Your Solution for Data Centers

Data centers face constantly changing rack densities, strict uptime and safety requirements, and tight white-space constraints that make traditional cable runs hard to manage. Bundled cables can impede airflow and complicate aisle layouts with every change presents challenges delays. Teams must route power cleanly above live environments without disrupting operations. 

That's why LS Busway designed Data-way (UL). Overhead busway turns power distribution into a modular system that supports units placed where support is needed fast with predictable changes while keeping floors clear and airflow unobstructed. 

Engineered for the demands of data centers, Data-way (UL) is tailored for fast installation features, and scalable design. Data-way (UL) is ideal for today’s high-density, mission-critical environments where power reliability and flexibility are essential.
