FAQs
What are the core differences between the 36KV VS1 circuit breaker and the 35KV model, and can they be used interchangeably?
The core differences lie in international certification levels, extreme environmental adaptability, and insulation performance, which are not interchangeable. The 36KV model is deeply compatible with international top-level standards and has passed international top-level certification, with better insulation and protection performance. It focuses on high-end foreign-related and extreme environmental scenarios; The 35KV model focuses on domestic high-voltage distribution network backbone and large-scale energy bases, only following domestic standards, and its insulation and protection performance is suitable for conventional high-end scenarios in China. There are significant differences in the rated voltage, insulation level, and structural dimensions between the two, and forced exchange can lead to arc extinguishing failure, equipment burnout, and even distribution network failures.
