MCT Brattberg

MCT Brattberg's origins date from the mid-18th century. Since 1759, construction work has been taking place in the southern Swedish town of Lyckeåborg, including the production of hammers and other tools. The small company, which focused on supplying tools to workers in the region, would not become the founder of the modular cable duct until the mid-twentieth century.
 
On the river Lyckeby
Already in the 18th century the work of the precursor of MCT Brattberg was carried out from a location right next to a fast-flowing river, the Lyckeby. Where this river today forms a beautiful, natural backdrop for the production halls and office buildings of MCT Brattberg, it was originally of vital importance. The rapids in the river and the waterfall located directly behind the company were a perfect, natural energy source. This energy source was used to drive various small-scale production machines, with which the tools, and later rivets, were manufactured. This energy source is still used today by MCT Brattberg for energy generation, but no longer as the only source.

Origin of MCT Brattberg cable entry

The modern history of MCT Brattberg started in the late 1940s. In the meantime the company was known under the name Lyckeåborgs Bruk. The company has since produced various products, including the well-known rivets at that time.

In the early 1950s a new product was born from this company, an invention of the technical engineer Nils Brattberg. Until then, cables in a ship that had to be routed through a wall or floor were each individually sealed. Sealing each transit hole not only took a lot of time, it also took the necessary space. After all, there had to be enough space between the various feed glands to leave the strength of the steel structure intact. The modular system, invented by Nils Brattberg, was extensively developed and tested by the company. After this it was marketed under the name MCT Brattberg.

Development of the MCT Brattberg system
The MCT Brattberg penetrations were originally developed as multiple, compact and flexible conduits for cables through steel ship walls. Over the years, the system has also been made suitable and tested for piping. Transits were also developed for other environments, such as offshore platforms and submarines, aluminum structures and concrete walls. As a result, the penetrations could also be used in, for example, cellars, tunels, substations, laboratories and power stations.

In addition to being watertight, the newer systems were now also fire-resistant, gas-tight, resistant to pests and electromagnetic radiation. In addition, the systems were tested during explosions (ATEX approval), against long-term pressure (tests at 5, 6 or even 8 bar) and various derived products were brought onto the market. In addition to high-quality penetrations for submarines and subsea installations in the offshore (RGPM, RGPH, LSJ), practical extensions to the system were also introduced such as AddBlocks, U-blocks and more recently HandiBlocks.
