Busduct & Busbar New Developed Solution
High Voltage and High Current Insulation Tubular Bus-bar System
Most effective for transferring large amounts of energy associated with complex shielding busbar.
1. No visual inspection
2. Environment impact vulnerable to excessive outer section(Wind pressure / corrosin etc)
3. Increase in relative height with top entry
We solve above problems and add more benefits:
New Developed Solution
1. Easy maintenance by visual inspection
2. Minimal environmental impact due to minimization of outer section
3. Top or bottom entrance available
Transferring large amount of energy. (voltage & current)
Main insulation material is have excellent temperature characteristics and chemical stability
no need for additional cooling devices
Self ventilation system
Copper Type : Max. 35kV(Nominal Voltage) / 9000A
Aluminum Type : Max. 35kV(Nominal Voltage) / 5000A
Application & Installation
-The various applications to the installation conditions.
(trifoil formation / narrow spaces / s-bending)
Available to top & bottom entry in cubicle
Safeguard (cover) for the protection of New Developed Solution. (option)
Assure complete isolation.
In the event of unexpected accident, the impact can be less compared to conventional system due to strict phase separation.
Safe from the contact of human or metal objects.
Maintenance can be executed through visual inspection without power cut
Simple and easy maintenance because of the relatively not many connection points.
Annual inspection contract is possible throughthe thermal imaging equipment.(option)
Tests Are available
Power frequency withstand voltage test
Partial discharge test
Temperature rise test
Insulation resistance test
Dielectric strength test
Leakage current test
VIP Best Solution
Cable Solution Problems

NEW Developed In compare with NSPB for distribution panel
|Excellent Stability, due to the relatively less connection points
No Rise of temperature by using round clamp.
|Rise of Temperature can be occurred due to many connection points & connecting between rectangular bus-bars.|
|* In case of ‘22.9kV 4000A 30m / Phase’,
(1) Indoor : 20m long Connection
Point – 3 points
Point – 2 points
|* In case of ’22.9kV 4000A 30m / Phase’,
(1) indoor : 20m long Connection
(2) outdoor: 10m long Connection
|No or less over heat and eddy current with using one line per phase.||Using many rectangular bus-bars, for transferring large amount of current,
-> over heat with partial current integration can be occurred after long time operating.
|* 22.9kV 4000A Capacity
120ф * 6mm * 1 Core / Phase
Dimensions : A-350, B-320, C-1300
|* 22.9kV 4000A Capacity
12T*100, 3Sheet / Phase
Dimensions : A-325, B-700, C-1300
|No needs of Additional enclosure for safety||Additional enclosure for safety is needed essentially.|
|- Only Simple and easy visual check OK||- check and maintenance points load is heavy.|
|Reduce length of vertical section by adapting bottom entry method.
- be influenced less with outdoor conditions( wind/heavy snow/etc.)
- Smaller diameter(150mm) and individual installation can
reduce influence of outdoor conditions.
|Relatively long vertical section and heavy enclosure by adapting top entry
may increase influence of outdoor conditions.
- Large impact on the building.
|Tubular type can be bended without elbow and offset parts
and so the accident due to partial over heat is not occurred.
|Possibility, partial over heat due to Concentration of electric field
is high in elbow and offset parts which is bended by a right angle
