Sate of the art of plug-in cable connectors for medium voltage cable systems in the federal republic of Germany
(-)Abstract
Originating In the USA, separable cable conne<:tors
have since spread all over the world. The tr~nd to
metal-.mclosed Nltchgear, on the one hand, and' the
meanwhile predominating use of slngle-core,plastlclnsulated
medlum~voltage cable, on the other, Indicate
that the demand for separable cable connectors
is likely to Increase. In the Federal Republic of
Germany this led to national designs being brought
out, partly based on existing versions, partly adopting
an approach of their own. The special features,
inter alia, are, for exc?tnple. the use of silicone
f ber as insulating material, in order to gain
imal adaptability to the surface of the cable
es on which stripping tools are used, and the
use of a metal enclosure.
To ensure compatability betw~n separable cable
connectors, a German 01mensional standard has been
drawn up, 'while a test standard to prove the
operational dependability is In preparation. In the
course of this process of standardization the
~uestion of protection against contact with live
parts will be dealt with. The Ger.nan manufacturers
are already offering a choice of different designs
for all applications and covering all users's requirements.
With separable cable conne<:tors it Is possible
to disconnect sections of cable for operational purposes.
