Steel Industry

Processing steel involves extremely high temperatures with sparks flying and the use of aggressive chemicals. The cables and wires used in the steel industry must reliably withstand these extremely unfavourable conditions.

For these particular industrial environments, HELU has the ideal solution for your application on offer, including control cables, data cables, and compensating cables, as well as cable glands. This includes high-temperature cables and wires with special core insulation and sheathing materials. The vast HELU portfolio also contains earthing and medium-voltage cables especially suited for use in applications ranging from transformer stations to factory sites.

As an example, the HELUTHERM® 400-MULTI-ES was developed specifically for the steel industry. This cable has an additional, robust stainless-steel braiding, which protects it from aggressive substances such as casting powder and hydrofluoric acids, as well as provides it with increased mechanical durability. This high-temperature control cable can withstand temperatures of up to 400°C.

The THERMFLEX 180 EWKF , usable at up to 180°C, has both the outer jacket and the conductor insulation made of a special silicone rubber material. Additionally, the jacket is particularly resistant to abrasion and notching, which makes it far more resilient than a normal silicone cable and guaranteeing a longer life cycle. This control cable is also available in shielded and halogen-free versions. Futhermore, it is resistant to high-molecular oils, plasticizers, diluted acids and alkalis as well as oxidants.

In the field of cable accessories, HELU 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.
