Main Structural Features
The XGN-40.5 Box-type Fixed AC Metal-clad Switchgear adopts a robust fixed structure. The basic frame is fabricated by welding bent section steel and steel plates, ensuring the cabinet enclosure meets the IP2X protection class.
This switchgear is mainly assembled from a front cabinet and a rear cabinet. Air insulation is primarily used between live parts inside the cabinet. The insulation distance between all live parts, and between live parts and ground, is strictly maintained at not less than 300 mm.
Cabinet Configurations
Front Cabinet: Houses the main busbar & busbar disconnector compartment, circuit breaker compartment, and relay compartment. Relays are installed in the middle of the front face, with 15 sections of auxiliary busbar terminals. An M12 grounding bolt is provided at the bottom for auxiliary circuit grounding.
Rear Cabinet: Connected via bolts, it can be equipped with bypass busbars, disconnectors, voltage transformers, or lightning arresters. The rear door features a double-door structure with a safety interlock linked to the live-line indicator.

Frequently Asked Questions
What is the primary application of the XGN-40.5 switchgear?
It is designed for medium-voltage power distribution systems, specifically rated for 40.5 kV AC applications requiring fixed metal-clad protection.
What are the safety clearance distances within the cabinet?
To ensure high reliability, the insulation distance between all live parts, as well as between live parts and ground, is strictly maintained at no less than 300 mm.
What level of ingress protection does the enclosure provide?
The cabinet enclosure meets the IP2X protection class, providing safety against the ingress of solid foreign objects larger than 12.5 mm.
Are there special requirements for high-altitude installation?
The standard design is suitable for altitudes up to 2500 meters. For installations exceeding this height, specific technical modifications or derating may be required upon consultation.
How is the rear cabinet accessed for maintenance?
The rear cabinet features a double-door structure equipped with a safety interlock. It can only be opened when the live-line indicator confirms there is no voltage present.
What types of components can be integrated into the rear cabinet?
It is highly flexible and can accommodate bypass busbars, disconnectors, voltage transformers, lightning arresters, and cable outgoing line connections.
