independent internationally accredited laboratory.
-
- Busbar system shall have CE marking.
- Each product shall have a “Type Label”, which indicates the brand, type of the unit,
conductor number and electrical details
- Busbar system shall be Air-Insulated and Plug-in type. Aluminium or Copper conductors
shall be tin plated along the entire length. Housing shall be galvanized steel or if required
RAL 7038-Electrostatic painted.
- Busbar systems nominal insulation voltage shall be 1000V.
- As per ampere rates, minimum short circuit values shall be like below;
Temperature rise shall be maximum 50K over 40°C ambient temperature

- Busbar system shall be of air insulated type. The bars shall be supported by insulators
installed into the housing at every 25 cm.
- On a three meter standard length busbar the distance between the plug-in points on
one side shall be 50cms. The points shall be on both sides of the busbar making the
average distance of plug-in points 25cm.

2.1-
-
Manufacturing facility of busbar systems shall have ISO 9001 and ISO 14001
certification.
- To prevent wrong alignment of the phase sequence during installation there shall be
mechanical barriers on the joint that shall ensure correct mounting.
- IP Plug-in covers of the busbar system should be hinged.Plug-in windows shall have
automatic shutter system. This shutter shall open automatically when the earth contact of
tap-off box is inserted.
- Busbar system shall have all necessary accessories (elbows, offsets, panel-transformer
connections, reductions, etc). Manufacturer shall supply special dimensioned units in
short time, if the project conditions requires.
- For horizontal runs, a horizontal expansion unit shall be used at every 40m and expansion
points of the building.
- For vertical applications, a vertical expansion unit shall be used at every floor. Busbar
system shall be rigidly fixed by supports at every floor.
- Busbar system shall have Nickel and Tin-plated 6101 class aluminium conductors (160-
600A). / Busbar system shall have Tin-plated Electrolytic copper conductors (250-800A).
- Busbar system shall have below number of conductors and phase configuration;
a) 4 Conductors:(4 full size cond Housing ( earthing )
b)
(4 full size cond ½ earth con Housing)
c)
( 5 full size cond Housing (earthing) )
d)
( 5 full size conductors, 5th bar shall be used as clean earth + Housing).
- Neutral conductor shall have the same cross-section (100%) of phase conductors.
