3.Key Features & Advantages

1. Engineered for Durability

  • Corrosion Resistance: Hot-dip galvanized steel components and stainless steel transmission systems prevent rust, even in coastal or high-humidity regions.
  • Low Maintenance: Flexible busbar connections and self-cleaning grading rings reduce wear, while sealed bearings eliminate frequent lubrication.

2. Enhanced Electrical Performance

  • Optimized Contact Design: Externally compressed stainless contact springs ensure stable pressure and minimal arcing.
  • Reduced RF Interference: Integrated shields and grading rings distribute electric fields evenly, improving safety for nearby equipment.

3. Smart Installation & Adaptability

  • Dual-Side Mounting: Install on either side of the base for flexible grid configurations.
  • Modular Design: Pre-assembled kits simplify deployment in remote or complex sites.

4. Built for Extreme Conditions

  • Tested to withstand hurricanes, ice loads, and rapid temperature shifts.

4.Applications

Be used in a wide range of industries.

 

Industrial Plants

Industrial Plants

Eliminate power factor penalties in CNC machines and assembly lines while handling surge currents up to 100x rated capacity.

Solar/Wind Farms

Substation

Stabilizes substation voltage against harmonics and intermittent generation from renewable inverters.
