Metro electrification system 1,5KV - rigid catenary

Overhead Rigid Catenary System:It delivers the traction current to the metro trains via its pantograph. It contains aluminium rail, contact wire, and all type of fittings (cantilevers, rigid portals, headspans, etc.), connections, section insulators, and all catenary equipment.Lifetime High Voltage Switchboard: TECHNICAL REQUIREMENTS (ERT) 5) OVERHEAD rigid contact wire due to temperature changes. Feeder Messenger System Type of overhead catenary system which uses a large cross-section to more easily pass the current for the messenger wire. Also has the function of feeder wires. Dropper Fitting used to suspend the contact wire from the Overhead Railway Electrification Systems - EMSPECAn important product line for EMSPECs activity is its overhead catenary system for electrified rail transportation systems. EMSPEC manufactures overhead catenary components employed in urban metro applications, tramways, passenger rail and high Installation of rigid overhead catenary in Crossrail Sep 07, 2018 · Figure 6:Details of Hanger Clamp. 3.2 ROC bar. The Rigid Overhead Catenary bar is an aluminium profile supported from a hanger clamp by insulated cantilever arm and a drop tube support fixed to tunnel roof (as previously described), that accommodates a 150mm 2 copper contact wire. The nominal length of a standard bar will be 10m which is also the maximum length of the bar, so the Electrification - rail systemRigid Catenary (or Overhead Contact System) The rigid catenary is an Overhead Contact System (OCS) that can replace, with many advantages, the contact wire with sustentation wire, the third rail or the suspended bimetallic T-rail. It Continue reading Overhead Contact Lines and Signaling Systems for Public TROLLEYBUS OVERHEAD CONTACT LINES. Suspension ropes, fiberglass or steel cantilevers, electrical and mechanical switches, trolley and wire-tram crossings, armatures, insulators, section insulators. RIGID CATENARY. fixed or mobile rigid catenary, ideal for depots. SIGNALING AND SWITCHES FOR TROLLEYBUSES. ROCS - Furrer+FreyThe rigid overhead conductor-rail system must be integrated in an existing catenary system. We have developed the transition bar in order to do this. The transition bar takes up and absorbs the oscillations from the contact wire of the catenary system and reinforces HTETCO Catenary Wire Used in Overhead Catenary HTETCO Catenary Wire Used in Overhead Catenary Systems for Light Rail Construction continued 24 American Society of Professional Estimators ASPEnational This lump sum amount includes material, labor, and equipment to perform the scope of work stated. Percentage of Journeyman's Pay 85% 11.3% $ 22.37 $26.32 $29.29 CN103192740A - Rigid movable overhead line system below The invention relates to a rigid movable overhead line system below an electrified railway coal hopper bunker. The existing movable contact line system generally driven by gear and rack or sprockets jams easily by accumulated dust, operation of locomotive pantographs has security problem, independent operation steps are required, and potential hazards caused by manual misoperation exist. Dynamic interaction between pantograph and rigid overhead Mar 01, 2016 · Most studies on the interaction between pantograph and overhead contact systems refer to the conventional catenary composed of contact and messenger wires and droppers, whereas the literature related to the interaction with rigid overhead conductor rails is limited. overhead contact system _JYTOP® Cable Manufacturers and Rigid Catenary (or Overhead Contact System) Rigid Catenary (or Overhead Contact System) The rigid catenary is an Overhead Contact System (OCS) that Garage Doors and Overhead Doors CHI Overhead C.H.I.
