Introdu\u00e7\u00e3o geral<\/strong><\/h2>\n
\n
\n

SN10-10 series 10kV Indoor Less Oil Circuit Breaker is a traditional type medium voltage oil circuit breaker. It takes transformer oil as the arc quenching and insulating medium, with simple mechanical structure, stable breaking performance and high cost performance.
\nThis circuit breaker is mainly designed for 10kV indoor power distribution systems, suitable for frequent closing and opening operation, as well as overload and short-circuit fault protection for transformers, power lines and electrical equipment. It is widely adopted in old substation renovation, industrial plants, mining enterprises and conventional power grid projects.<\/p>\n
