Utilities are finding
increasing need to operate their transmission and distribution cables
"closer to the limit" to wring every available ampere from an expensive
resource. Many issues must be considered to confidently rate the cables
near their ultimate limit. These issues include:
- How can I install
the lowest-cost system today, and still meet the required loadings
in twenty years?
- What are the
ampacity effects of different XLPE cable shield constructions and
bonding modes?
- Are ampacities lower
for cables installed by directional drilling? What are my options?
And what are the calculation procedures?
- Is ampacity reduced
by Installing extruded-dielectric cables in steel pipe?
- What are my options
for uprating cables ? How do I determine the rating of my existing
cables?
- Is soil thermal
stability really an issue? What about interface temperature vs. heat
flux density?
- Will fluidized
thermal backfill really increase ampacity and save me money?
- What are the effects
of hourly load profiles - daily vs. weekly periods?
- What are my options
for monitoring cables and using results effectively?
- I cannot change my
cable size. What are my options for optimizing the trench
cross-section, use of controlled backfill, etc. to obtain the
required ampacity?
