Structure Introduction
The circuit breaker is a three-phase common box oil immersed mechanism, using plug-in copper tungsten contacts (one piece for Type I static contacts and two pieces for Type II static contacts). The box is equipped with an overcurrent release and a delay device, which can automatically release when the network fails. Oil also serves as an arc extinguishing insulation medium. The manual operating mechanism is installed at the front end of the box and integrated with the switch. The wire passes through the porcelain sleeve fixed on both sides of the box cover and is led out.
DW10-10 I-G type adopts anti type porcelain sleeve and increases the external insulation distance; The box cover and the box body are fully enclosed and connected; The tripping current can be adjusted inside the mechanism cover without opening the box.

The DW13-35 high-voltage multi oil circuit breaker complies with national standards and is used for the protection of 35KV power systems Interlocking between control and system Circuit breakers are divided into two types: those without parallel resistors and those with parallel resistors, both of which have the same technical parameters and basic skills. Circuit breakers with parallel resistors also have reliable performance in meeting no-load long lines. Users must meet the requirements of no-load long lines. Circuit breakers can be used in heavily polluted areas and high-altitude areas

1. There are differences between the rated voltage regulations of IEC standards and national standards. When providing products according to the IE56 standard, the rated voltage and maximum operating voltage are taken from the data in parentheses.
2. The actual short-term power frequency durability of the circuit breaker is higher than the standard specified 80KV, and the factory designs and tests it according to 95KV.
3. The fully open break time is the measured data after the short-circuit break test.
