WHAT WE OFFER

Power Equipment Solutions

Saudi Mobile Substation Project

Custom neutral grounding resistor cabinets built for vehicle-mounted substations on Saudi Arabia's national grid, freely switchable between 13.8 kV and 33 kV. A layered compact layout fits the limited truck-mounted space while maintaining high-altitude insulation clearance. Designed, produced and delivered in four months — all five stations energized successfully in July 2025.

US Data Center Power Protection

Six custom neutral grounding resistor cabinets supplied for a major data center project in the United States. They limit single-phase earth-fault current and suppress arcing and resonance overvoltages below 2.5× phase voltage, while delivering clear signals for fast fault isolation — protecting sensitive IT loads and supporting reliable 7×24 operation in line with international electrical safety standards.
