1.2 kV 1200A Tri-Clamp Secondary Bushing
The 1.2 kV 1200A Tri-Clamp Secondary Bushing is engineered to provide a secure and efficient interface between transformer secondary windings and external low-voltage bus systems. Its reinforced tri-clamp structure ensures strong mechanical pressure at the contact point, helping to maintain consistent electrical performance even under high thermal and mechanical stress. Compared with standard secondary bushings, the 1200A version is optimized for higher load capacity, improved heat dissipation, and enhanced contact stability in continuous operation environments. Current ratings and characteristics are in accordance with IEEE Standard C57.12.
Key Features
These secondary bushings are molded with HTN high temperature nylon. The HTN high reliability fulfills the required application needs for temperature stability, strength, toughness, low moisture absorption and retention of viable mechanical and electrical properties in humid high-temperature environments. The gasket surfaces provide controlled compression and containment of the highly resilient ACM rubber gasket.
Typical Applications
The 1.2 kV 1200A Tri-Clamp Secondary Bushing is widely applied in high-power low-voltage systems, including:
- Large-capacity pad-mounted transformers
- Industrial power distribution transformers
- Data center power supply systems
- Heavy-duty manufacturing facilities
- Utility low-voltage distribution networks
- Renewable energy power conversion stations
- High-load electrical substations
It is especially suitable for systems requiring stable high-current secondary output with minimal voltage loss.
