The horizontal double break disconnectors consists of
three poles. Each pole consists of a frame, two supporting
insulators at each end and one rotating insulator in
the centre, on which the main blade is mounted. The types
TFD and TFX are for outdoor, the type TID for indoor
use.
They can be equipped with insulators in accordance
with DIN, IEC or other specifications.
The double break
disconnectors are operated single-pole or three-pole
by means of a motor or manual operated drive mechanism
inside an IP54 housing, with torques up 850Nm and including
up to 10 auxiliary contacts for position indication.
Optional earthing switches can be build-on to the horizontal
double break disconnector to the right hand side and/or
to the left hand side.
All disconnectors are designed and
tested in accordance with latest IEC specifications.
