Background

New electric transmission

capacity is needed to support

policies to retire older fossil

fuel based power plants

expand access to renewable

generation resources and

maintain reliability

Significant public opposition

to overhead transmission

line construction has raised

legal and permitting barriers

that can severely delay

new projects

Factors commonly cited

against construction of new

overhead transmission lines

Aesthetics

Land use constraints

EMF

History of Polymer Insulated Cable Systems

for Transmission

1970s Deliveries of polymer insulated (ldquoXLPErdquo) cable systems for voltage ratings up to 145 kV

1980s XLPE transmission cable systems rated 230 kV

1990s XLPE transmission cable systems rated 345 kV 420 kV and 500 kV

bull Length 69 miles of new

345-kilovolt (kV) line

bull 45 miles of overhead

bull 24 miles of underground

Polymer Insulated Cable Systems for HV and

EHV Transmission

Charging current in AC cables increases cumulatively with distance (For example 25 miles of 345 kV XLPE cable requires approximately 600 A charging current)

Capacity to transmit real power diminishes with distance limiting the practical length of AC underground and submarine cable transmission circuits

HVDC cables carry charging current only during energization

7

History of Polymer Insulated Cable Systems for

Transmission




1999 The worldrsquos first polymer insulated cable system for direct current transmission

8

Application

Connect a new onshore wind power

facility on the southern part of the island

to Gotlandrsquos main load centre

Fast reactive power regulation to

support integration of wind power

facility to the islandrsquos grid

Solution

43 miles long 160 kV (plusmn80 kV) 50 MW

HVDC underground cable circuit (HVDC

underground cables made it much easier

to obtain permits for the new line)

Compact HVDC voltage source

converters that provide dynamic voltage

support to the islandrsquos AC grid

Rapid Cable Installation Method

bull Innovative method to install HVDC cable designed to

minimize cost while maximizing production and schedule

bull Train of equipment to trench install cable and backfill

bull Uses existing corridor

ndash Known geotechnical information from previous utility work

ndash Minimize clearing additional access permits ROW issues

environmental impact

bull Safety

ndash No open trench ndash less risk to people and wildlife

ndash Minimal crew size

18

Rapid Cable Installation Method (cont)

bull Quality

ndash Consistent trench depth

bull Depth gauge on trencher

bull Depth mark on box plow

ndash Even cable separation

ndash Uniform thermally

acceptable backfill ndash

custom designed plow box

with vibrators to ensure

proper bedding cover and

compaction

bull Minimal weather

susceptibility

ndash Decrease potential cable

damage due to exposure

since we backfill

immediately behind cable

laying

ndash Short lag between

operations so minimal

exposure if cable

operation has to stop for

any reason

19

Assumptions and Things to Consider

bull Assumptions

ndash Reasonably flat terrain with suitable soil for rapid trenching

ndash Thermally acceptable backfill ndash 28rdquo x 1 ft

ndash Occasional rock can be trenched through

ndash 35 ft min corridor needed

ndash 2000 ft avg reel size

bull Things to consider

ndash Obstructions

ndash Congestion of existing utilities

ndash Corridor widths

ndash Existing foundations in the right-of-way corridor

ndash Access points for cable delivery

20

Typical Overhead Right of Way

21

Execution Plan

bull Goal install 8000 ft of cable per day

(four reels at 2000 ft per reel) in optimum conditions

bull Four simultaneous operations

ndash Trenchingcable layingStokbord

ndash Backfilling remaining trench

ndash Procuring thermal fill material

ndash Cable handling

bull Subsequent operations

ndash Splice pit excavation and set splicing box

22

TrenchingCable LayingCable Protection

bull Use a large trencher with a specially designed plow box

ndash Cut 28 in wide x 45 ft deep trench

ndash Place 35 in thermally acceptable fill

ndash Place two 5 in cables 10 in apart

ndash Place 3 in thermally acceptable cover over cables (12 in total)
