XLPE: XLPE stands for Cross-Linked Polyethylene. It is a type of
insulation material used to cover the conductor. XLPE insulation
provides excellent electrical properties, thermal resistance, and
moisture resistance, making it suitable for high-voltage
applications.
Submarine Cable: This term specifies that the cable is designed for
underwater or subsea applications. It is intended to be installed
in marine environments such as oceans, seas, or lakes for the
transmission of electrical power over long distances underwater.
