● Environmental temperature:(-5~40) °C;
● Environmental humidity: ≤80%
● Altitude:≤1000m
● Installation location: indoor, without metal dust or severe vibration;
● There is no serious pollution in the atmosphere of the installation site, and there is no gas or conductive dust in the medium that can corrode metals and damage insulation.
The transformer mainly consists of a coil and a plastic casing, which is dry insulation.
The primary busbar - cable or busbar - passes through the window opening. The transformer can be clamped onto the busbar by tightening screws or fixed and installed with screws through the mounting plate.
