Open-close 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 pads to prevent rain from entering. Of course, most so-called waterproof transformers on the market use rubber pads as a means, but there are also limitations in using this means for waterproofing. Because it is impossible to guarantee the water proof of the transformer itself ,our company adopts the technology of transformer forming once, that is, the transformer is directly made into a solid in the mold, and the plastic is wrapped around the whole body without any gap. Meanwhile, waterproof terminals and sheath lines are used in the secondary side leads to ensure that no rain can enter the transformer body. Our company transformer waterproof grade has reached IP67/IP65. This product meets part of the standard GB20840.1.2 .
