Whether in construction, transport or for tools and machines - it is impossible to imagine the various branches of industry without steel and therefore, it is considered the most important metal of our time.
In blast furnaces, liquid pig iron is produced from ferrous input materials. It is then processed into crude steel in steel mills. The individual production processes involve extremely high temperatures and flying sparks, and aggressive substances are used. The cables and accessories used for production must be able to withstand these conditions.
But, in order for the required energy to reach the plants in the first place, the power supply around the site must also be established - strict requirements are also placed on these cables. Thus, depending on the application, cable types with special requirements for the insulation of the cores and the sheath are in demand. Whether control cables, data cables or cable glands - HELUKABEL offers the right products for this special industrial environment. And for the cabling from the transformer stations to the factory premises, HELUKABEL also has the right types of underground and medium voltage cables in its broad product portfolio.

Different cables for the steel industry
The MULTITHERM 400-ES, for example, was developed especially for the steel industry. It is equipped with an additional robust braided high-grade steel that protects it from aggressive substances such as casting powder and hydrofluoric acid, and it makes it mechanically highly resilient. The control cable can be used at temperatures up to 400°C. The HELUTHERM 1200/1200-ES can withstand temperatures of up to 1,100°C and therefore has a special core insulation consisting of glass-fibre braiding impregnated with silicone.
In the THERMFLEX 180 EWKF, usable at up to 180°C, both the outer sheath and the core insulation are made of a special silicone rubber material. In addition, the sheath is particularly resistant to abrasion and notching, which makes it far more resilient than a normal silicone cable. A longer life cycle is thus guaranteed. This control cable is also available in shielded and halogen-free versions. In addition, it is resistant to high-molecular oils, plasticisers, diluted acids and alkalis as well as oxidants.
In the field of cable accessories, HELUKABEL offers heat-resistant cable protection conduit systems. For example, the HTP conduit for high temperature protection, which has a high insulation factor due to the silicone jacket containing iron oxide, can be used at 1,090°C for a short time. In addition, the HELU-S-RK-N cable lugs made of nickel can be used for temperatures up to +500°C, and the metal conduit with Agraff profile made of stainless steel can be used for temperatures up to +600°C.
