This underground cable adopts a 3X25+1X16mm² specification design, suitable for 0.6/1kv voltage level, and is a reliable choice for underground power distribution scenarios.​ Three 25mm² main cores are responsible for three-phase power transmission, and one 16mm² auxiliary core serves as a ground wire, forming a complete power distribution circuit. The current-carrying capacity of the main cores is suitable for small and medium-sized power consumption scenarios, such as underground power distribution main lines in residential communities and power supply for equipment in small industrial parks. The ground wire ensures electrical safety through reliable grounding and quickly conducts current away in case of electric leakage.​ The XLPE insulation layer is one of the core advantages. It has strong temperature resistance and stable insulation performance, and can resist the impact of underground humidity, soil corrosion and other environmental factors. Even in the underground environment with temperature changes or slight chemical erosion, it can still maintain insulation integrity and extend the service life.​ The cable is specially designed for underground laying, with a compact structure and certain mechanical strength, which can withstand soil pressure and slight external impact. During production, the thickness of the insulation layer and the purity of the conductor are strictly controlled to ensure stable operation in scenarios such as underground power distribution and equipment grounding, providing safety guarantee for power transmission.
