Products Description
XLPE (Cross-Linked Polyethylene) insulated underground cables are electrical cables used for transmitting power underground, known for their enhanced thermal, electrical, and mechanical properties. The structure includes a conductor, XLPE insulation, screening, and an outer protective sheath. These cables offer high thermal resistance, excellent electrical properties, chemical resistance, mechanical strength, flexibility, and longevity. They are commonly used in power distribution, industrial installations, substations, and renewable energy systems. Installation requires careful planning and protective measures, with regular maintenance to ensure integrity. They must comply with international standards and local codes for safety and performance.
