Detailed description

The HELUTHERM® 145 UL/CSA tinned cable from HELUKABEL, with a 2.5mm² cross-section (approx. AWG 14), is a single-conductor wiring solution designed for demanding environments. This cable is certified to UL-Std. 758 (AWM) Style 3578 and CSA-Std. C22.2 No. 210 - AWM I A/B, ensuring compliance with North American standards for industrial and marine applications.

Design and technical performance

This cable features a tinned copper conductor, finely stranded to DIN VDE 0295 Class 5 / IEC 60228 Class 5, offering enhanced corrosion resistance—a critical advantage in marine environments. The conductor insulation is made of cross-linked polyolefin, providing an extended operating temperature range: from -35°C to +120°C when flexibly installed and from -55°C to +145°C when fixed. For UL (AWM) applications, these values are -35°C to +105°C (flexible) and -55°C to +105°C (fixed). It supports a UL (AWM) rated voltage of 600 V and a test voltage of 3000 V.

Durability and certifications

The HELUTHERM® 145 2.5mm² cable stands out for its resistance to UV, ozone, weathering, abrasion, and cuts. It is also non-corrosive when burned (per DIN VDE 0482-754-2 / DIN EN 60754-2 / IEC 60754-2) and halogen-free (per DIN VDE 0482-754-1 / DIN EN 60754-1 / IEC 60754-1), and flame-retardant (CSA FT1). Its compliance with smoke density tests (DIN VDE 0482-1034-1+2 / DIN EN 61034-1+2 / IEC 61034-1+2) and oil resistance (DIN VDE 0473-811-404 / DIN EN 60811-404 / IEC 60811-404, IRM 902 4h at +70°C) makes it suitable for harsh environments. It is DNV GL certified for cross-sections from 0.5 to 50 mm², underscoring its suitability for marine applications. The cable is red (RAL 3000) and has a total weight of approximately 30 kg/km (based on Odoo data of 0.03 kg/m). Precise dimensions (outer diameter, copper weight) for the 2.5mm² cross-section are not specified in the provided documentation.

Specific applications

This cable is suitable for internal wiring of lighting equipment, heating systems, electric machines, switching systems, and distributors in industrial installations, as well as for factory and machinery construction. It can be installed in conduits, under or on plaster, and in closed installation conduits. It is not designed for direct installation in cable trays or open raceways.

« Technical analysis of HELUKABEL HELUTHERM® 145 tinned cable 2.5mm² »

The HELUKABEL HELUTHERM® 145 2.5mm² red cable is a critical component for electrical installations exposed to severe environmental stresses. Its tinned copper core is a major advantage in marine environments, where galvanic corrosion is a common failure factor for bare copper cables. The tin plating ensures increased durability and stable conductivity over time, even in the presence of moisture and saline atmospheres.

The cross-linked polyolefin insulation, with an operating temperature range extended up to +145°C, makes it particularly suitable for engine compartments or electrical panels where heat is a limiting factor for standard PVC cables. Its resistance to UV, ozone, and oils, combined with its halogen-free and flame-retardant properties, ensures superior operational safety and reliability, especially in the event of a fire, where toxic smoke emissions are minimized. These properties clearly distinguish it from non-specialized domestic or industrial cables.

While its installation does not fundamentally differ from a standard electrical cable (cutting, stripping, connection), the choice of connectors compatible with tinned conductors and marine environments is essential to maintain the integrity of the installation. This cable is ideal for powering sensors, navigation instruments, lights, or small auxiliary equipment on sailboats or workboats. Note the restriction regarding direct installation in cable trays, which requires tubular protection or conduit in such configurations. It represents a justified investment for the longevity and safety of onboard or industrial electrical systems.
