● Standard scheme of cable inlet & outlet and interconnection cabinet for small current switchgear: W 1100×D 1200×H 2650.
● Standard scheme of coverhead inlet and outlet wire cabinet for small current switchgear: W1100×D(1200+400)×H2650.
●Standard scheme of cable inlet & outlet and interconnection cabinet for heavy current switchgear: W1100×D1200×H2650.
●Standard scheme of overhead inlet & outlet wire cabinet for heavy current switchgear: W1100×D1200+600×H 2650.
Note;The phase-to-phase spacing is 250mm for current switchgear; and the phase-to-phase spacing is 275mm for heavy current switchgear.
1. With good overall strength and good looking, the switchgear cabinet structure can be altered into full modular type.
2.The cabinet has good compatibility with circuit breakers, and the compatible circuit breakers include the following types: ZN28A, ZN28D, AN65,ZN12,Vep and VD4.
3. Reasonable structure: independent circuit breaker compartment, busbar compartment and relay compartment, which are isolated with steel plates.
4. It adopts mechanical "five-prevention" interlocking mechanism with good safety and reliability.
5. The cabinet body can be maintenance at both sides. From the front side of the cabinet, the secondary components of relay compartment can be inspected. Form the back side of the cabinet, the cable terminals and main busbar can be maintained. Generally, the cabinet is not installed against the wall.
6. With good performance-price ratio, it still enjoys a considerable market share at present.
7. According to the requirement, the cabinet can be installed against the wall.
8. The protection class of the enclosure is IP4X.
