2,max.temperature +45℃
3,max.average temperature per day +35℃
4,Max.average temperature per year +25℃
5,Min.temperature-30℃(applicable for out-door transformer)
6,min.temperatuer-5℃(applicable for in-door transformer)
7,Relative humidity≤90%
8,Waveform of power supply voltage approximately sino-wave
9,Multi-phase powr supply should be approximately symmetric
Installation Environment
1,Transformer should be installed in dry area without any harmful smoke, gas, erosive
Dust,water steam.smog,and heavy humidity environment.
2,There must be enough place ground the transformer to ensure the repair and
Maintenance.
3,There should be no serious fluctuation at installation site.
Wiring:
1,Input and output power supply cables of transformer should be equipped to meet the relative capacity requirements in accordance
to current.
2,Three-phase power supply cables for both input and output should be according to :A-phase(yellow),B-phase(green) and
C-phase(red).Zero line of power supply should be connected to outer cover of transformer.(If there is outer cover of
transformer,it should be consistent to the symbol of box ).
