From the first planning onto construction - everything
from one single source!
In the first step, the switchboard installation's layout
is developed by our mechanical design department. Based on this
layout design, construction and internal installation plans will be
drafted by means of a CAD program and the control data for
sheet-metal -, copper- and cable production works are generated.
Our team’s field experience gained in many years as well as the
basic information gathered, allow production within a period of few
days only so that our manufacturing process times are extremely
short! Applying high-technology CNC plasma cutters for the
processing of sheet-metal, we are able to manufacture more than 25
switchgears a day. You can choose from different coatings in
various colours that allow you to individually design your
switchboards.
As regards copper works, you may have every confidence in the
know-how of our qualified staff processing around 400 pieces a day.
With its shortening, crimping and labelling functions of cable
cross-sections from 0.75 mm2 to 6.5 mm2, our CNC cable
manufacturing system allows fast finishing of the switchboards'
“interior fittings”. Thanks to a number of approximately 2,500
machine produced cables a day which is combined with a highly
productive number of handcrafted high cross-section cables, we are
in the fortunate position to dispose of all technical facilities
for a cost and time effective working. The mounting of low voltage
switchgears on racks, a solution that had been developed in and by
our company, allows a fast transportation and a safe handling
Our internal production flow is constantly being optimized. Only
this way, we manage to achieve cost-effective solutions at a
constantly high quality level. The certification according to the
standard ISO 9002:2000 may as well give evidence that we also feel
obliged to maintain these high quality standards in future. All
systems have been designed and tested as to comply with IEC/VDE
standards. Customer preferences exceeding these standards with
regard to design, material or additional regulations, will, of
course, be taken into account.
Our manufacturing sector – Interesting facts in
figures:
The SEG manufacturing sector covers an area of totally
5,000 m². Using around 45,000 km of control cables and 45,000 kg of
copper, 7,000 switchgears, a year, leave our company. In our
storeroom that is 500 m², more than 4,000 different mechanical and
electric components are always in stock.
We leave nothing to chance!
In accordance with the specific requirements of our
customers, we engineer, construct and install switchboard systems
of different types. All partially type tested switchgear
combinations will be designed in compliance with DIN VDE standard
0660 part 500 or IEC 439.
The most important technical data are:
- max. rated voltage: 1000 V
- max. rated current of the main bus bar: 6300 A
- short-circuit test as per ASTA – certification: 80 kA - 1
s/176 kA peak
- type of enclosure according to DIN VDE/IEC: IP42 to IP54
- variable bus bar system at the top/in centre/at the
bottom
Various designs
Fixed-assembly unit design
- Distribution panel with stationary mounted function
units.
- Incoming and outgoing devices are permanently installed.
- Disconnection compulsory when working at the distribution
panel.
Withdrawable unit design
- Distribution panel with detachable function units
(withdrawable trucks or racks).
- Switchgears allow disconnection from current circuits under
voltage.
Different types of subdivision
- Internal subdivision into so-called “compartments” (form 1 –
4; IEC 439) by means of partition walls and coverings.
Purpose of protection
- Protection from direct contact with neighboring function
unit.
- Protection from ingress of firm foreign substances within the
function unit.
- Protection from accidental contact with hazardous components
within the function unit.
Effects
- Reduction of risk to people and system during connection,
service and maintenance.
- Local failure limitation, thus quick re-availability of the
whole system.
