Product overview

Open-close type outdoor waterproof transformer. The biggest feature of this series of transformers is the waterproof function, which can be used outdoors. Its section port is surrounded by rubber pad to prevent rainwater from entering. Of course, most of the transformers on the market are called waterproof by rubber pad, but this method has limitations, Because it is impossible to guarantee the waterproof of the transformer body, our company adopts the one-step molding technology of the transformer, that is, the transformer is directly made into a solid body in the mold, and the plastic body is wrapped without gaps. At the same time, the secondary side lead adopts waterproof terminal and sheath wire to ensure that no rainwater can enter the transformer body, which has been tested by authoritative institutions, Our company transformer waterproof grade reached IP67/IP65. This product complies with standards GB/T20840.1.2, IEC 61869-1 and IEC 61869-2.
