Towards a more flexible rating method for cables in tunnels
Towards a more flexible rating method for cables in tunnels
In recent years the use of cable tunnels in large urban areas has become more popular, with the additional capital cost becoming increasingly acceptable in light of the growing difficulties incurred for large scale directly buried cable installations. Presently cable ratings for such circuits are calculated using the method of Electra 143. However the applicability of this method is restricted owing to the assumptions made within the calculation, notably that all cables must be of identical construction and carrying equal load. This work demonstrates an improved method which removes this limitation whilst retaining the ease of use of the previous method.

Abstract
In recent years the use of cable tunnels in large urban areas has become more popular, with the additional capital cost becoming increasingly acceptable in light of the growing difficulties incurred for large scale directly buried cable installations. Presently cable ratings for such circuits are calculated using the method of Electra 143. However the applicability of this method is restricted owing to the assumptions made within the calculation, notably that all cables must be of identical construction and carrying equal load. This work demonstrates an improved method which removes this limitation whilst retaining the ease of use of the previous method.
