English to Russian Tech/Engineering Engineering (general) Power distribution systems

Добрый день!
Помогите, пожалуйста, перевести improvement in voltage drop в следующем контексте:

Bus and Battery Bus
Their main advantages:
› high electrical conductivity of pure aluminium and aluminium alloy,
› mass reduction compared to a copper solution,
› improved heat dissipation in comparison with a circular power cable bundle,
› significant improvement in voltage drop throughout the power distribution chain.

Заранее спасибо!
