CT10,CT10A Spring operated mechanismDetailed product description：

Overview of CT10 and CT10A Spring Operating Mechanisms

The new CT10 spring operating mechanism can be used to operate SN-35 type I and II indoor high-voltage low oil circuit breakers and SF6-35 indoor high-voltage circuit breakers.
The new CT10A spring operated mechanism can be used to operate ZN23-35 indoor high-voltage vacuum circuit breakers. Its performance meets the requirements of "GB1984-89" "AC High Voltage Circuit Breakers" and the "Technical Conditions" of this product, and its main indicators meet or exceed the "IEC" standard.
The new CT10/CT10A spring operating mechanism is an improved production based on the original CT10/CT10A. Its stability far exceeds that of the original product, with a mechanical lifespan of no less than 6000 times, which is three times stronger than the original product.

Main technical parameters
The energy storage motor adopts HD2 type, and its technical parameters are shown in Table 1.
