Combining Forces
Siemens is investing in research and development in order to
manufacture the products you need now and will want in years to
come. Decades of experience in high-voltage equipment go into the
design and production of our products and set international trends.
No matter what your application is, our high-voltage products
provide the best solution for your requirements every time.
With our high-voltage centre break disconnectors and earthing
switches forrated voltages from 72.5 up to 420 kV, we fulfill
customers demands for reliabili-ty, safety and cost-effectiveness.
By combining the strengths of our well provenproduct portfolio, we
can provide this type of centre break disconnector.
By using the well-known maintenance-free contact system from
Ruhrtal, we took the best of what disconnector technology has to
offer and designed a family of disconnectors especially for your
specifications. We meet the high standard of quality that Siemens
is known for combined with our customers requirements for
cost-effective disconnector products. With this centre break
family, you have a reliable competitive solution with complete
safety and peace of mind.

3Our centre break disconnector family is available for rated
voltages from 72.5 kV up to 420 kV. The centre break disconnector
is the most frequently used discon-nector type worldwide. The base
frame (4) carries the compact operating mecha-nism (5) and two
rotating base mounted supporting insulators (2). In the closed
position, the current flows via the current path arms (1), which
are fixed to the insulators. The disconnector opens in the centre,
thus providing an insulating distance.
Each rotating unit (3) comprises two high quality sealed
ball-bearings and is de-signed for high mechanical loads, therefore
providing a maintenance free service life. These qualities result
in low service and investment costs which provide our customers
with competitive advantages worldwide.

The Contact System
The main contact system has been adopted from the well
established range of Ruhrtal high-voltage dis-connector products.
This system consists of block contacts and spread contact fingers
and assures a steady contact force even after decades of operation.
The current flows in the contact head from the terminal (7) to the
current path tube (6) through highly-flexible copper leads (8).

The most significant features are:
Self-resilient contact fingers, no further spring elements
necessary to generate the contact force
Factory-set contact forces, no re-adjustments required during
service life
Ice layers up to 20 mm can be broken without difficulties
Silver-plated contact surface providing highest conductivity
without regular grease lubrication
Maintenance-free contact system up to 25 years
By using the well-established blockfinger contact system, we
provide our customers with very practical advantages: smooth
operation, exemplary availability and optimum security.

The Earthing Switch
5
Three-pole centre break disconnector with earthing switch in
inboard design
The use of earthing switches ensures absolute safety by
grounding and discharging all high-voltage com-ponents in a circuit
or switchgear. Suitable built-on earthing switches are available
for the complete range of our centre break disconnector types from
72.5 up to 420 kV.
-
6Motor Operating Mechanism
The motor operating mechanism includes all components required
for operating the disconnector and consists of three main
subassemblies:
1 Corrosion-resistant housing (protection degree IP 55)
2 Gear unit with motor
3 Electrical equipment with auxiliary switch
The motor operating mechanism can also be operated manually by a
hand crank which can be inserted inside the cubicle. The insertion
of the hand crank automatically isolates the motor circuit for
safety pur-poses. Heaters are provided to prevent condensation.
