Gas-insulated switchgear
Flexible combination, reliability, availability and economy are
the attributes that make it easy for our clients in industry and
utilities to decide in favor of products from the ZX series.
Together with complete conventional solutions, the use of
digital protection and control technology, sensor systems
and plug-in connections makes ZX systems unrestrictedly
fit for the future, and the primary function of reliable power
distribution is fulfilled with no ifs and buts. This is ensured by
ABB’s uncompromising approach to quality, which leaves no
customer’s wishes unfulfilled.
- Systems in metal-enclosed design
- Hermetically sealed pressure systems –
gas-tight for life!
- SF6 insulating gas for guaranteed dielectric strength
- Metal partitioning between functions where necessary
- Plug-in technology for cables, busbars and
voltage transformers
- Enclosures in stainless steel
- Vacuum circuit-breakers
- Factory tested quality
A strong family for all situations in life.
Aligned to each need, the members of
the ZX family offer a solution for each
requirement. In over 70 countries the
customers rely on gas-insulated switchgears from ABB.

ZX offers maximum economy
ZX ensures maximum operator safety
The compact design of the panels reduces the space required
and therefore the size of the station. Freedom from maintenance is achieved by constant conditions in the high voltage
compartments in conjunction with the selection of suitable
materials. As a rule, therefore, isolation of the switchgear to
perform maintenance work is not required. The panels are
designed for an expected service life of over 40 years. Thanks
to the plug-in technology applied in the areas of the busbars,
cables and secondary systems, extremely short installation
times are possible. No gas work is required as a rule at site.
All live components are enclosed to prevent accidental contact. As the high voltage compartments are independent of
external influences (degree of protection IP65), the probability
of a fault during operation is extremely low. As evidenced by
arc fault testing, our switchgear systems are notable for maximum operator safety. A further enhancement can be achieved
by providing pressure relief to outside the switchgear room.

The plug-in busbar technology without screw couplings
permits simple and therefore safe assembly. In spite of the
extremely low failure probability of the ZX switchgear systems,
replacement of components in the gas compartments and
therefore a rapid return to service after repairs is possible.
In gas-insulated switchgear, earthing of switchgear sections
is performed by a high quality vacuum circuit-breaker. The
circuit-breaker can close onto a short-circuit significantly
more frequently and reliably than a positively making earthing
switch.
