Porcelain Transformer Bushing Solutions
DIN / ANSI / BS Standard Insulation Solutions β High mechanical strength, superior insulation performance, IEC compliant production for global power infrastructure.
Precision Engineered Porcelain Bushings
Porcelain transformer bushings provide safe electrical insulation and mechanical support for transformer terminals. They are widely used in distribution and power transformers worldwide. ASIAPOWER manufactures bushings compliant with international standards including DIN, ANSI, and BS types, ensuring reliable performance in extreme environments.
Technical Superiority
Our bushings are manufactured using high-grade alumina porcelain, assembled with precision copper or aluminum conductors. Each unit undergoes partial discharge test, power frequency withstand test, and leakage measurement per IEC 60137 and IEEE C57.19.01.
Global Certifications
ISO 9001:2015 certified facility. Routine tests witnessed by third-party inspectors, compliant with CSA, KEMA, and CE requirements. ASIAPOWER supports global OEMs and grid operators.
Key Features & Engineering Advantages
β‘ High Mechanical Strength
Designed to withstand cantilever loads up to 12kN (depending on voltage class), certified by finite element analysis (FEA).
π¬ Excellent Insulation Performance
