Quality Control

Equipped with over 280 sets of world-class production machinery and more than 120 testing instruments, including imported high-end production lines and intelligent supervision systems, our facility represents industry-leading equipment and technology. The company primarily manufactures over 100 product types across three major categories, covering more than 40,000 specifications for cables up to 220 kV, including both high- and low-voltage power cables.
We focus on the development of multiple specialized products, with conductors featuring a maximum cross-sectional area of 2,500 mm², meeting the most demanding performance requirements.

Professional Inspection Teams and Precision Equipment

Every batch of raw materials undergoes comprehensive testing, including composition analysis, temperature resistance, and insulation performance, with zero tolerance for non-compliant materials. From procurement screening to warehouse acceptance, standardized controls throughout the entire process ensure that every metre of cable meets rigorous quality standards, providing a solid foundation for safety in subsequent production and operation.

Strict Quality Inspection

At the finished product stage, multi-dimensional sampling inspections are performed, covering electrical performance, mechanical properties, and environmental resistance. Specialized cables, including flame-retardant and fire-resistant types, undergo additional dedicated testing to ensure compliance with stringent safety requirements.
Our professional quality inspection team strictly adheres to national and industry standards, ensuring that non-compliant products never reach the market. Through rigorous monitoring at every stage of production, we safeguard the safety and reliability of power transmission and construction projects.

Advanced Material Technologyy

By employing specialized polymer materials, such as ultra-clean cross-linkable polyethylene, and integrating high-end manufacturing processes, the company ensures that core product performance characteristics—including insulation and shielding—remain at the forefront of the industry.

Multiple Professional Certifications

With over three decades of extensive expertise, the company has achieved excellence across all aspects of its operations. Recognized as a Jiangsu Province AAA-rated Enterprise for Quality Credit, its stringent manufacturing processes ensure consistently high product quality.
In terms of technological innovation, multiple research platforms have been established to develop advanced products and technologies, including high-voltage and extra-high-voltage cables. For green development, the company has been selected as a national-level green factory, achieving 100% green raw material sourcing and industry-leading energy efficiency. These accomplishments have solidified its position as an industry benchmark.

Establishing a Comprehensive,
Multi-Dimensional Quality Control System
  • 01
    Comprehensiveness and Systematization

    End-to-end process control, from incoming raw material inspection (IQC) to final quality control (FQC), ensures rigorous monitoring and assurance at every stage of manufacturing. This systematic approach facilitates early identification and resolution of issues throughout the product lifecycle, thereby enhancing overall quality.

  • 02
    Prevention and Interception

    Through in-process quality control (IPQC) and real-time monitoring of critical process parameters, deviations during production are prevented, and non-conforming products are promptly intercepted. This proactive approach minimizes waste and rework, ensuring that defective products do not reach the market and enhancing customer satisfaction.

  • 03
    Multi-Tiered Quality Defenses

    The three-tier inspection system — self-inspection, mutual inspection, and specialized inspection — establishes multiple layers of quality defense involving operators, preceding processes, and dedicated quality inspectors. This multi-level inspection mechanism strengthens the reliability of quality control and ensures effective monitoring at every stage.

  • 04
    Customer Trust and Compliance

    Final Quality Control (FQC) guarantees that products fully meet customer requirements and industry standards before dispatch, fostering customer trust and enhancing brand reputation. Compliance is a vital aspect of business operations, ensuring products adhere to all relevant standards and mitigating legal risks and potential financial losses.
