TECHNOLOGY

Pr ysmian Group has launched two new
525kV HVDC cable technologies, which it
says will enable more effi cient, reliable and
eco-friendly power transmission over long
distances.
The group has introduced two new 525kV
extruded land cable systems, one qualifi ed
with P-Laser and one with XLPE insulation,
following qualifi cation testing.
These cable systems are designed at a
higher voltage level and with large conductor
cross-sections to provide optimal technical
solutions for long-distance, high-power trans-
mission with minimised land use.
P-Laser is the fi rst 100% recyclable, eco-
friendly, high-performance cable technology,
utilising a ‘zero-gas’ process which reduces
CO2 emissions by up to 30%.
It is fully compatible with existing HVDC
cables and accessories, and has over
30,000km manufacturing experience in other
types of power cable networks.
The P-Laser qualifi ed cable system employs
a Pr ysmian in-house material called high per-
formance thermoplastic elastomer (HPTE),

STANDARDS
The European Plastic Pipe and Fittings Asso-
ciation (TEPPFA) has issued the fi rst Euro-
pean EN standard for oriented unplasticised
poly(vinyl chloride)(PVC-O) pipes.
The new voluntar y standard will create a
Europe-wide standard for companies manu-
facturing PVC-O pipes, where previously
there had been a variety of non-aligned na-
tional standards.
This new standard allows specifi cation
for PVC-O piping systems intended for wa-
ter supply use, pressurised (up to 25 bar)
drainage, sewerage, treated waste water, and
irrigation systems, either underground or

above ground where protected from direct

sunlight.

The standards include requirements for

the raw material, PVC-O pipes and fi ttings,

and their testing to fi t the designed purpose

of the system. Monica de la Cruz is chair of

CEN/TC 155, the European standardisation

committee for plastic piping systems and

ducting systems, where the new standard

was developed.

She said: “TEPPFA has been instrumental

in helping to bring this new standard into be-

ing and it will provide reassurance to speci-

fi ers that PVC-O pipes and fi ttings defi ned

within the standard are of a good quality and

fi t for their designed purpose.

“Oriented PVC is a remarkably strong

material and ideal for a wide variety of appli-

cations under pressure to contribute to im-

prove Europe’s water supply and waste water

infrastructures.”

TEPPFA is a partner organisation of

CEN/TC 155 and has been involved in

the development of many of the 221 CEN/

TC 155 standards currently in use, as well

as over 40 projects that are presently being

worked on.

which carries enhanced characteristics such

as increased thermal performance and higher

intrinsic reliability.

The XLPE qualifi ed cable system, mean-

have also successfully passed type tests at

600kV.

“This new milestone is a signifi cant step

for ward for power transmission systems and

the development of innovative and sustain-

able cable solutions in the industr y,” said

Hakan Ozmen, EVP of the projects business

unit at Pr ysmian Group.

“The 525kV cable systems can be an ef-

fective solution for the planned German

HVDC Corridor projects, providing the TSOs

(TenneT, 50Hertz, TransnetBW and Amp-

rion) with two proven technologies able to

connect the wind generation-rich regions of

northern Germany to the major consumption

areas in the south, reducing the required land

usage and ensuring a lower environmental

impact.”

Pr ysmian Group is playing a key role in

the connection of German offshore wind

farms to the mainland, having supplied and

installed multiple turnkey HVDC and HVAC

systems across German waters, with a track

record 4,100km of HVDC submarine and land

cables and more than 1,000 installed cable

accessories.
