This state - of - the - art design makes use of advanced epoxy sealing technology. The epoxy resin is precisely applied to create a comprehensive and impermeable seal around the device's internal components. This seal acts as a formidable defense against a multitude of external threats. It effectively keeps out dust, which could otherwise accumulate and cause electrical short - circuits or mechanical malfunctions. Moisture is also blocked, preventing corrosion of sensitive electrical parts that could lead to performance degradation over time.


To further enhance protection, the interior of the device is filled with nitrogen. Nitrogen, an inert gas, replaces the oxygen - containing air within. This is crucial because oxygen can promote oxidation of metal components, especially in the presence of moisture. By eliminating oxygen, the risk of corrosion and subsequent damage to electrical elements is significantly reduced, ensuring stable operation under a wide range of environmental conditions.


The contact within the device is crafted from silver alloy, which offers remarkable anti - adhesion performance. When electrical current flows and the contacts open and close, there is often arcing and heat generation. The unique properties of the silver alloy enable it to resist the tendency to stick together during these processes. This ensures smooth and reliable electrical connections, minimizing power losses and equipment failures.


Due to these combined and highly beneficial features, this technology has become extremely popular and is being more widely used in industrial vehicles. Industrial vehicles operate in tough environments, from construction sites filled with dust to factories with fluctuating humidity levels. This technology's ability to withstand such conditions while maintaining consistent performance makes it an ideal choice for powering and controlling various systems within industrial vehicles, thus enhancing their overall functionality and durability.
