Advantages of New Energy HVDC Part

Highly reliable electrical connection

Advanced brazing technology for hvdc contactor high purity ceramics shell for relay achieves a hermetically tight, permanent connection between the metal and ceramic, maintaining stable electrical and mechanical performance even under high voltage, high current, and harsh environments.

Insulation and heat dissipation

The high-purity ev relay metallized high alumina ceramic shell combines high dielectric strength, volume resistivity, and excellent thermal conductivity, protecting against high-voltage arc breakdown while providing rapid heat dissipation, thus enhancing load capacity and lifespan.

Customized metallization layer

Professional metallization treatment of the metallized alumina-based ceramics for ev dc contactor surface forms a robust, highly conductive layer, providing a perfect interface for brazing. This is the core technology for high-performance ev relay metallized high-alumina ceramic components.

Robust sealed structure

The mechanical strength of the brazed joint is close to that of the ceramic body, with excellent hermetically tightness. It can resist arc impact, mechanical stress, and the intrusion of external impurities, ensuring long-term safe operation of the components.

Manufacturing Process

Metalized Ceramics For Electrical Components

Ceramic preparation

High-purity alumina powder with a purity of over 96% is selected and formed through dry pressing, isostatic pressing, or tape casting, followed by precision sintering to create high-density, high-strength relay alumina ceramic components.

Metallization and brazing

As described above, through multiple precision processes including metallization, nickel plating, assembly, and brazing, a non-removable hvdc contactor high purity ceramics shell for relay is formed.

Post-treatment and electroplating

After brazing, necessary cleaning and grinding are performed. The metal parts can be plated with silver, gold, tin, etc., as required to optimize ev relay metallized high alumina ceramic conductivity, solderability, and corrosion resistance.

Applications of New Energy HVDC Part

Remote renewable integration

Transmitting power from large, geographically distant solar farms and offshore wind parks to load centers efficiently.

Offshore wind evacuation

Connecting large offshore wind farms to the mainland grid using submarine hvdc cables, a major growth area.

Grid interconnection

Linking separate ac grids (even at different frequencies) and enabling intercontinental energy trading for better balancing and resilience, notes this article.

Reinforcing existing grids

Increasing power capacity in congested corridors where new ac lines are difficult to build, often serving as "electricity highways".

Urban infeed

Delivering large amounts of power into dense city centers with minimal right-of-way.

Multi-terminal hvdc systems

Creating flexible dc networks (supergrids) for efficient distribution of renewable energy across regions or continents.
