Description
DW13-35 series high-voltage multi-oil circuit breaker is a three-phase ac 50Hz outdoor high-voltage electrical equipment, suitable for the protection, control and inter-system communication of the main 35kV transmission and distribution system. Each type of product is divided into two types of circuit breakers without parallel resistance and with parallel resistance respectively, both of which have the same parameters and performance. The circuit breaker with parallel resistance also has the reliable performance of fitting the no-load long line, but the cost is higher, it is used in the place where the no-load long line fitting must be carried out.
