Single-core halogen-free cable, resistant to high temperatures HELUTHERM® 145 1x1.5 mm² orange 51331

Single-core halogen-free cable, resistant to high temperatures

This orange HELUTHERM® 145 single-core cable with a cross-section of 1.5 mm² is a reliable solution for demanding electrical installations. It is characterized by high temperature resistance and flame retardant properties, making it an ideal choice for both professionals and end-users who care about safety. The cable is designed for a wide range of applications, from lighting wiring to installations in heating devices and electrical machines.

Construction and application

The cable is made of tinned stranded copper, which ensures flexibility and corrosion resistance. The cross-linked halogen-free polyethylene insulation guarantees safety in the event of a fire – it does not release toxic gases and limits the spread of flames. This means the cable meets strict fire safety standards. Its construction allows it to be used in various conditions, including in conduit (up to 1000 V AC or 750 V DC) and in rail vehicles (up to 900 V DC). The high operating temperature of the cable (up to +145°C in fixed installation) allows for conductor size reduction under certain conditions, optimizing installation costs.

Key features and benefits

• Halogen-free: Ensures the safety of people in the event of a fire by not emitting toxic gases and fumes. This is crucial in public buildings, hospitals or schools.
• High temperature resistance: Enables use in heating devices, lighting fixtures and electrical machines generating heat.
• Flexibility: Multi-wire strand construction of the conductor facilitates installation and routing of cables, especially in tight spaces.
• Resistance to external factors: Exhibits good resistance to abrasion, cuts, UV radiation and ozone – ideal for outdoor use and in harsh environmental conditions.
• Wide range of rated voltages: Suitable for operation at 300/500 V or 450/750 V (depending on the cross-section), which increases its versatility.
• Use in rail transport: Can be used in rail vehicles at direct current up to 900V.
• Minimum bending radius: Facilitates cable routing even in tight spaces – the bending radius is 12.5 times the outer diameter of the conductor during dynamic laying.
