IP55 SANDWICH BUS DUCT

Entraco BKS bus duct and rising main are specially designed for commercial, residential, industrial and infrastructure projects.

Sandwich construction 415V 50Hz system

      - 3 phase 4 wire (100% neutral)

      - 3 phase 5 wire (100% internal earth)

Cables vs. Bus Ducts

Sr.no Issue Cable Busbar 1 Number of circuits One circuit per floor. Hence for a 20-floor building, you need 20 circuits. Just one circuit can cover all floors. 2 Main Switchboard Need 1 outgoing for each circuit. Hence 20 nos. MCCB outgoings. Higher cost and larger space requirement in electrical room Need only 1 outgoing for each riser. Lower cost and size of main panel. 3 Shaft Size Using 4 core cables, and considering 1 cable per feeder, you need 20 cables on the lowest floor. Large space required for cables/ cable tray. Typical size of 1600A riser is 185mm x 180mm. Leads to big savings on riser shaft size, and hence more usable floor area on every floor. 4 Fire & safety The high concentration of insulating materials used in cables and conductors involves a very high level of combustive energy The volume of insulating materials used in trunking is reduced to a minimum so combustive energy is considerably lower than cables. The insulating materials used do not release corrosive or toxic gases in the event of a fire. Once the source of the fire is removed, these materials are extinguished in a few seconds so that the effect of the fire is minimised. 5 Combustive Energy 1600A – approx 60 kWh/sq.m 1600A – approx 5 kWh/sq.m. Combustive energy is typically 80% -90% less than cables. 6 Future expansion If load on any floor exceeds initial plan, owner has to run an additional cable from a spare feeder on main board to that floor. . By providing extra tap off slots on each floor at the design stage, owner only has to procure a tap off box and plug it in wherever additional load is required. As the plug in can be done live, there is no shut down required for any of the existing clients / circuits. Future Flexibility. 7 Fault withstand levels Limited by conductor size of each circuit. Much higher – typically a 1600 A riser has a fault withstand capability of 60 to 70 kA. Safer in an electrical fault. 8 Installation time Much longer Each riser on a 20-floor building can be installed in approximately 2 to 3 days 9 Voltage drop High impedance if you choose cable size based on each floor current rating Much lower impedance. Hence substantially lower voltage drop.
