The embedded pole is a high-voltage insulation component made of epoxy resin casting, widely used in medium and high-voltage vacuum circuit breakers (VCB), switchgear, and power distribution systems.
It integrates the vacuum interrupter, main conductive circuit, and insulation support into a single unit, enhancing dielectric performance, mechanical strength, and environmental adaptability.
The embedded pole offers advantages such as pollution resistance, moisture resistance, maintenance-free operation, and long service life.
It is ideal for various demanding environments, including substations, industrial enterprises, rail transit, and the new energy sector.
