Feature
1) 3 Phase Pad-mounted Transformer has strong overload capacity. It allows 2 times of overload for 2 hours. It can even be overloaded 1.6 times for 7 hours without affecting the service life of the 3 Phase Pad-mounted Transformer.
2) 3 Phase Pad-mounted Transformer adopts elbow plug connector. It can be very convenient for the connection of high-voltage incoming cables. Used as a load switch in emergencies. It can be plugged and unplugged under power.
3) The 3 Phase Pad-mounted Transformer is protected by double fuses. The plug-in fuse (BAY-o-net) is a dual sensitive fuse (temperature, current) to protect the short-circuit fault that occurs on the secondary side of the 3 Phase Pad-mounted Transformer. The backup current-limiting protection fuse (ELSP) protects the internal faults of the 3 Phase Pad-mounted Transformer and is used to protect the high-voltage side.
4) The 3 Phase Pad-mounted Transformer can use Fr3 vegetable oil or mineral oil. It can be selected according to its situation.
5) 3 Phase Pad-mounted Transformer adopts a fully enclosed structure design. It places windings, iron cores, fuses, and high-voltage load switches in the oil tank.
