pkag Paul Keller Engineers - Railway Electrification

pkag Paul Keller Engineers specialises in the engineering of power supply networks for railways. The engineering includes overhead conductor rail, earthing and earthing return circuits, potential equivalent circuits, energy concepts, overhead lines and cables as well as software products. pkag Paul Keller Engineers also offers a range of surveying services for civil underground engineering.

Founded in 1973 as an independent engineering office for the electrification of railway systems, the company has approximately 30 employees from the fields of energy, mechanics, surveying and electronics. As a member of well known organisations such as Swissrail, usic, SEV, ETG, SGK, VIA, STV, VAP, OSEC and SEA, we are able to join syndicates or to work as an independent office. Our activities cover:

• Consulting
• Calculations
• Studies
• Detailed planning
• Projects from the first study up to the final acceptance
• Site management
• Measurement
• General planning
• Environmentally compatible expertises
• Instruction and training

Since 1994, the company has been certified by TÜV according to the quality management system EN ISO 9001.

RAILWAY POWER SUPPLY NETWORKS

At more than 300km/hr, the flow of energy between an overhead contact line and a current collector is an incredibly complex operation. This is our main business area, from preliminary studies to commissioning, and we ensure that this rapid contact is secure. These installations are made for a range of railway applications, including high-speed and light railway systems, maintenance halls and car depots, loading areas, and connecting tracks.

UTILITY POWER SUPPLY NETWORKS

How does the energy come from the power station to the consumer? In our field of business, the power network consists of overhead and cable lines, switching stations, low-voltage switching stations and substations. In addition to the economic basics, we take care of preserving the environment. The planning of networks is made with the latest technology and tools.

NETWORK CONTROL AND TELECONTROL

The engineering department for network control and telecontrol covers all steps for the successful realisation of network control and telecontrol systems. These systems are designed for the best availability. The scope of our activities covers planning, supervision of production and on-site tests as well as commissioning for railway and control systems, PLC programming, automation and telecommunication systems.

CIVIL UNDERGROUND ENGINEERING AND SURVEYING

Our civil engineers' extensive experience includes all activities within surveying, such as photogrammmetric surveys, standard surveys, terrain surveys and geoinformatic surveys. The civil department is responsible for the control ground anchors, cable trays and blocks, test measuring, foundation construction, water supply, road construction and railway track construction. We can plan and realise water supply and recycling systems for the public or private sectors.

Although our policy is guided by our clients, the goal of all our activities is to search for creative, economic and durable solutions.
