Third Rail Power Switches & Distribution Products
MAC provides the industry’s most complete selection of high quality, high performance, third rail power and
disconnect switches.
We manufacture a wide variety of manually operated and motorized sectionalizing switches for DC power
applications; bolted pressure design and knife-blade style. Switches may be designed to incorporate
electrical interlocking to prevent operation when voltage is present. These units can be tied into SCADA
systems for remote operation and monitoring.
MAC Products’ DC Load Break Switch is specifically designed and manufactured for traction power
applications with 1000 Volts DC and current up to 6000 Amps. The Load Break switch is motor operated and
can be controlled remotely or locally. Further, the switch does not require time consuming safety checks to ensure the track is de-energized or that current is not flowing prior to operation.
Third Rail Connection Accessories
MAC is a leading producer of compression, solder and mechanical connectors for a wide variety of mass
transit applications. We can design and manufacture connectors for your particular application.
We offer a complete range of cast and tubular compression lugs and connectors, for use in a wide range of applications. MAC lugs and connectors are installed throughout the world in thousands of locomotives, transit cars, LRV’s and other transit equipment.
MAC manufactures a variety of Copper Signal and Power Bonds for Signals and Communications use; each
bond can be customized in length. Our bond welds can be used for welding copper to copper and steel to
copper, the connections are a molecular weld and not just a superficial contact.
Stinger Energy Delivery Systems
MAC Stinger Energy Delivery Systems employ leading-edge technology to assure system safety, ease of operation, and reliability.
Most transit maintenance and repair shops currently handle their auxiliary power stingers under live conditions even when they are not being applied in the train. Unsafe open and exposed current conductions, poor track operating trolley systems and flat current collecting surfaces result in dangerous conditions that often lead to serious injuries.
In response to mounting injuries and other safety issues related to auxiliary and power stingers, MAC has developed an Energy Delivery System (EDS) that uses cutting-edge technology to promote safety, ease of operation and reliability.
OEM Electrical Components and Renewal Parts
MAC offers a full line of electromechanical component parts used in propulsion and electrical systems for
locomotive and transit car builders.
Components include but are not limited to blowout coils, contact tips, bus bar, DC Contactors and components, armatures, connectors and harnesses.
We design and manufacture parts that meet customized requirements or we manufacture to our customers drawings and specifications. Our engineers, technicians and machinists can deliver any type of power distribution component for us in locomotive, people mover, light rail vehicle, transit car or other systems.
Overhead Catenary Systems
Through a partnership and manufacturing agreement with Kummler+Matter of Zurich, Switzerland; MAC offers the Adaptable Railway Cantilever System (ARCAS) for light rail, tram, electric trolley bus, streetcar and commuter railway systems to customers in the U.S. and Canada.
ARCAS is a modular system consisting of multi-functional components. This modularity, together with the system’s compatibility with existing products, makes it easy to implement conversions to overhead electrification systems.
The Tensorex Spring Tensioner is an innovative tensioning device for Overhead Catenary System (OCS) that provides constant pull force on the messenger and contact wires while compensating for the its elongation or contraction due to temperature variation. Through our partnership with Pfisterer this tensioning device offers several significant advantages over a traditional balance weight assembly. It is safer because the device is mounted at the wire termination height, which is away from pedestrian reach. It is more compact and lighter, which translates to reduced installation time and visual impact. It is also a cost effective solution as the unit is self contained, requires less maintenance and easy to transport to the installation location.
Since 2008 there have been over 4,000 units installed worldwide with no failures. The Tensorex Spring Tensioner is expected to provide long uninterrupted service based on the intense tests that it was subjected to - fatigue, ultimate tensile strength, snap release, efficiency and salt spray.
Overhead Catenary Systems Projects
MAC provides the complete OCS system; cantilevers, balance weight assemblies, fixed terminations, head spans, pull-off assemblies, mid-point anchor assemblies, section insulators, jumper assemblies, hanger assemblies and pole brackets.
MAC Products has worked with multiple OCS contractors in the United States, on many varied projects over the years. These projects have incorporated the design, manufacture and installation of the complete light rail system. Recent projects that MAC has been involved with are:
- LA EXPO II Project, a 6.6 miles extension, connecting downtown Los Angeles to Santa Monica, California
- CENTRAL MESA, Phoenix Project, a 3.1 miles double track extension, which was completed 7 months ahead of schedule
- NORTHWEST EXTENSION, Phoenix Project, a 3.3 miles light rail extension.
- TORONTO TRANSIT COMMISSION, Ashbridges Bay Maintenance and Storage Facility
- WASHINGTON DC STREETCAR, H Street and Benning Road, a 2.4 mile segment between Union Station and the Anacostia River
