GDA 63 – 2500 A

Graziadio GDA busbars with aluminum conductors, available from 63 A to 2500 A, are ideal for use in factories, factories and many other sectors where it is necessary to provide junction outputs, or where flexibility is required in moving machinery without additional costs. installation. Quick and easy compared to the cable system. The GDA bus duct lines can also be installed vertically: the bars are installed through the floor and, for each floor, there is a branch that feeds the panels. The range of tap off boxes starts from 32 up to 1250 A.

  • Monoblock junction
  • Configurations: 4P + PE; 5P + PE
  • Length of the elements: 4 m and any customized length
  • Distance between plug-in points: 1 m / 0.5 m
  • Use in same moment of opposite side plug-in points
  • Tap off boxes: 32 to 1250 A (light, robust and design)
  • Degree of protection: up to IP55
  • Live parts not accessibles
  • Advantages: corrosion resistance; fast and easy to assembly; high thermal dissipation; lightness; reusable and recyclable, high heat dissipation that allows installation in environments with little air circulation.

    K SERIES 800-5000 A

  • Graziadio & C. K SERIES busbars are available from 800 A up to 5000 A and are appropriated for power transportation and distribution in commercial and industrial buildings even in restricted spaces. This Busbar trunking system is compact and can be installed edgewise, flat or vertically. K SERIES busbars can be supplied with aluminum or copper conductors. The conductors are insulated with suitably pre-shaped, self-extinguishing V TM-0 halogen free polyester double film, in thermal class B complying with EN 60695-2 -10. The standard protection degree is IP42 and can be increased up to IP55. The aluminum housing provides protection and mechanical seal of the conductors. The matte black painting increase the heat dissipation along the line. The standard length of the straight element is 4 meters to minimize the number of joints and in consequence the installation time. On request can be supplied any other custom size.

  • Straight elements length 4 m, the customized lengths are available on request
  • Monobloc joint with predefined breaking
  • Distance between plug-in points 1 m
  • Tap off boxes from 32 up to 1250 A: plug-in type 32 – 400 A GDA series, bolted type 630 – 1250 A dedicated for K SERIES
  • Energized line’s live parts are not accessibles.
  • High resistance to short circuit
  • Protection degree up to IP55 (IP65 on request)
  • Custom made elements T, Z.
  • Fire barriers with fire resistance up to 120 minutes
  • Accessories to connect to transformers, generators, electric panels
  • Advantages: corrosion resistance, reliable monobloc joint, high thermal dissipation, lightness, multiple customizations, reusable and recyclable.
  • Rating of Bus-bar: 800A to 10,000A

    ISOLSBARRA 630 – 6300 A

    ISOLSBARRA is a high power, prefabricated busbar system with insulated conductors, from 630 A to 6300 A, for both indoor and outdoor use with a protection degree ranging from IP42 – IP68. Like K series and GDA power busbar, Isolbarra can be supplied with either copper or aluminium conductors. The conductors are individually insulated and protected by a strong PVC sheath, but this sheathing can be changed to fibreglass on request. Isolsbarra is supplied in standard 4m lengths in order to minimise the number of joints and therefore the installation time. We can supply any lenght on request.

  • Execution: 3P + PE; 4P + PE; 5P + PE; N = 50% -100% -200%
  • Item Length: 4 m and any customized length
  • Distance between plug-in points: 1 m / 0.5 m
  • Tap off boxes: from 100 to 1250 A (lightweight, robust and design)
  • Types of insulation: Fiberglass (Class H – 180 ° C), PVC (Class Y), Air
  • Live parts not accessible with line in operation
  • Protection degree: from IP30 to IP66; IP68
  • Possibility of connecting elements with different degrees of IP at any time
  • Types of Insulation: Fiberglass (H Class – 180°C), PVC (Y Class), Air
  • High short-circuit resistance
  • Possibility to create bespoke items, T, Z.
  • Fire barriers with fire resistance up to 3 hours
