Product overview

Outdoor waterproof current transformer. The biggest feature of this series of transformers is the waterproof function, which can be used outdoors. Its cut-off port is surrounded by rubber pads to prevent rainwater from entering. Of course, most of the so-called waterproof transformers in the market use rubber pads, but there are also limitations in using this method for waterproof, 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.
