Skema was the first company in Italy in its sector to be awarded ISO 9001:2008
Quality System Certification and ISO 14001:2004 Environmental Management Sys-
tem Certification. Every aspect of Skema’s manufacturing operations and corporate
structure is driven by the Total Quality Management System, and the use of SAP as
the company’s ERP helps to monitor every detail.
Skema is registered with the First Point Assessment Limited (FPAL) System (Supplier
No. 10050005), the Utilities Pre-qualification (UVDB) Scheme (Supplier No. 85940),
and the Achilles Joint Qualification System (JQS Supplier No. 29594).
the cOmPany
Skema is a global market leader in
the design, engineering, manufacture
and servicing of complete integrat-
ed power distribution systems: local
equipment rooms, modular substa-
tions and powerhouses, medium volt-
age switchgear, intelligent low voltage
switchgear (LV switchgear and Intelli-
gent Motor Control Centers) and inte-
grated protection and control systems.
After more than 40 years in business,
Skema is recognized throughout the
world as being at the forefront of the
industry sectors in which it operates
and has by now built an extensive client
base around the world. Skema’s prod-
ucts and solutions are installed and op-
erate with success in over 50 countries.
Skema’s design, engineering and
man agement operations are located at
the headquarters in Cesano Maderno,
just 20 km north of Milan. This is
the place where project manage-
ment is carried out, where custom
solutions are conceived and where
support functions (administra-
tion, human resources, purchas-
ing and logistics) are implemented.
Just a few kilometers from Cesano
Maderno, in the plant at Bovisio
Masciago, Skema’s products are man-
ufactured, stocked and assembled.
The same location hosts also a dedicat-
ed training facility where technicians
from all over the world undergo spe-
cialist training. In the Yard in Ravenna
(on the Adriatic Sea, south of Venice),
local equipment rooms, modules and
pack aged substation are fabricated.
Skema also has a presence in Atyrau,
Kazakhstan (Skema LLP), Abu Dhabi,
UAE (Skema LLC), and in Maputo, Mo-
zambique (Skema SQ LDA), and has
sales offices in the following coun-
tries: UK, Egypt, Malaysia, Iraq, Ku-
wait, Thailand, Qatar and USA.

Skema’s Modular Substations can be
used for a wide variety of applications
including MV/LV packaged substa-
tions, local equipment rooms, con-
trol rooms, generator power plant
rooms, personnel refuges and as
general process or utility buildings.
They are fully assembled and rig-
orously tested within Skema’s fa-
cilities before being shipped to site,
by land, sea or air, ready for rap-
id installation and commissioning.
During the project, Skema acts as an
EPC contractor, managing, coordinat-
ing and monitoring every aspect of the
project: detailed design, project man-
agement, scheduling, procurement
and expediting, QA/HSE management,
documentation, fabrication, all multi-
disciplinary installation activities (ar-
chitectural, mechanical, E&I, HVAC,
etc.), and testing and pre-commis-
sioning at Skema’s fabrication yards.
Modular substations fitted with Ske-
ma-brand MV and LV switchgear can
be supplied with the following differ-
ent systems: insulation according to
fire rating; HVAC system; pressuri-
zation system including air filtering
systems, gas, smoke and fire detec-
tion systems; automatic fire-fighting
systems; special painting and coat-
ing systems; security, IT and tel-
ecoms; lighting and small power.
One of the most important and distinc-
tive features of Skema’s Modular Sub-
stations is the opportunity they afford
to create a unique and fully customiz-
able solution, in accordance with each
client’s individual specifications, the
environmental requirements, the envi-
ronmental conditions and the project-
specific transport size limitations.
Skema’s Modular Substations are
space-efficient, highly reliable and
fully integrated, and equipped with
the latest state-of-the-art technol-
ogy for Oil & Gas applications. They
are designed to work safely in harsh,
potentially explosive and chemically
contaminated environments, and are
intended for both onshore and off-
shore Oil & Gas / petrochemical plants.

Skema is a leading supplier of me-
dium and low voltage switchgear.
Skema’s range of medium volt-
age distr ibution switchgear is
composed of both metal-clad
and meta l -enc losed mode ls .
Skema’s low voltage Power Mo-
tor Control Center is a modular
system with fixed and withdrawa-
ble units for powering, controlling
and protecting low voltage motors
and feeders. It is particularly suit-
able for applications requiring high
performance, safety and a high lev-
el of reliability. The “intelligent” ver-
sion delivers some major benefits:
increased plant reliability and avail-
ability, reduced maintenance costs,
enhanced protection, centralized Inte-
grated Protection and Control System.
Skema’s switchgear can be used
in Oil & Gas fields, oil refiner-
ies, off-shore platforms, power
plants, utility companies, industrial
facilities and marine applications.
The main technical features are: with-
drawable and fixed functional units,
fully insulated and segregated bus-
bar system, internal arc proof, form
4 construction up to Type 7, seismic,
shock and vibration tested to with-
stand extreme operating conditions.
It can as well be supplied with tem-
perature monitoring and arc flash
detection systems. The modular
design allows the simplest and saf-
est cubicle reconfiguration on site.
Skema’s switchgear is fully compli-
ant and has been tested by independ-
ent laboratories in compliance with
IEC 61439-1.

The IPCS is a combination of software
and hardware specially designed to
control and monitor electrical pow-
er generation and distribution plants.
The IPCS monitors and supervises the
status of every incomer and feeder
(for MV and LV switchboards) through
the intelligent IPCD relays. The IPCD
signals are received and managed
by the RTU. The RTU, connected to
the LMS/DMS LAN and/or through
the DCS LAN, exchanges information
with the control room. An operator can
monitor and supervise the system by
connecting via a PC to the RTU or
directly to LMS/DMS ethernet LAN.
The IPCS controls the individual
switchgear equipment, the substa-
tion and the plant; acquires data from
all types of instrumentation using any
of the existing protocols; allows the
immediate transmission of com-
mands from the supervisor; displays
very detailed graphics and features
touch-screen interface; records con-
sumption and analyzes malfunctions;
displays and enables the operator to
change the setting of the protection
relays; manages and controls load
sharing and load shedding; manages
the maintenance of the plant; reports
any failures throughout the plant.
