Product Description

The 12kV Center Distance 205mm Embedded Pole is a high-performance insulation component designed for medium-voltage switchgear. Utilizing advanced solid-sealing technology, it integrates the vacuum interrupter with epoxy resin through a one-shot molding process, significantly enhancing mechanical strength and environmental resistance. With a rated voltage of 12kV, current capacity up to 1250A, and short-circuit breaking capability of 25kA/31.5kA, this product meets rigorous power system requirements. Key features include ultra-low partial discharge (≤5pC), extended mechanical lifespan (10,000 operations), and a 20-year storage period, ensuring long-term reliability. Compatible vacuum switches are precisely matched, featuring a contact gap of 9±1mm, controllable opening/closing speeds, and contact pressure up to 3200N, which optimize operational stability and arc management. Ideal for grid upgrades, industrial distribution, and renewable energy applications, it delivers superior performance in diverse electrical environments.
