Product Features:
·Micro-positive pressure nitrogen or dry air insulation, vacuum interruption; insulation characteristics are unaffected by altitude, moisture, or pollution.
·Modular structure design. The main switch adopts three-position switch-vacuum load switch or three-position switch-vacuum circuit breaker structure.
·Line-side grounding is realized by closing the vacuum arc-extinguishing chamber, with no risk of insulation gas degradation and longer electrical life.
·Rated filling pressure 0.02MPa (relative value, 20°C) gauge pressure. All electrical performance is met at zero gauge pressure under normal conditions.
·Compact structure, flexible solutions, convenient combination, small footprint, and no gas handling required on site.
·Laser welding and helium leak detection ensure the air tightness and long-term weather resistance of the gas tank.
·Silicone rubber plug-in connection structure is adopted to realize plug-in installation of high-voltage components and expansion of the cabinet.
·Can be equipped with intelligent remote control, monitoring units, and integrated digital relays.
