- Position: 100% rating for any horizontal or vertical orientation.
- The maximum hot-spot temperature rise at any point in the busway at continuous rated load
shall not exceed 122°F
3- Components
3.1- Housing
- KX III–UL Busway system has “Sandwich-Compact” structure. Conductors are packed and
placed into the housing without leaving air gap in order to provide low reactance.
- The housing shall be RAL7038-Electrostatic painted extruded aluminum to provide maximum
protection against corrosion from water and other contaminants normally encountered during
construction.
- The busway housing shall be of 100% aluminum construction to reduce hysteresis and eddy
current losses.
- Busway housing shall have optional powder coating finish if required per project design,
- “Compact structure of the housing has been provided by M6 screws applied at every 7.48 in
along the entire length.
- The sandwich-compact structure continues at the plug-in points too. There isn't any air gap
between conductors at the plug-in points.
- The housing material and paint are selected with non-propagating properties.
3.2- Conductors
- Conductors: Individual isolated and insulated. Aluminum or Copper conductors are epoxy
coated. All phase and neutral conductors joints and contact surfaces are plated tin (optinal
Silver).
- Straight sections of feeder busway can be supplied in any length, from a 12.00-inch (350 mm)
minimum to a 10-feet (3048 mm) maximum
- Bus bars shall be suitably plated at all joints and contact surfaces.
- KX III–UL busway system has aluminum conductors between 400A – 5000A,
- KX III–UL busway system has copper conductors between 630A – 6000A,
- KX III–UL busway system has the following number of conductors and wire configuration;
A, 4½ Conductors: (4 full size cond PE (50% earth con housing)).
b. 5 Conductors: (4 full size cond PE (100% earth con housing)).
c. 6 Conductors: (5 full size conductors ( + PE (100% earth con housing)).
3.3- Insulation
- Insulation system is suitable for 600 V continuous operation.
- Specially formulated Class B epoxy insulation has been applied as insulation
material which provides high insulation resistance and high peak temperature
resistance.
-The insulation process apply is the spray insulation process which produces
uniform application of the epoxy powder over the entire conductor bar. It is further
enhanced by inline filter process and magnetic separator that help to eliminates
contaminants common to fluidized bed systems.
- Epoxy is UL V0 class and halogen and toxic free properties.
- All insulators must be UL recognized.
3.4- Joint Structure
- Electrical and mechanical connection is making by placing conductor joints
into the joint blocks of the connected conductors and followed by tightening and
fastening of the joint bolts.
- KX III–UL Busway also includes special EAE belleville spring washer be provided
to give positive pressure over complete contact area, that retains its original
contact pressure ensuring proper
electrical contact. Offers securer, more reliable and virtually maintenance-free
joint.
- All parts of the joint structure are plated with tin against contact losses due to
corrosion in order to get safe and reliable earth connections and have very low
resistance values entire length.
- It shall be possible to make up a joint from one side in the event the busway
is installed against a wall or ceiling. The joint shall be so designed as to allow
removal of any length without disturbing
adjacent lengths.
3.5- Accessories and Components
- All conductive fittings including Tees, flanges, Reducers, Expansion joints and
Elbows etc. shall be of the same material from the same manufacturer.
- End pieces and end caps will be provided to install at the ends of each line.
- KX III–UL Busway system has all necessary accessories (elbows, offsets, panel-
transformer connections, reductions, etc.) EAE supply special dimensioned units
in short time, if the project conditions require.
- For horizontal runs, a horizontal expansion unit has been used at every 40m and
expansion points of the building.
- For vertical applications, a vertical expansion unit has been used at every floor.
Busway system must be rigidly fixed by supports at every floor.
- Horizontal runs of busway shall be UL Listed for hanging on 10-foot (3.05
meters) centers in any position. Vertical riser runs of busway shall be supported
with rigid and/or spring hangers in positions indicated on plans (max 16'/4.88
meters) centers.
4- Tap-Off Boxes
- Tap off points shall be easily modifiable for phase configuration and be safe for
installation and decommissioning while the busway is in its live state. All tap off
distribution points shall have safety
features prohibiting their installation while under load
- Plug-In busways have minimum 2 and maximum 5 plug-in points on each 10
inch length.
- Plug-in tap off boxes are suitable to install or removed from busways without
switching off the power on the busway.
- Contacts of plug-in tap off box are plated by silver.
- Tap off boxes are manufactured of sheet steel and epoxy painted.
- Plug-in tap off boxes have electromechanical safety interlock system. Which
means;
- Electromechanical interlock mechanism ensures that the tap off box cannot
be removed mechanically from the busway, when the switch is at “ON” position.
- Electromechanical interlock mechanism ensures that, cover of the box can be
opened, when the switch is at “OFF” position. It is possible to open the cover to a
special pin when the switch “on”
position, it is depending on customer requests
- While inserting the contacts of plug-in tap off box, earth contact makes the first
touch. While removing, it is disconnected last.
Final field measurements shall be made by the contractor prior to release for
manufacture to assure coordination with other trades.
The installer will follow all manufacturers' installation details.
