定义
Insulating supports are critical components in bus bar assemblies designed to maintain precise spacing and alignment between conductive bus bars while ensuring complete electrical isolation from grounded structures. These components prevent short circuits, reduce electromagnetic interference, and enhance system safety by withstanding high voltage stresses and mechanical loads in industrial electrical installations.
工作原理
Insulating supports function by utilizing dielectric materials with high electrical resistance to create physical barriers between conductive bus bars and grounded metal frames. They maintain predetermined clearances as per electrical safety standards, preventing current leakage and arc flash incidents while supporting the weight and thermal expansion of bus bars during operation.
