The E-Yy, E-Y2y, E-Ayy, E-Ay2y, and E-A2y series power cables feature aluminum as the conductor core, with polyvinyl chloride (PVC) as the insulation material and a high-density polyethylene (HDPE) outer sheath, forming a power transmission solution with both conductive stability and environmental adaptability.​ Aluminum conductors reduce laying costs due to their lightweight advantage while maintaining good conductivity, meeting the needs of small to medium - power power transmission. The PVC insulation layer has excellent insulation and temperature resistance, which can effectively insulate current and adapt to a working environment of - 15℃ to 60℃; the HDPE outer sheath endows the cable with excellent weather resistance and impact resistance, with outstanding UV resistance and acid - alkali corrosion resistance, which can resist erosion from complex environments such as outdoor wind and rain, and humid soil.​ This series of cables has a compact structure and good flexibility, which is convenient for bending and laying, and is suitable for scenarios such as building power distribution, outdoor temporary power supply, and wiring of small industrial equipment. Its production complies with relevant standards, with high insulation resistance and reliable mechanical strength, enabling long - term stable operation, and it is a power transmission choice that balances economy and practicality.
