Product Description
The Twenty Four Circuit Repeatable Grounding Box is the ultimate ultra-high density, modular grounding solution designed for the world's most challenging large-scale grounding applications, including mega data centers, rail transit hubs, ultra-high voltage converter stations, and vast industrial campuses. This product integrates twenty-four electrically isolated grounding circuits into a compact, weatherproof enclosure, providing independent, testable, and maintainable grounding connections for up to twenty-four equipment or grounding branches. Supporting over 5,000 test and retightening cycles without wire disconnection, it dramatically enhances maintenance efficiency. Its modular, multi-layer, thickened copper busbar design with individual segments for each circuit eliminates interference and circulating currents, maintaining stable grounding resistance of ≤0.1Ω per circuit. The IP65-rated enclosure and ultra-compact footprint reduce panel space by approximately 60% compared to traditional discrete terminals. With scalable architecture supporting expansion up to 32 circuits, it is the definitive solution for engineers and specifiers managing extreme-scale grounding systems where reliability, maintainability, space efficiency, and future growth are critical.
Key Features
1.Maximum Space Optimization: By consolidating 24 isolated circuits into a specialized multi-layer footprint, it saves approximately 60% of vertical and horizontal panel space compared to conventional single-terminal block setups.
2.Unparalleled Fault Surge Rating: Boasts a maximum short-time withstand current rating of 25kA / 1s, providing top-tier resilience against catastrophic lightning strikes and massive short-circuit anomalies without hardware degradation.
3.75% Field Labor Savings: The wire-disconnection-free testing architecture reduces long-term operational maintenance labor costs by up to 75% over the equipment's lifespan.
4.Harshest Environment Defense: Engineered with heavily thickened tin-plated copper and premium PA66 housing components, the entire module resists severe environmental degradation, surviving a ≥144-hour rigorous salt spray protocol and heavy UV exposure within a -40°C to +105°C operating window.
