NP The external gas pressure cables have been devel-
oped the early 1930ies.
The conductors are insulated with lapped and mass
impregnated paper insulation. considerable number installations
with this cable type service today. For this pur-
pose, nkt cables has kept the manufacturing facilities
and know-how provide the optimum solution. Over suitable bedding armour flat steel
wires applied. Three cores are cabled to-
gether.
Despite that, for re-routing and repair often
desirable install cables the same type. deviation the external
gas pressure cable the nitrogen gas forms part of
the cable insulation. there metal sheath,
the gas penetrates into the voids present the
mass impregnated insulation and prevents electrical
discharges. With the gas pressure acting the oval
shaped cable cores, formation voids prevented,
giving the cable the required electrical strength.
Like the external gas pressure cables, the demand
for new installations has decreased significantly. Thousands kilometres
are satisfactory service European high voltage
networks. They have proven their
reliability many decades.
Similar the external gas pressure cables service
experience with the internal gas pressure cables is
also very satisfactory. The three core cable pulled into a
steel pipe which filled with nitrogen gas bar
