The Marine Industry

Logstrup (Denmark) is one of the leading European manufacturers of modular switchboard systems. Since 1958 the company has been successfully operating in the world market and for 60 years has developed and improved a significant number of advanced cabinet solutions for electrical panels.

The Logstrup certified design withstands high vibrational loads, which makes it possible to use Logstrup boards on marine vessels, bridges, oil platforms and in other industries with heavy equipment operating conditions.

The modular system of metal structures and bus bars allows to assemble Logstrup switchgears of any configuration in a fixed, removable (RMU), withdrawable (MDU/WDU) design, with a high degree of internal partitioning (up to 4b according to IEC 61439-1,2) for currents up to 8500A, which is a unique offer on the market.

Modular System

• Complete modularity in all 3 axes with a base module of 190mm, which provides the most flexible solution possible

• Width, height and depth as well as sizing and placement of any sub-sections are infinitely variable

• Many space restrictions can be overcome by making angled or back-to-back arrangements.

• The unique corner joint and framework system constructed of 2mm steel profiles, incorporating 5 bends ensures a maximum strength. This makes the system particularly suited for heavy-duty equipment, large busbar systems and demanding operating conditions.

Further benefits of the Logstrup Modular System:

• Minimum downtime

• Re-configuration of units while panel is live

• Ability to interchange different unit types

• Fully Type Tested

• Internal Arc Protection

Structural Parts

• A complete frame bar construction consists of 8 corners (AHC6) and 12 frame bars (AKA).

• The framework may be fitted onto baseframes for floor mounting or wall mounting.

• The base frame is U-shaped and manufactured from 2.5mm high strength, hot-dip galvanized (zinc-coated) steel sheets, available painted or unpainted depending on required anti-corrosion properties

• The profile bend aligns with the framework profiles to ensure maximum stability and support for heavy switchgear

• AKA frame bar structures consist of 2mm steel profiles, each with 5 bending points and coupled together through unique corner joints of aluminium alloy.

This basic construction provides the markets strongest and most reliable structures, which are exceptionally well suited for heavy equipment and demanding environments.

External Cladding

Panels (APA/ALA/AGP) are used to clad the exterior of the framework.

• Type ALA doors are folded hinged covers made from 1.5 or 2 mm sheet steel coated with 60-80 μ Polyester powder paint.

• Type APA panels are folded fixed covers made from 1.5 or 2 mm sheet steel coated with 60-80 μ Polyester powder paint.

• Type AGP plates are flat covers intended to be fitted on the top or rear of enclosures.

• AGP plates are made of mild steel aluzinc coated (aluminium and zinc) and available as standard with or without powder paint coating depending on client requests.

Busbar System

• The Logstrup Busbar System consists of modular components, which allows unlimited variations and ratings

• Three, four and five wire systems can be designed with ease, and ratings up to 8500A are standard, and tested for both temperature rise and short circuit level

• The Busbar System is based on a two bar per phase system, both horizontal and vertical, eliminating time consuming drilling and bending of copper bars

• The Busbar joints are by means of bolts and nuts of 8.8 quality in connection with special spring washers type DIN 6796

• The busbar holder components are manufactured from a high grade polymer which provides a high insulation for the copper bar, good mechanical and thermal strength to meet the stress during a short circuit and ability to withstand variations in temperature during service conditions
