‘ALFADUCT’ busbar trunking system is yet another quality product from ARJ Group! The group’s relentless pursuit to offer high quality end-to-end solutions and products for the construction industry has now one more quality  product to serve the Industry.


  • Easy and quick installation
  • Reduced manpower cost for installation
  • Consumes less space due to the compact sandwich arrangement of bus trunking system
  • Power distribution to many outlets in the premises from a single bus trunking system is possible with tap off arrangement and there by avoids multiple runs of cables saving cost and space
  • Reduced voltage drop
  • Higher KA rating
  • Easy fault identification and rectification. The exact location of fault can be identified easily and replaced in short time which means very low cost of replacement and lesser down time as well
  • Aesthetically pleasing
  • Reliability
  • Safety through IP rating
  • Mechanical protection


The materials that go into the manufacturing of ‘ALFADUCT’ busbar trunking system are sourced from among the best in the industry. They meet specifications that have been stringently defined bearing in mind the criticality of function and SAFETY in operation. The product is designed to comply to the strict International standards of IEC 60439-1&2 and 61439-1&6.

IEC-61439-1&6, IEC-60439-1&2

Specification for low voltage switch gear and control gear assemblies-particular requirement for busbar trunking system.

IS-5578 & IS-11353

Guide for making insulated conductors and Guidance for uniform system of making and identification of conductors and apparatus terminals.The process of manufacturing the busbar trunking system follows IS-2062 and good engineering practice norms.


High quality tin plated oxygen free Copper with 99.99% purity, high quality Aluminum with 99.95% purity ensures highest conductivity and effective utilization of entire cross section area resulting in increased product lifecycle.


Multi layer high quality Class F polyester insulation (155° C) is wrapped over the entire length of the conductor.

Service Conditions

Ambient Temperature: -15°C to 55°C

Relative humidity : 95% or below

Temperature Rise Stability

‘ALFADUCT’ busbar trunking system temperature rise falls much within the limit specified by IEC 61439-1&6 Standards.

Lower voltage drop

Carefully designed and well integrated components engineered in ALFADUCT Sandwich Bus Trunking system offers low impedance and hence lower voltage drop.

High short circuit strength

High quality material selection, both mechanical and electrical coupled with a robust enclosure designed in ‘ALFADUCT’ busbar trunking system can withstand high surge currents during short circuit making the product highly SAFE.
