GCK Low voltage withdrawable switchgear is widely used in power generating plant, metallurgy rolled steel, textile, seaport and dock, high building, hotel and etc, operating in the system of AC 3-phase 4-wire or 5-wire, voltage 380V, 660V, frequency 50Hz, rated current 5000A and below, to distribute electricity and centrally control motors.
GCK switchgears had been tested completely, awarded CCC certificate, a super low voltage switchgear to be assembled. Comply with GB7251.1-2005 Low voltage switchgear and controlgear, IEC60439-1 Low voltage switchgear and controlgear standard.
Normal service conditions
■ When the ambient air temperature is -15℃-+40℃, the mean value is no greater than+35℃ with in 24 hours.
Note: if the upper limit is higher than +40℃ or lower limit lower than -5℃ in work, discussions shall be made between the user and the manufacturer.
■ Altitude: not higher than 2000m for the installation site.
■ Relative humidity not exceed 50% at the max temperature of +40℃, higher relative humidity is allowable under lower temperature. For example, RH could be 90% at +20℃, while special measures shall be taken for the condensation occasionally produced due to temperature change.
■ Storage ambient temperature: -25℃~+55℃; No greater than+70℃ with in 24 hours.
■ The ambient air is not significantly polluted by dust, smoke, corrosive and/or flammable gases, vapours or salt.
Notes: If the operating conditions exceed the normal conditions, please contact our technical department.
