DSL SYSTEM ALSO KNOWN AS DOWN SHOP LEAD SYSTEM

Conductor Power Bar (DSL SYSTEM)Components & Specifications

Power supply to the runway electrification shall be by means of bridge conductors and collector system as shown above. The typical components and specifications are as follows:

Conductor Bar – Track are super finished and cross section is maintained to achieve required Ampere.The material for track is GI,Al/SS & Copper.

Conductors shall be accurately aligned to ensure positive electrical contact between the collector and the conductor. Separate conductors shall be provided for each phase. More than one conductor in a single enclosure will not be permitted.

Maximum voltage drop from the building power takeoff point for the track electrification system tothe hoist motor shall not exceed 4 percent, and the equivalent conductance shall not be less 

Size of bridge conductors shall be proportioned to limit the total voltage drop in the conductors to a maximum of 3 percent of the supply voltage when the current on the individual motors is full load.

Power feed – This is an attachment for incoming power and is a fully insulated simple clamp type is easily installed anywhere on the system for incoming  power to the conductor rails. The power supply to the runway conductors shall be controlled by a switch or circuit breaker located on a fixed structure, accessible from the floor, and arranged to be locked in the open position.

 A fused, manual disconnect switch with a lockable handle mounted through the panel door shall be provided and wired into the incoming power circuit.

All power for crane shall be supplied through one main visible blade fuse switch located  on the crane bridge in an easily accessible position.

3) Collectors - Current collector assembly consists of a spring loaded sliding contact type shoe of hard copper alloy or sintered copper graphite.

Shoe shall be mounted in an insulating case of phenolic or urea compound of suitable temperature and insulation quality. Exposed parts of current collectors shall be grounded and of corrosion-resistant material.

 Current collector assembly shall be designed to operate through gaps, splices, and switches and shall be self-centering. System shall include expansion sections for every **0 meter for systems using galvanized steel conductors and every **5 meter for systems using copper conductors.

4) Hangers- Supports the conductor bar, may also be used as an anchor to direct movement due to expansion and contraction

5) End Cover- Used to close the end of the conductors to cover exposed conductor and avoid accidental contact.

6) Insulating cover –Insulation cover shall be rigid PVC, self extinguishing, with a heat distortion point of **0ºF at **0psi.

7) Connector pins - Used to join the conductor bar sections together . System shall be complete with unit length conductors, insulating conductor covers, insulators, splices and splice covers, end caps, support brackets and fasteners, current collectors, expansion, isolation and power-interrupting sections, disconnect switch, and conduit and wiring to power takeoff point.

We manufacture Dsl system ranging from *0A to ***0 A 

Advantages Of Our Dsl System

1.Dip of the track is maintain properly for movement of Current collector

2.Center Powerfeed is provided to decrease voltage Drop

3.The play between Track & Sleeve is Minimum

4.Current collector is provided spring steel with max dia to avoid breakage

We give Test certificate & Warranty Certificate for Dsl system & There erection for Period of 1 Year
