In the market, many electric device wholesale china have three-proof designs, which are moisture-proof design, smoke-proof design and mold-proof design.
electric device wholesale china adopts a sealed or semi-sealed structure so that it can operate normally in adverse environments and the performance of the switch sockets will not be affected. For some components with sealing requirements on the wall switches and sockets, sealing measures have been taken. For non-repairable combination devices, epoxy resin potting has been carried out.
The raw materials and components of household wall switches have very low moisture absorption, and substances that are prone to mold such as cotton, linen and silk should not be used. Its switch panel is made of corrosion-resistant materials. As the switch panel is directly exposed in the air, the outer top is designed to be smooth to avoid corrosion caused by water accumulation.
The electronic devices and other components of electric device wholesale china are over-plated, coated or chemically treated, with a protective film covering the surface to protect the switches from the influence of the surrounding medium. Moreover, its printed circuit boards and component surfaces are coated with three-proof varnish to ensure that there will be no corona and breakdown between the wires. In addition, the inductors and transformers are also sealed and impregnated with varnish to prevent moisture from entering and causing short circuits.
