Junray Electrical is a specialized manufacturer and supplier of instrument transformers in China. Our business encompasses a comprehensive and specialized product portfolio:
For medium-voltage gas-insulated switchgear (GIS), we independently develop and manufacture specialized current and voltage transformers (rated 0.5–35 kV). Utilizing advanced sealing processes and smart sensing technology, these units offer superior insulation and interference resistance, effectively reducing power losses while ensuring stable and safe power transmission. Additionally, our current and voltage transformers designed for pole-mounted switches—featuring integrated primary and secondary systems—deeply incorporate smart monitoring and control technologies to enable real-time monitoring and precise control of power lines, making them ideal for distribution network automation projects.
Regarding current, voltage, and zero-sequence transformers designed for metal-clad switchgear and ring main units (RMU), we meticulously consider the specific operating environments and performance requirements of the equipment. Through optimized structural design and material selection, these transformers deliver excellent overload capacity and sustained accuracy, ensuring stable operation even under extreme conditions.
Junray Electrical’s instrument transformers stand out due to leading-edge technology and exquisite craftsmanship, boasting industry-leading performance specifications. They have been successfully deployed in numerous major power projects—such as urban smart grid upgrades and power infrastructure for industrial parks—where their stable, reliable performance has earned widespread acclaim from users while effectively lowering equipment failure rates and maintenance costs.
