Bidding and tendering refer to a prevalent transactional method adopted for bulk commodity trading, project contracting in construction works, and procurement of service projects under market economy conditions. It constitutes a commercial transaction behavior encompassing two interconnected phases: tender invitation and bid submission. In critical sectors such as power engineering, construction engineering, and communication networks, cables, wires, lines, and multicore conductors serve as core components of infrastructure development. Their procurement and supply are facilitated through bidding mechanisms, which have evolved into a specialized and standardized market allocation system. With the continuous advancement of power infrastructure construction and the rapid growth of the new energy industry, the cable bidding market has expanded significantly. Its transaction mechanisms have matured progressively, playing a vital role in optimizing resource allocation, reducing project costs, and enhancing supply chain efficiency.
