Scope

Scope: This document specifies the requirements, inspection rules, marking, packaging, transportation, and storage of electric trace-resistant polyolefin sheathing materials for ADSS optical cables, and describes the corresponding test methods. This document applies to the production, inspection, and sales of electric trace-resistant polyolefin sheathing materials (hereinafter referred to as "electric trace-resistant sheathing materials") used in ADSS optical cables (all dielectric self-supporting optical cables) installed in areas with a space potential greater than 12 kV, which are made from polyolefin resins as the main raw material and various functional additives, and are produced by melt blending and extrusion granulation. Main technical content: 4.1 Appearance: The electric trace-resistant sheathing materials should be in the form of granules, with a diameter not exceeding 5 mm and a height of 2 mm to 4 mm. The granules of the electric trace-resistant sheathing materials should be of relatively uniform size, have a smooth surface, no impurities, and no more than three consecutive granules. 4.2 Physical and mechanical properties and electrical performance: The physical and mechanical properties and electrical performance of the electric trace-resistant sheathing materials should comply with the requirements specified in Table 1. 4.3 Environmental protection requirements: When the user has environmental protection requirements, the content of restricted substances in the electric trace-resistant sheathing materials should comply with the provisions of Table 2.
