Three Key Indicators for Quality Inspection of Wires and Cables

Selecting qualified wire and cable products is crucial to ensuring the safety of people’s production and daily life. For ordinary consumers, in addition to learning how to choose qualified wire and cable products, it’s also essential to understand the basic monitoring knowledge related to wires and cables. In terms of wire and cable quality testing, the following key indicators are particularly important: Insulation Resistance Testing: Insulation resistance is an important indicator reflecting the insulation characteristics of wire and cable products. It is closely related to the product’s dielectric strength, dielectric loss, and the gradual degradation of insulation materials under operating conditions. For communication cables, excessively low interwire insulation resistance can also lead to signal attenuation in the circuit.

The wire and cable industry is enhancing its quality standards and strengthening self-regulation and compliance.

In order to earnestly cooperate with the government’s special supervision and inspection of wire and cable manufacturers, in line with the national strategy of building a country strong in quality, and to fully enhance the industry’s quality supply level and assurance capabilities, strengthen self-regulation and compliance, assume social responsibilities, safeguard industry interests, promote quality improvement and efficiency enhancement, and foster the healthy development of the industry, the Wire and Cable Branch of the China Electrical Equipment Industry Association hereby issues the following initiative to all its members as well as all industry organizations and practitioners: 1. Strictly abide by national laws and regulations, conscientiously implement all relevant provisions on national industrial policies, industrial access requirements, and industry management, and voluntarily uphold social ethics and good public order. We shall uphold the principle of “integrity first, quality foremost.”

Cable Procurement Guide

Cable procurement is an important task that requires careful consideration and planning. Here are some guidelines for cable procurement:

The fiber optic cable industry is encountering a favorable market opportunity.

The State Council Emergency Response Center has issued an “Urgent Notice on Preparing Post-Disaster Recovery and Reconstruction Plans,” calling on all relevant localities to develop such plans. Among these, the priority for infrastructure restoration and reconstruction includes power grids, highways, railways, and other critical systems. For the optical cable and cable industry, this represents yet another excellent market opportunity. According to the spirit of the State Council’s Executive Meeting held on February 13, in order to effectively carry out post-disaster recovery and reconstruction efforts, the Emergency Command Center recently issued the “Urgent Notice on Preparing Post-Disaster Recovery and Reconstruction Plans,” urging all relevant localities to promptly plan and deploy resources, coordinate human, material, and financial resources, and swiftly restore essential infrastructure to the greatest extent possible.

Grid construction will bring a share of the pie to the cable industry.

According to the “11th Five-Year” power grid development plan formulated by State Grid Corporation, the company’s total investment in power grid construction will reach approximately 850 billion yuan, while the nation’s total investment will exceed 1 trillion yuan. The new round of large-scale power grid and urban grid construction and renovation is once again sparking a surge in expansion within the wire and cable industry. Across the country, production lines for medium- and high-voltage cross-linked cables are being launched. During the “11th Five-Year” period, State Grid Corporation will add 60,000 kilometers of transmission lines with voltage levels of 330 kV and above, as well as 300 million kVA of transformer capacity. The Southern Power Grid plans to complete and put into operation 15,651 kilometers of 500 kV AC transmission lines with a transformer capacity of 61.75 million kVA; it has already completed...
