Q: What is the difference between CGO and Hi-B CRGO?
A: Conventional CGO is cost-effective for common distribution transformers. Hi-B high-induction CRGO has lower core loss, lower noise, for large grid and energy-saving premium transformers.
Q: What thickness of CRGO do you supply?
A: Full thickness range: 0.18mm, 0.23mm, 0.27mm, 0.30mm, 0.35mm, covering high-frequency and power-frequency transformer demands.
Q: Can you provide tension coating for transformer use?
A: Yes. We supply standard insulation coating and professional stress tension coating, effectively reducing transformer operating hum noise.
Q: What documents can be provided for project customs clearance?
A: Mill Test Certificate, SGS magnetic inspection report, packing list, commercial invoice and original export declaration documents are provided.
Q: What payment and cooperation terms are available?
A: T/T, Irrevocable L/C at sight are acceptable. Long-term transformer factory clients can apply for negotiable credit payment terms.
