11kv switchgear switchgear transformator switchgear
Product Description
Product Description Product Overview Overview
MNS2.0 low-voltage Switchgear (hereinafter referred to as Switchgear) is applicable for an AC 50~60Hz power distribution system with rated working voltage of 690V; used for all low voltage power distribution systems. It is widely applied in various industries including electric system, petrochemical engineering, industrial and mining enterprises, public utilities, municipal engineering, and commercial buildings.
Thus MNS proves to have the approved solution for the following industries:Oil &Gas,on and off shore,Chemical/Petrochemical,Pharmaceutical,Power Stations,Paper,Water treatment,Mining,Steel,Food, Marine as well as for infrastructure requirements: Data centers, Airports,Office buildings, Shopping centers,Hospitals,Rail
Standards:GB7251.12-2013, IEC61439-1/-2
Working and environmental conditions:
MNS2.0 low-voltage switchgear is designed for indoor installations. The protection classes for MNS2.0 can be up to IP54 under other working conditions.
Environmental temperature:
Maximum short-time temperature: +40℃
Maximum 24h average temperature: +35℃
Minimum temperature : -5℃
Aerating under more rigorous conditions.
Working conditions for measuring, metering instruments and protective relays should conform to the specification of the
manufacturers.
The climatic conditions should be relative humidity of ambient environment: 50% at 40℃.
Switchgear installed indoors should have such conditions as comply with requirements of relevant standards. Measures for prevention of condensation such as ventilation or heating should be used for the switchgear where condensation may occur. Altitude: Not more than 2000m. Equipment should be operated at a reduced capacity when the switchgear is installed at an altitude of more than 2000m.
Main features:
Notable system advantages with regard to design aspects:
⚫Optimum protection for personnel and plant
⚫Design verified by testing (type-tested)
⚫High operational reliability and availability
⚫ Earthquake-, vibration- and shock-proof designs are available
⚫ Maintenance-free busbar and frame construction
⚫Simple retrofitting procedures
⚫Compact, space-saving design
