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