• 60,100 & 125 Amps : Galvanised Steel.
• 200 & 315 Amps : Aluminium / Stainless Steel
• 160,250 & 400 Amps: Rolled Copper.

Shrouded Dsl Busbar System insulated conductor bar system are used for power transmission for mobile machinery. Current capacity ranges from 500 Amps to 2000 Amps rated at 100% duty cycle and 35°C ambient temperature with nominal voltage up to 600V. Insulated Conductor Bar provides safe and economical power for track guided mobile machinery.

V type DSL system is a modern power supply systems which are using single pole insulated conductor bars. The applications of this system are Traveling cranes, Transfer trolleys and special application used for high energy consumption under difficult conditions. The conductor material is as follows:

• Copper - 500 Amps, 800 Amps, 1000 Amps, 1250 Amps, 2000 Amps
• Aluminum with S.S Strip – 500 Amps, 800 Amps, 1000 Amps, 1250 Amps

The Aluminum conductor bar is provided with proven and patented stainless steel contact surface. For high temperature conditions a high temperature insulation cover up to 115° C is available. The phase conductor covers are yellow colour and earth insulation cover is green. The spring loaded current collectors can be used for horizontal / vertical installation in single or double version. Installation of conductor bar system is simple and maintenance is confined to a routine check of collectors.

• Safety : due to its isolation it is a protected line.
• Small dimensions.
• The differences due to expansion are absorbed in every joint of the line. It is not required to place special expansion joints.
• To extend an existing line is very easy just by adding new tracks.
• Quick mounting: in one pass the line is ready to work
• The electric feed can be done at the beginning of the line or at every joint of the line.
• It is very easy to change a track already assembled without moving the rest of them.
• Working voltage: up to 600V
• Working temperature: from -30ºC to +55ºC
• Degree of protection: IP20 (without rubber sealing). IP 23 (with rubber sealing)

• Extremely low power consumption of <5 Watts / Phase.
• Use of ultra-bright LED for Omni directional view from long distances.
• Clear indication of phase energized status of supply on the adjacent bus-bar.
• Low cost replacement of incandescent lamps which are generally used for this application.
