This series of ANSI 5KV Low Voltage Bushings is specifically designed for oil-immersed distribution transformers. Whether you are upgrading existing grid infrastructure or manufacturing new units, our bushings provide the critical interface between the transformer’s internal windings and the external electrical network.
Technical Specifications (Engineered for Excellence)
Voltage Class: 5KV (Low Voltage side)
Current Range: 630A, 1000A, 1200A, 2000A, 3150A, 4000A.
Insulation Material: High-grade electrical porcelain (Glazed for self-cleaning and weather resistance).
Creepage Distance: 137.4mm (Optimized for 5KV class safety margins).
Terminal Design: Flat Spade (NEMA standard) with multiple hole configurations ($n-\phi d$) to accommodate various cable lugs and busbar sizes.
Sealing Integrity: Equipped with high-temperature resistant gaskets and aluminum clamps to ensure zero oil leakage under thermal cycling.
Key Advantages for Engineers
High Conductivity: We use >99.9% pure E-Cu copper for the conductive stud to minimize heat rise ($I^2R$ losses).
Standard Compliance: Fully compliant with ANSI/IEEE C57.19.01 dimensional and performance requirements.
Durability: The hot-dip galvanized or tin-plated terminal options prevent oxidation in corrosive industrial or coastal atmospheres.
Easy Installation: Standardized tank opening dimensions ($\phi 150mm$ bolt circle) ensure drop-in compatibility with most North American style transformer tanks.
