STATE OF THE ART OF PLUG-IN (SEPARABLE) CABLE CONNECTORS FOR MEDIUM-VOLTAGE CABLE SYSTEMS IN THE FEDERAL REPUBLIC OF GERMANY
(-)
Abstract
Originating In the USA, separable cable connectors
have since spread all over the world. The tr~nd to
metal-enclosed switchgear, on the one hand, and the
meanwhile predominating use of single-core,plastlcinsulated
medium~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 example, the use of silicone
rubber as insulating material, in order to gain
~timal adaptability to the surface of the cable
~res on which stripping tools are used, and the
use of a metal enclosure.
To ensure compatability between separable cable
connectors, a German a1mensional 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 German manufacturers
are already offering a choice of different designs
for all applications and covering all users's requirements.
With separable cable connectors it is possible
to disconnect sections of cable for operational purposes.
