The necessity of using soft copper strips to connect dry-type transformers to the busbars on the top of the cabinet
Thread Content
I. Is there a regulation requiring the use of soft connections? II. What capacity dry-type transformers require flexible connections?
1. The standards do not require that dry-type transformers and the busbars on top of the cabinet be connected using soft copper bars, but their use is recommended to accommodate thermal expansion and contraction as well as to reduce vibration transmission. II. Generally, for dry-type transformers with larger capacities or those requiring stringent installation conditions, it is recommended to use flexible connections. There is no clear limit on the specific capacity; it needs to be determined based on actual conditions and design requirements. .
