ServiceS, philoSophy ...

It is designed for the production of connection-ready, pre-wired and functionally tested electri-cal products for the following areas:

▪ Low voltage switchgear ▪ Medium voltage switchgear ▪ Protection systems ▪ Automation systems ▪ Railway power supply systems ▪ Drive systems.

Our product and system production is hall-marked by a 4,000 m2 production area, flexible storage and logistics facilities and modern, high-performance test facilities.

Whether in small series or single-unit produc-tion, our job-oriented concept ensures efficien-cy and cost advantages with high quality pro-ducts conforming to national and international standards and ensures fault-free reliable use of our products.

For batch sizes starting at „1“, a modern CNC machine is used for completely machining mounting plates and a plasma cutter is used for making cutouts in doors and housings. This process results in cut edges with higher corro-sion protection. The CNC files are archived and are available for identical replicas..

In all implementation phases of a job our project engineer coordinates the required services, creates the project documentation and optimally steers the processes within the scope of the timetable and cost plan.

CAD programs: ▪ Eplan ▪ Ruplan ▪ Elcad ▪ AutoCAD ▪ COMOS etc.

The copper busbars for the switching systems are manufactured in our own workshop, which has the appropriate cutting, punching and bending machines.

Plastic or sheet metal covers for touching pro-tection, as per BGV A3 (VGB 4), are individually manufactured for every system.

We pack our systems and products to suit the particular requirements of the transport method - also for air freight, sea freight etc.

Our quality benchmarks are the satisfaction of our customers and the environmental compatibility of our products. The success of our quality control work is proven by regular certification of the quality management system as per DIN EN ISO 9001.

and quality

Our highly qualified technical workers, construc-tion managers and commissioning engineers are committed to delivering, installing and commissioning our systems on-time and to a high level of quality.

Our employees are also available for servicing tasks after hand-over of our systems.

Our modern equipment and CAE tools allow us to satisfy the most demanding timetables.

low voltage Switchgear

We plan and manufacture switchgear entirely in-house, as a license partner and to customer specifications with:

▪ Rated operating voltages up to 690 V AC ▪ Rated currents up to 6,300 A ▪ Rated short-term peak currents of up to 160 kA Icw (1s) ▪ Feed-ins, couplings and outputs ▪ Fixed installations, plug-in and withdrawable technology ▪ Protection types up to IP 54 ▪ Cable and / or busbar connections from above / below.

The use of manufacturer-independent electrical devices and a free choice of housing system form are the basis of our optimum PTSK so-lutions.

protection SySteMS

For power supply systems we manufacture:

▪ Protection cabinets for 220 kV and 380 kV grids

▪ Protection and control cabinets for the 110 kV grid

▪ Protection and control cabinets for the 110 kV wind feed-in substations.

10

autoMation SySteMS

We manufacture expert automation solutions on a range of different system platforms:

▪ I/O stations ▪ PLC cabinets ▪ Server cabinets ▪ Video cabinets ▪ BOB system components ▪ Switch gallery equipment.

A comprehensive selection of special tools allows us to crimp all commonly used contact elements and we can ma-nufacture

▪ Thermi-Point connections ▪ Connections using wire-wrap and

insulation-displacement systems.

11

In the railway power supply sector we develop, produce and deliver DC switchgear for local transport authorities.For rectifier substations we manufacture:

▪ Station service plants ▪ Rectifiers ▪ DC switching cells ▪ Fast switching modules.

The Elpro products are certified and conform to the relevant DIN EN standards. They are desig-ned for use in railway power supplies with rated voltages of 750 V GS and 1500 V GS.

As a Q-1 supplier we manufacture 15 kV swit-ching points (16 2/3 Hz) for the Deutsche Bahn.
