Low-frequency cables with polyolefin insulation and moisturebarrier polyolefin sheath. Part 2 :Unit type, filled, moisture barrier polyethylene sheathed cables with copper conductors and solid or cellular insulation

This technical specification addresses low-frequency power cables designed with polyolefin insulation and moisture barrier systems, specifically focusing on configurations featuring copper cores. The document establishes detailed requirements for cables that incorporate solid or foam polyolefin insulation combined with a filling material in the moisture-retarding layer. It further defines the specifications for an outer sheath constructed from polyethylene, ensuring compatibility and performance under defined operational conditions. The text outlines the necessary physical and electrical characteristics, including dimensions, material properties, and testing procedures required to verify compliance. These guidelines are intended to support manufacturers in producing consistent cable products while providing users with a clear reference for quality assessment. The scope covers specific design elements relevant to underground and indoor installations where moisture resistance is critical. By setting uniform parameters for insulation thickness, shead strength, and moisture barriers, the document facilitates international harmonization in cable production and selection. All provisions aim to ensure reliable performance over the expected service life of the cable system.
