Vacuum Box Ammonia Leak Detection System for the Power Industry – Covering Multiple Scenarios, Solving Sealing Pain Points in the Power and Other Industries

This year’s EP Shanghai exhibition focused on power equipment, energy storage, and electrical materials. Boway Optoelectronics showcased its helium leak detection solutions for these core applications, including:
Power Industry Vacuum Chamber Helium Leak Detection System
This system performs dry leak detection on SF6 switchgear/gas-filled switchgear/ring mains units. It uses an in-chamber helium filling and testing method, effectively controlling the pressure difference between the inside and outside of the workpiece to prevent abnormal deformation. The simultaneous use of pressure sensors and vacuum gauges significantly improves the safety factor.
Circuit Breaker and Vacuum Interruptor Sealing Test
This system provides vacuum leakage monitoring and structural sealing leak detection solutions, adaptable to different specifications and cavity structures.
Transformer and Power Electronic Module Sealing Test
Suitable for sealing safety testing of oil-filled equipment and power electronic cooling modules.
Energy Storage System (Cell/Module/Chassis) Helium Leak Detection Solution
This system meets the increased sealing requirements of energy storage equipment, enhancing the system’s protection level capabilities.
Customized Leak Detection Systems for Large and Irregularly Shaped Power Equipment
We provide system-level manufacturing capabilities for non-standard automated helium detection lines, vacuum chamber solutions, and composite testing platforms for equipment with specific structures.
At this exhibition, many power equipment manufacturers came to inquire about solutions based on their actual operating conditions and project needs. The helium testing solutions discussed on-site covered multiple stages from raw materials to final complete equipment sets, demonstrating strong demand scalability. Boway Optoelectronics will provide multi-scenario, multi-product, and multi-dimensional solutions for the power industry.

The exhibition may end, but the story continues – Bowei Optoelectronics’ future plans

Following the successful conclusion of this exhibition, Boway will continue to focus its efforts on the following areas:
- Continuing to promote the localization and upgrading of core technologies for helium mass spectrometer leak detectors;
- Building complete automated helium detection production line solutions;
- Developing multi-scenario, multi-product solutions for industries such as power and energy storage;
- Exploring overseas market cooperation and exhibition strategies.
The three-day exhibition has successfully concluded, but industry exchange will continue. In the future, Bowei Optoelectronics will continue to uphold the principles of “professionalism, innovation, and reliability,” providing high-standard sealing testing solutions for the power and energy storage industries, and driving the upgrading of the energy industry with domestically developed technology.
