Low-Frequency Wires and Cables with PVC Insulation and PVC Sheath - Part 2 : Equipment Wires, Single

This technical specification outlines the requirements for flexible electrical cables designed for equipment connections. It specifically addresses single-core cables featuring insulation and sheathing made from polyvinyl chloride compounds. The document details material properties, construction tolerances, and dimensional characteristics essential for ensuring safety and performance in low-frequency applications. It covers aspects such as electrical resistance, voltage ratings, and mechanical durability under defined operational conditions. The scope is limited to single conductors used within machinery and fixed installations where flexibility and resistance to environmental factors are required. Manufacturing processes and testing methodologies are described to verify compliance with specified parameters for insulation thickness, conductor cross-section, and outer sheath integrity. These guidelines facilitate the production of cables suitable for specific industrial and commercial uses where standard rigid cabling is not appropriate. The text provides a framework for quality assurance during the design and fabrication stages, ensuring consistency across different production batches.
