Electro-Vacuum Device R&D Capabilities
Wanping develops vacuum relays, vacuum capacitors, switch tubes and vacuum interrupters from confirmed electrical parameters, equipment interfaces and operating conditions.
Our engineers convert voltage, current, contact configuration, coil voltage, capacitance range, switching duty and installation limits into the internal structure of the product. The development work covers contacts, electrodes, insulation layout, coils, bellows, terminals and ceramic-to-metal sealed assemblies.
Engineering Capabilities
Electrical and Structural Design
Voltage requirements define the insulation layout and spacing between conductive components. Switching and carry-current requirements define the contact system, conductive path and terminal connection. Coil voltage defines the electromagnetic structure of a vacuum relay, while capacitance range defines the electrode relationship and adjustment structure of a vacuum capacitor.
Installation and Interface Design
Engineers define the mounting dimensions, terminal positions, connection methods, enclosure shape and mechanism interface according to the available installation space.When the external dimensions must remain unchanged, the internal contact, coil, electrode, insulation or moving structure is redesigned inside the existing installation boundary.
Design for Vacuum-Sealed Constructio
The operating components of vacuum relays, capacitors and switch tubes are enclosed inside sealed ceramic-and-metal structures.Contact alignment, electrode spacing, bellows travel and internal terminal connections are finalized before vacuum processing. The engineering design therefore matches both the required electrical performance and the actual assembly and sealing conditions used in production.

Replacement and Equipment Upgrade Development
Discontinued-Model Replacement
Wanping develops replacement electro-vacuum devices for equipment that must retain its original mounting position, terminal layout and connection method.
The existing product, drawing or installation record establishes the fixed external conditions. Engineers then redesign the internal contact system, coil, electrode structure, insulation layout or moving assembly according to the confirmed electrical requirements.
Performance Upgrades Within Existing Equipment
A good foreign trade website requires a clean layout and fast loading speed to enhance user experience. Search Engine Optimization (SEO) is crucial for improving the website's visibility internationally, allowing more potential customers to find the business.Security is also essential, with features like SSL encryption and reliable payment gateways to protect users' sensitive information.
Additionally, many foreign trade websites integrate social media marketing tools to drive traffic and expand brand awareness through social platforms. To cater to global audiences, these websites should also support mobile access, ensuring customers can browse and purchase seamlessly, no matter where they are.Foreign trade websites have become an effective tool for businesses to expand into international markets, playing a vital role in the global economy.
Prototype Verification and Design Revision
Prototype development confirms whether the proposed structure meets the defined electrical and installation requirements.
The first sample is checked against the confirmed drawing, dimensions, terminal layout and equipment interface. Its operating result is then compared with the required voltage, current, capacitance, contact movement or switching function.
When the result differs from the confirmed requirement, the related internal structure is revised. The drawing, specification and prototype version are updated together until the product definition is finalized.
