Product Details

This product features a semi-insulated design, with busbars and certain high-voltage live components encased in insulating materials to effectively reduce phase-to-phase and ground distances, resulting in a compact structure. The cabinet is typically constructed from high-quality steel plates, ensuring robustness and reliability. The core switch unit can be flexibly configured with load switches, load switch-fuse combinations, or vacuum circuit breakers, equipped with comprehensive "five-prevention" interlock functions to ensure operational safety. Standard configurations support rated current switching of 630A and transfer current closing, with short-circuit withstand current reaching 20kA/3s.

❓ Frequently Asked Questions
Q
What does the semi-insulated design mean for this switchgear?
The semi-insulated design means that the busbars and key high-voltage live components are encased in insulating materials. This effectively reduces the required phase-to-phase and ground clearance distances, allowing the overall cabinet to be more compact without compromising safety or performance.
Q
What switch unit options are available for this product?
The core switch unit can be flexibly configured with three options: a standard load switch, a load switch-fuse combination, or a vacuum circuit breaker. This flexibility allows the product to be tailored to specific application requirements and protection needs.
Q
What is the "five-prevention" interlock function?
The "five-prevention" interlock is a comprehensive safety mechanism designed to prevent five common types of electrical misoperation: closing a breaker under load, pulling out or inserting a live plug-in unit, closing an earthing switch while live, operating a disconnector under load, and entering a live compartment. These interlocks significantly enhance operational safety.
Q
What is the short-circuit withstand current rating of this switchgear?
This product is rated for a short-circuit withstand current of 20kA for a duration of 3 seconds (20kA/3s). This ensures the equipment can safely handle fault conditions without structural damage, making it suitable for medium-voltage distribution networks.
Q
What rated current does this switchgear support for switching operations?
The standard configuration supports rated current switching of up to 630A, along with transfer current closing capability. This makes it well-suited for ring main unit (RMU) applications and medium-voltage distribution systems requiring reliable load switching.
Q
Why is high-quality steel used for the cabinet construction?
High-quality steel plates are selected for the cabinet to ensure mechanical robustness, long-term structural integrity, and resistance to environmental stresses such as corrosion and impact. This contributes to the overall reliability and extended service life of the switchgear in both indoor and outdoor installations.
