12kV Center Distance 275mm Embedded Pole

This 12kV embedded pole is designed for high-voltage switchgear, transformers, and power systems, excelling in applications that require high voltage withstand and high current capacity. With multiple rated current options (630A, 1250A, and 1600A), it offers robust short-circuit withstand capability, including short-circuit breaking currents of 25kA and 31.5kA. Its short-time withstand current reaches up to 31.5kA, ensuring reliable performance even under extreme conditions.

The product features excellent power frequency withstand voltage (48kV) and lightning impulse withstand voltage (85kV), ensuring stable operation in complex power environments. Made from high-quality copper or aluminum alloy with tin or silver-plated surfaces, it provides excellent conductivity and corrosion resistance. With a mechanical lifespan of up to 10,000 operations, it is ideal for high-frequency operations, significantly enhancing system reliability.

When paired with a compatible vacuum switch, the embedded pole ensures precise control of contact distance and operation speed, enabling fast and efficient electrical connections and operations, meeting the stringent requirements of modern power systems.
