Power Busbars / Busducts / Bustrunking

(A) Sandwich Bustrunking System

M.B. Automation has been meeting the evolving needs of power generating stations, process and manufacturing industries, infrastructure establishments, technology and technological centers and real estate developments with its complete and fully tested product line of Busduct, Bustrunking and associated equipment. We offers in the markets a full range of cast resin insulated busway systems. The concept which was already in use in the sixties in industrial installations is now in the third generation form. Due to the typical characteristics, the system guarantees the integrity of many projects world-wide, providing safe and maintenance free electrical power supplies in both Low Voltage and Medium Voltage installations.

It cover Sandwich Bustrunking, Air Insulated Bustrunking & Lighting Trunking. Bustrunking has lower impedance in comparison to cable and conventional busducts for the same application. Lower impedance means less energy lost during distribution and this translates into cost savings.Plug-in type arrangement at regular intervals or as per customer design provides efficient power distribution. Material and manpower used in busway is lower than cable & conventional busduct. It saves money on raw materials and create less waste by buying pre-engineered lengths of busway. This  system comes with provision of expansions, changes, replacement and reusing.

(G) Cast Resin Low Voltage Betobar

Betobar busbars have been developed as a modern, all-purpose means of efficient and safe transmission of electrical energy. They have been in manufacture for more than thirty-five years. This system complies with all the requirements for current distribution at low and medium voltage.The busbar consists of copper or aluminium conductors, embedded in an enclosure of a fire retardant, self extinguishing and homogeneous insulation mix based on epoxy cast-resin with mineral fillers ensuring high mechanical strength and chemical withstand.Standard types are available for current ratings up to 5000 A and Voltage ratings up to 17.5kV. Systems for higher current ratings or DC applications are possible on request.

The busbar line consists of a number of prefabricated elements. The electrical joining of the conductors is achieved by means of double fish plates and high tensile steel bolts.The junctions and the element ends are overcast with the same insulation mix as used for the elements. In this way an integral insulating enclosure to IP68.IK10 is guaranteed over the full length of the busbar run. Straight junctions and also elbow junctions are available each facilitating installation adjustments of 10-20 mm per standard junction.
