Changyun Technology Earns ISO 50001 Energy Management System Certification

Company Aligns Its Energy Management Practices with International Standards

ZHENGZHOU, China, July 18, 2026 — Zhengzhou Zhishi Changyun Technology Co., Ltd. (“Changyun Technology”) was awarded Energy Management System certification by Beijing Cotecna Kaixin Certification Co., Ltd. on July 13, 2026.

The certification marks a significant advancement in the systematic and standardized management of energy use across the company’s operations and demonstrates that its energy management practices are aligned with internationally recognized standards.

Aligning with International Standards to Establish a Refined Energy Management System

The certification was issued in accordance with GB/T 23331-2020/ISO 50001:2018, Energy management systems — Requirements with guidance for use.

The certified scope covers energy management activities throughout the manufacturing process for mechanical equipment, including Fiber Optic Cable Pullers, Cable Feeders, and Cable Pulling Winches. The certificate is valid through 2029.

ISO 50001 is an internationally recognized standard for energy management. Rather than representing a general commitment to energy conservation, it provides organizations with a structured management framework based on the Plan-Do-Check-Act (PDCA) cycle.

Achieving this certification demonstrates that Changyun Technology has established a comprehensive system for monitoring energy procurement, use, and recovery across its operations. The system enables the company to identify inefficient energy use within its production processes and improve overall energy performance by optimizing manufacturing procedures and phasing out energy-intensive equipment.

These measures not only help reduce operating costs but also establish a stronger data foundation for the company’s future participation in green electricity trading and carbon footprint accounting.
