Can be remotely controlled through a remote power sales system.

The airtight design effectively isolates the influence of the external environment, enabling long-term stable operation in various complex and harsh environments.

Micro-positive pressure design reduces leakage risk, and zero gauge pressure meets all national standard electrical performance requirements (including short-circuit breaking). The metal casing is reliably grounded, ensuring safety and reliability.

Spring energy storage, cam drive, and four-bar linkage mechanism, with a simple structure, stable performance, and long mechanical life.
