Tank Hole Size: Fits standard 1.44″ (36.5mm) diameter openings.
Voltage Range: 1.2kV up to 5.0kV (75kV BIL).
Configurations: Complete assemblies (includes gaskets, hardware, and connectors) or insulators only.
4. Solving Procurement Pain Points
1. Guaranteed ANSI Interchangeability
We understand that “Standard” must mean standard. Our bushings are designed to meet exact ANSI dimensional requirements, ensuring they fit your existing transformer tanks without costly field modifications.
2. Mechanical Integrity (The “Thread & Seal” Factor)
Hardware: Heavy-duty brass or tin-plated bronze terminals for superior conductivity.
Sealing: High-performance NBR/Cork gaskets provided to ensure a leak-proof seal against transformer oil or SF6 gas.
Porcelain Quality: Non-porous, glazed wet-process porcelain for maximum sheds’ self-cleaning and UV stability.
3. Rigorous Testing & Compliance
Every assembly undergoes:
Dimensional Verification: To ensure 100% fit-rate.
Power Frequency Withstand Test: Validating insulation safety.
Visual Inspection: Zero-tolerance for glaze defects or hair-cracks.
