Busway electrical insulation materials

The future of AI data centers relies on innovative power distribution. Overhead busways offer a dynamic solution, providing the agility needed to keep pace with technological advancements.


The key to their success? Advanced electrical insulation techniques for metal busbars, creating a robust, safe, and adaptable power distribution system.
This insulation not only protects against electrical faults but also empowers easy device management and scalable power distribution. With the right insulation, data centers can seamlessly add or reconfigure servers without disruptions, specialized tools, or expert intervention.

The industry is now exploring alternative insulation materials to meet the unique challenges of AI power needs, including high power densities and voltage levels up to 800V DC. These materials will help enable efficient busway designs, ensuring AI data centers remain at the forefront of technological innovation.

AI industry requirements for busway electrical insulation

SAFETY: Flame resistance as per UL 94 V-0 standard
RELIABILITY: Dielectric strength to avoid breakdown at higher voltages 
SCALABILITY: Ease of extrusion of longer parts (3m or more)

Comparison of busway insulation material properties

Why not choose the historically utilized GF PA66 for today's AI busway insulation?
  • High moisture absorption. Polyamide acts like a sponge, soaking up ambient moisture that can degrade its dielectric performance and lead to warpage.
  • Dimensional instability. For consistent performance, busway insulation profiles must be straight and uniform. PA66 is prone to in-mold shrinkage and post-mold warpage that can skew part geometries and generate excessive scrap.
  • Extra weight. Glass fiber reinforcement used in PA66 to enhance stiffness adds weight and bulk to busway insulation profiles.
Gain long-term durability with NORYL resins
NORYL resins (PPE) can withstand high heat, humid conditions generated by extreme AI power densities and rapid load fluctuations. NORYL resins exhibit 97% less moisture absorption vs polyamide 66 (PA66).
