Los valores indican el número de cables, cuando las canaletas están llenas al 50%. Los valores orientativos de los diámetros de cables, tienen como punto de referencia los cables CYKY.
Los valores se obtienen mediante cálculo matemático. En el caso de valores extremos (canaleta pequeňa x cable grande o al contrario) es necesario evaluar las combinaciones de tipo de canaleta y diámetro de cables y escoger, tomando en cuenta las condiciones técnicas.
