❓ Frequently Asked Questions

What does the semi-insulated design mean for this product?

The semi-insulated design means that the busbars and certain high-voltage live components are encased in insulating materials. This approach effectively reduces phase-to-phase and ground clearance distances, allowing the overall cabinet structure to be more compact while maintaining electrical safety standards.

What switch unit configurations are available?

The core switch unit can be flexibly configured in three ways: as a load switch, as a load switch-fuse combination, or as a vacuum circuit breaker. This flexibility allows the product to be adapted for a wide range of power distribution and protection requirements.

What are the "five-prevention" interlock functions?

The "five-prevention" interlock functions are a comprehensive set of safety mechanisms designed to prevent common misoperations in high-voltage switchgear. They typically include preventing: closing onto a live busbar, disconnecting under load, grounding while energized, entering a live compartment, and operating in an incorrect sequence — all of which help ensure safe and reliable operation.

What is the rated current switching capacity of this product?

The standard configuration supports a rated current switching capacity of 630A, along with transfer current closing capability. This makes it suitable for medium-voltage distribution networks that require dependable load management and switching operations.

What is the short-circuit withstand current rating?

This product is rated to withstand a short-circuit current of 20kA for a duration of 3 seconds (20kA/3s). This high withstand capability ensures the equipment can endure fault conditions without structural damage, providing strong protection for both the switchgear and the connected network.

Why is high-quality steel used for the cabinet construction?

High-quality steel plates are used to ensure the cabinet's mechanical strength, durability, and resistance to deformation under operational stress. This choice of material contributes to the overall robustness and long service life of the product, making it well-suited for industrial and utility-grade power distribution environments.
