Entity Information: A national-level chemical industrial park in Hebei, covering an area of 12.8 km² with 56 fine chemical and petrochemical enterprises. The site is constantly affected by acid-base mist, high humidity and heavy dust. The low-voltage power distribution system adopts SIVACON 8PT538 Low Voltage Withdrawable Switchgear Accessories and complete Siemens 8PT cabinets. In April 2025, the park completed the overall lock upgrade. Traditional rust-prone iron locks were replaced in batches with Zinc alloy door lock for SIVACON 8PT cabinet and SIVACON 8PT538 power distribution cabinet door lock supplied by Ningbo Richge, covering 420 sets of 8PT switchgears in 9 production workshops.
User Profile & Professional Background: Mr. Zhang, 43 years old, Senior Electrical Maintenance Engineer of the industrial park, certified National Registered Electrical Engineer with 19 years of experience in industrial electrical operation and management. He is in charge of low-voltage distribution system renovation, equipment inspection and safety control, and specializes in selection and matching of SIVACON Low Voltage Withdrawable Switchgear Accessories in corrosive environments.
User Experience & Verified Data “Chemical workshops face severe corrosion. Traditional iron locks get rusty and stuck within half a year, leading to loose cabinet doors, delayed maintenance and serious electrical hazards.” Mr. Zhang commented. “After installing Ningbo Richge Siemens 8PT trapped-key interlock door lock and anti-corrosion zinc alloy locks, all locks have operated continuously for 12 months with zero rust, zero jamming and zero loose doors. The multi-point locking structure effectively prevents illegal access and vandalism. The annual replacement rate of lock accessories is reduced by 92%, and daily inspection efficiency increases by 58%. The products match perfectly with original SIVACON 8PT switchgear rotating handle spring lock and 8PT538 Sivacon Low Voltage Switchgear Door Hinge without secondary drilling or modification. Ningbo Richge has been designated as our long-term supplier for High-security door lock for Siemens 8PT switchgear and full set of 8PT cabinet accessories.”
Entity Information: An auto parts intelligent manufacturing factory in Zhejiang, equipped with 12 automated production lines with an annual output of 3.8 million auto parts. The power distribution room is fully fitted with Siemens SIVACON 8PT withdrawable switchgears. Due to frequent equipment operation and inspection, high standards are required for lock safety and operability. In June 2025, the factory completed full lock renewal and adopted Siemens 8PT withdrawable cabinet door lock accessory from Ningbo Richge to solve the problems of messy key management and insufficient access control.
User Profile & Professional Background: Mr. Liu, 36 years old, Electrical Equipment Supervisor of the factory, with 13 years of experience in electrical management for automated production lines. He focuses on safety standardization and equipment upgrading, and is familiar with the application and maintenance optimization of SIVACON Low Voltage Withdrawable Switchgear Accessories in intelligent manufacturing scenarios.
