SHEMAR POWER is recognized as one of the world’s leading suppliers of composite insulation products for high-voltage power transmission systems.
As global demand for reliable power infrastructure continues to grow, manufacturers of composite bushings and insulation systems are placing increasing emphasis on gas handling accuracy, environmental safety, and production efficiency.
Shanghai KSTONE has maintained long-term cooperation with SHEMAR POWER, providing a wide range of SF₆ and environmentally friendly gas handling equipment for production, maintenance, and testing applications.
Shanghai KSTONE has supplied multiple types of gas handling and testing equipment for SHEMAR POWER’s operations.
The delivered systems include:
- High-sensitivity quantitative SF₆ leak detector LF-1D+
- Portable SF₆ quantitative leak detector LF-301
- SF₆ gas recovery systems
- Vacuum pumping units
- Complete C4F7N gas detection and handling systems
These systems are widely used for:
- Gas leakage testing
- Vacuum processing
- Gas filling and recovery
- Gas purity management
- Environmentally friendly gas applications
With increasing global attention on carbon reduction and environmentally friendly power technologies, C4F7N-based gas systems are becoming an important development direction for the electrical industry.
Shanghai KSTONE has also supplied complete C4F7N gas handling solutions for SHEMAR POWER, including:
- Gas detection systems
- Gas handling equipment
- Recovery and purification systems
- Mixed-gas processing devices
These systems support the transition toward next-generation environmentally friendly insulating gas technologies for medium- and high-voltage applications.
In recent months, Shanghai KSTONE has continued supplying equipment for SHEMAR POWER’s manufacturing operations in Vietnam.
The delivered systems support local production and gas handling requirements for high-voltage electrical insulation products, further strengthening cooperation between the two companies in international markets.
As global power equipment manufacturing expands across Southeast Asia and other emerging markets, demand for reliable SF₆ and environmentally friendly gas handling solutions is expected to continue growing.
Recently, representatives from SHEMAR POWER visited Shanghai KSTONE for factory inspection, technical evaluation, and equipment acceptance activities related to SF₆ and C4F7N gas handling systems.
The visit included:
- Equipment performance verification
- Technical communication
- Production inspection
- System testing and operational demonstrations
Such cooperation reflects the long-term technical collaboration between both companies in high-voltage gas handling applications.
Through continuous cooperation in SF₆ and environmentally friendly gas technologies, Shanghai KSTONE remains committed to supporting global power equipment manufacturers with reliable gas detection, recovery, vacuum, and gas handling solutions.
The company continues to expand its capabilities in both traditional SF₆ applications and next-generation environmentally friendly gas technologies such as C4F7N.
