CT□- type spring operated mechanismDetailed product description：

Overview
The CT □ - type spring lifting mechanism is an improved mechanism based on the Japanese Mitsubishi VPR indoor high-voltage vacuum circuit breaker. It is a newly designed simplified and integrated spring operating mechanism to achieve miniaturization, high reliability, and maintenance free of the circuit breaker. The structure of the mechanism is more reasonable, the number of components is reduced, and the action is more reliable. All grinding parts are lubricated with long-term grease or oil-free bearings, greatly improving the reliability and service life of the operating mechanism.
This institution is used for indoor high-voltage vacuum circuit breakers ranging from 10KV to 35KV, and its closing power is equivalent to other types of vacuum circuit breakers. Its performance meets the requirements of GG1984 "AC High Voltage Circuit Breakers" and this product's "Technical Conditions", and all indicators meet or exceed the "ICP" standard, and it has fully passed the type test accepted in the high-voltage quality supervision inspection.

Main technical parameters
