Design

The Project Scope includes:

  1. Technical support for project participants, including measurements at the target site, reviews, assumptions, guidelines, and inter-branch agreements.

  2. Project Documentation developed to achieve solutions that meet the required technical parameters and operating conditions, while also being the most cost-effective for the investment budget, including:

    • Calculations of basic busbar dimensions for specified temperature limits,
    • Determination of electrical loss levels,
    • Calculation of forces and stresses occurring in busbars during short circuits,
    • Verification of the correctness of material and geometry selection for busbars,
    • Determination of forces transferred to support structures,
    • Calculations of cross-sections of busbars and conductors at grounding points,
    • Drawings of busbar routes and connections to equipment,
    • 3D model of busbar routes and connections to equipment,
    • Drawings of busbar penetrations through building walls,
    • Busbar grounding diagrams,
    • Diagrams and structural details of pressurization systems in the busbar.
  3. Acceptance Documentation, which includes, among others:

    • Drawings, technical descriptions, technical data sheets,
    • Voltage test reports, insulation resistance measurement reports, bolted joint reports,
    • Paint coating measurement reports,
    • Welding Procedure Specifications (WPS), welder certificates,
    • Certificates, attestations, and approvals for applied materials and components,
    • Operation and Maintenance Documentation,
    • Declaration of Conformity,

    • Warranty.


 

Our
Projects

Alstema has manufactured thousands of meters of medium-voltage busducts for dozens of major Power Plants, Thermal Power Plants, Chemical Plants and Refineries in Europe, Asia and Africa. The company's specialty is single-phase busduct (IPB) and three-phase busduct (SPB / NSPB) in round and rectangular designs. In addition, the power distribution cycle includes the company's other projects: power lead cabinets, generator zero cabinets, equipment connections, coolers and other equipment supplied to the world's leading power facility Contractors.
