CABLE BUS ENCLOSURE DIMENSIONS
Every cable bus system is designed to ensure efficient and reliable performance. We also custom build cable bus systems with different dimensions where space restrictions exist at project sites.
The reference figures shown are the typical arrangement of power cables in a multi-layered cable bus system. Ampacity is based upon 90°C operating temperature. The systems shown on this page are a small selection of what we do; for voltages of 35 KV, 69 KV, and higher please contact Harbor Energy Solutions.
