Rockwill 69 kV Dead Tank Circuit Breakers have been integral to smart substation upgrades, achieving near-perfect power supply reliability.
Project Overview
Deployed in a 110kV smart substation upgrade at a coastal industrial park in Guangdong Province, our RMR-72.5kV vacuum circuit breaker has delivered 24 months of zero-failure operation under high-salinity, high-humidity conditions and frequent switching demands. Power supply reliability reached 99.99%, providing robust support for the park’s green manufacturing and digital transformation initiatives.
Engineered for Excellence & Durability
Each breaking unit integrates a vacuum interrupter with exceptional insulation recovery performance, ensuring superior interruption of short-circuit and short-line faults. The fully self-powered arc-quenching structure effectively handles multiple lightning strikes and evolving fault currents. Maintenance-free vacuum interrupters eliminate periodic inspections, cutting maintenance man-hours by 70% and significantly optimizing life-cycle costs—perfectly meeting industrial users’ dual demands for high reliability and operational economy.
Driving Infrastructure Forward
As a benchmark in medium-voltage green intelligent equipment, the RMR-72.5kV is widely deployed across coastal industrial zones, data centers, and PV/wind power plants. Its “zero maintenance, high breaking capacity, strong adaptability” profile accelerates low-carbon upgrades of distribution networks. We continue advancing vacuum technology and smart O&M integration to deliver safe, efficient, and sustainable Chinese solutions for global energy transition.
