Three cores are cabled to-
gether. They have proven their
reliability many decades. considerable number installations
with this cable type service today.
Despite that, for re-routing and repair often
desirable install cables the same type. The three core cable pulled into a
steel pipe which filled with nitrogen gas bar
overpressure. deviation the external
gas pressure cable the nitrogen gas forms part of
the cable insulation.

Like the external gas pressure cables, the demand
for new installations has decreased significantly.
Although the demand for paper insulated cables has
decreased, for re-routing and repair often desir-

NP The external gas pressure cables have been devel-
oped the early 1930ies. With the gas pressure acting the oval
shaped cable cores, formation voids prevented,
giving the cable the required electrical strength.
The conductors are insulated with lapped and mass
impregnated paper insulation. For this pur-
pose, nkt cables has kept the manufacturing facilities
and know-how provide the optimum solution. For this
purpose, nkt cables has kept the manufacturing
facilities and know-how provide the optimum
solution. Each insulated core is
separately lead sheathed. 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
