Quick Details
Description
- Place of Origin: Jiangxi, China (Mainland)
- Brand Name: XILING
- Model Number: XL-MNS
- Type: Conventional
- Poles Number: Other
- Certificate: IEC 61641 IEC 60298 IEC439 IEC299
The MNS switchgear is divided into separate equipment, busbar and cable compartments.
The design solutions used clearly decrease the possibility of damages occurring to components inside the switchgear. In the unlikely event of arcing, damage is localized in the compartment where the arc occurred. This allows fast repair and recommissioning of the switchgear.
The basic elements of the MNS frame construction are “C” shaped steel profiles with a 25 mm (=1E) hole pitch according to DIN 43660. The profiles are galvanic protected (Zn or Al/Zn) against corrosion. The assembly is maintenance free.
MNS switchboard enclosure is made of sheet steel protected by galvanic coating and powder coating for maximum durability.
Final construction varies depending upon the required degree of protection (IP) In accordance with the general safety philosophy followed with MNS, each compartment and sub-compartment which requires access for commissioning, operation or maintenance, has its own door.
The MNS main busbar system is arranged in the rear of the switchgear in the busbar compartment. This assures a maximum distance between the busbars and the operator and maintenance staff. Special fastening method guaranties safe connections during the whole life cycle without the need of additional tightening. Main busbars are divided into sections depending on transportation units. Main busbars can be manufactured from aluminium or copper. As option fully insulated solution utilizing heat shrinkable sleeving is available.
Copper or aluminium (optional) distribution busbars run vertically the full height of the cubicle and are used for feeding of outgoing modules. In case of withdrawable module solution distribution busbars are manufactured from silver plated copper and embedded into a multifunction wall. The multifunction wall is a unique MNS design. It constitutes a complete barrier between the main busbars and the equipment compartment. The distribution bars are fully phase segregated and insulated. This design makes it virtually impossible for an arc to pass between distribution bar phases or between main busbars and equipment compartment.
System highlights:
-Maintenance free busbar construction
-Easy switchgear extension
-Main busbar arrangement at the rear thus assuring
-maximum safety to personnel
−effective withstand against highest stresses in case of short circuit
−optimum heat dissipation
−Gas tight seals for connection from the equipment compartment to the main busbars system
−Option for Form 4 separation for both incoming and outgoing assemblies
−Active and passive arc fault prevention tested according to IEC 61641
−Isolating materials are free of CFC and halogen
