Cis Hta Cable 18/30kv 3X1X120mm2 240 mm2 Al/XLPE/HDPE Direct Burial Cable Underground Cable​ The Cis Hta Cable, rated at 18/30kv and available in 3X1X120mm² and 3X1X240mm² configurations, stands as a high-performance underground power transmission solution engineered for direct burial applications. Featuring an aluminum conductor, XLPE insulation, and an HDPE outer sheath, this cable combines robust construction with efficient power delivery, making it ideal for medium to high-voltage underground networks.​ The two conductor sizes cater to varying load demands: 3X1X120mm² for medium-capacity power distribution in urban or industrial zones, and 3X1X240mm² for high-current applications such as connecting substations or powering large industrial complexes. The aluminum conductor offers excellent conductivity with a lightweight design, reducing installation complexity while ensuring minimal power loss.​ XLPE insulation provides superior dielectric strength, thermal stability (-40°C to 90°C), and resistance to moisture and chemicals—critical for underground environments. The HDPE outer sheath adds a durable layer, enhancing resistance to abrasion, soil corrosion, and mechanical impact during installation and operation.​ Designed for direct burial, the cable eliminates the need for protective conduits, lowering installation costs. It complies with international standards for underground high-voltage cables, ensuring reliability in diverse soil conditions, including clay, sand, and rocky terrain. Whether for urban infrastructure, industrial parks, or renewable energy projects, this Cis Hta Cable delivers safe, long-term performance in underground power transmission.
