lighting system. The conductors of this type of power cord are mostly made of high-purity oxygen free copper multi strand twisted structure, which has stable conductivity, low line loss, and controllable temperature rise during long-term continuous power supply. It can adapt to the long-term operation characteristics of lighting equipment. The insulation and outer sheath materials are selected according to the usage scenario: environmentally friendly polyvinyl chloride (PVC) material is commonly used for indoor conventional lighting, and the wire body is flexible and smooth, making it easy to pass through pipes for wiring and internal wiring of lamps; Weather resistant modified PVC or rubber sheath is mostly used for outdoor and harsh environment lighting, which has the characteristics of ultraviolet resistance, rain resistance, high and low temperature resistance and aging resistance, and can adapt to complex working conditions such as outdoor temperature difference and wet dust. According to the core wire structure, it can be divided into two types: two core and three core. Two core wires are suitable for small LED lamps, decorative lighting and other products with double insulation; The three core wire is equipped with an independent grounding core wire, which is a standard configuration for metal shell lamps, high-power mining lamps, and outdoor floodlights, effectively preventing equipment leakage risks. The wire diameter specifications cover 0.5mm ² to 1.5mm ², with rated voltages mainly at 300/500V and 450/750V, which can correspond to different load requirements from low-power ambient lighting to high-power industrial lighting. Partial finished wire ends are pre installed with national standard plugs, waterproof connectors, or quick connect terminals, which can greatly improve on-site installation and replacement efficiency. The insulation strength of qualified lighting equipment power cords meets the standard, and the flame retardant performance meets the corresponding safety specifications. Bending and pulling are not prone to core breakage and sheath cracking, and long-term use is not prone to hardening or brittleness. The product is widely compatible with a full range of lighting equipment, including home ceiling lights, commercial flat panel lights, outdoor landscape lights, road lighting, factory industrial and mining lights, mobile emergency work lights, etc. It also takes into account multiple usage scenarios such as original factory assembly and engineering wiring, after-sales replacement, etc.
