Cable Conductor Wire Underground Secondary Specification Document

This specification document defines the technical requirements for underground secondary cable conductor wire for GRU's five-year wire and cable procurement contract. The specification establishes detailed performance standards for cable conductor wire used in underground secondary distribution systems, including requirements for conductor material composition, insulation properties, jacket specifications, and environmental resistance. The document addresses multiple conductor configurations and sizes to accommodate various distribution applications, with particular emphasis on durability in underground installations and compliance with industry standards. Specifications include requirements for tensile strength, elongation, insulation thickness, flame resistance, and ozone resistance to ensure reliability in diverse soil conditions and climate environments. The technical parameters outlined establish minimum performance benchmarks that supplier products must meet or exceed to qualify for inclusion in GRU's supplier contract.

The specification document serves as a technical reference standard for evaluating potential suppliers' cable products during the procurement evaluation process. This document does not independently establish pricing, delivery terms, or contract award information but rather provides the engineering and performance criteria necessary for suppliers to determine product compatibility with GRU's requirements. Compliance with these specifications is mandatory for suppliers bidding on the wire and cable contract groups, ensuring that all qualified suppliers can deliver products meeting GRU's operational and safety standards for underground secondary distribution applications.
