■Product Features
Through the following safety measures, we can provide special safety guarantees for users:
Integrated Three-Position Load Switch: The circuit breaker uses a load switch to replace the isolating switch, making it safer and more reliable. The primary side fully enclosed design provides protection against accidental contact, meeting the five-prevention requirements. The mechanical interlock with live display can provide reliable indication of live circuits for incoming and outgoing lines.
Fully Enclosed Design: All 10kV switches and busbars are sealed in a gas chamber made of 3mm stainless steel plates.
Silicone Rubber Cable Plug: Achieves full insulation and sealing of the cable head, making it unaffected by dust, moisture, or small animals.
Spring Energy Storage Operating Mechanism: The operating mechanism is unaffected by the external environment. It features manual or electric operation, and a simulated wiring diagram on the panel provides switch position indication. The cabinet body is made of galvanized steel plate with surface electrostatic spraying, enhancing corrosion resistance. A pressure gauge monitors the SF6 gas pressure inside the box to ensure safety.
