Energy installations – Hydro power, wind power and sun power

Busduct and busbar systems are a preferred solution in many energy installations. This due to the compact design, flexibility and technical advantages for collection, transmission and distribution of energy in a electrical system. With busbar trunking systems you can tie together the different components in any energy system and ensure a reliable transfer of higher and lower loads.

Hydro Power

Busbars are a compact and safe solution for transmission from aggregate to GCB and to transformers.

Wind Power

Busbars are the preferred solution for internal connections at both high- and low-voltage levels at HVDC platforms and other systems related to wind power.

Sun power

busduct are a compact and reliable solution to collect, transfer and distribute energy.


  • Metal clad 1000V
