This innovative solution incorporates epoxy encapsulation technology, creating a hermetic and resilient barrier. The epoxy material is carefully applied to encapsulate the internal components, acting as a reliable safeguard against the ingress of dust particles, humidity, and corrosive substances. By doing so, it effectively mitigates potential damage from the external environment, thereby enhancing the device's long - term reliability and reducing the likelihood of malfunctions.


Internal nitrogen filling is also an integral part of this design. Nitrogen, being an inert gas, is introduced into the interior of the device. This replaces the oxygen present in the air, effectively curbing the occurrence of oxidation reactions that could otherwise degrade the performance of electrical components over time. The nitrogen - filled environment ensures that the device can maintain consistent operation, even in challenging or variable environmental conditions.


In addition, the use of silver - alloy contacts is a key differentiator. These contacts possess outstanding anti - welding properties. During the switching process of electrical circuits, when arcs are generated and high temperatures are present, the silver - alloy contacts resist the tendency to adhere or weld together. This ensures that electrical connections can be made and broken smoothly, without any disruptions or failures, thus guaranteeing efficient electrical performance.


As a result of these combined features, this technology has found widespread acclaim and extensive application in the industrial vehicle sector. Industrial vehicles operate in diverse and often harsh settings, ranging from dusty construction sites to humid industrial environments. This technology's ability to endure such conditions while providing stable and dependable performance makes it an ideal choice for powering and controlling various systems within industrial vehicles, contributing to their optimal functionality and longevity.
