12kV Indoor FZRN25 Vacuum Load Switch

The FZRN25 indoor vacuum load switch is a vacuum arc-extinguishing switchgear specifically developed for 12kV power distribution systems. It is compatible with ring main units, prefabricated substations, switching stations, and other complete power distribution equipment. The product uses vacuum arc-extinguishing technology to replace the traditional compressed air arc-extinguishing structure, providing superior protection and short-circuit breaking capabilities. The device features a compact overall structure, small size, and modular integrated design, making installation and commissioning convenient. Its performance surpasses that of traditional load switches, making it a core switchgear for safe, stable, and efficient 12kV medium-voltage power distribution systems.Multiple current schemes are available.

Product Details
Feature
  • Excellent Functionality: Utilizes a vacuum arc-extinguishing chamber instead of traditional compressed air arc extinguishing, resulting in faster arc extinguishing and stronger insulation performance.
  • Mechanical Safety Interlocking: Equipped with a professional mechanical interlocking device, working in conjunction with fuses to achieve precise overload and short-circuit protection.
  • Wide Adaptability: Compatible with mainstream 12kV complete sets of equipment such as 12kV ring main units, prefabricated substations, and distribution switchgear.
  • Long Mechanical Life: Mechanical life far exceeds that of traditional load switches; resistant to aging and damp heat, ensuring long-term continuous and stable operation.
  • Low Maintenance Costs: Features a visual structure for quick fault diagnosis; modular design simplifies maintenance.
