ANSI Double Porcelain Bushings for Low-Voltage Transformers: A Reliable Insulation Barrier for Low-Voltage Distribution

ANSI double porcelain bushings for low-voltage transformers serve as core electrical components compliant with American National Standards. They act as critical junctions connecting the internal low-voltage windings of transformers to external circuits. Featuring a unique dual-porcelain structure design and exceptional insulation performance, these bushings establish a robust defense for the safe and stable operation of low-voltage distribution systems. Their main body comprises an outer porcelain body, inner porcelain body, conductive rod, and sealing assembly. The synergistic dual-porcelain design significantly increases the creepage distance and enhances resistance to pollution flashover, adapting to diverse operating conditions from standard clean environments to moderately polluted areas. Furthermore, the nested fit between the inner and outer porcelain bodies strengthens mechanical support, enabling stable handling of long-term load currents and short-circuit surge currents. The conductive rod is crafted from high-conductivity brass or copper, ensuring efficient, low-loss current transmission. Paired with a multi-layer sealing structure, it effectively blocks external moisture and dust intrusion, safeguarding the cleanliness and sealing integrity of the transformer's internal insulating oil while preventing leakage risks. In practical applications, this bushing is widely compatible with low-voltage transformers ranging from 1.2kV to 30kV, serving core sectors including urban distribution networks, industrial/commercial power distribution, and residential power supply. Its standardized ANSI specification design balances versatility and interchangeability, offering easy installation and low maintenance costs. It simultaneously meets core technical requirements for electrical strength and thermal stability, establishing itself as an indispensable reliability component in low-voltage power systems. This ensures robust safeguards for secure energy transmission and prolonged equipment operation.
