Single-core halogen-free cable, resistant to high temperatures HELUTHERM® 145 1x1.5 mm² dark blue 51333

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

This flexible single-core cable HELUTHERM® 145 is designed for demanding applications where temperature resistance and fire safety are crucial. The cable is characterized by high-quality workmanship and the use of innovative materials, making it a reliable solution for both professional installers and end-users. It is an ideal choice for wiring in places exposed to elevated temperatures or requiring special fire-retardant properties.

Construction and application

The cable is made of multi-wire copper conductors (class 5), which ensures flexibility and ease of installation. The insulation made of cross-linked polyolefin copolymer guarantees high resistance to mechanical, chemical and thermal damage. Thanks to the use of halogen-free technology, the cable does not emit toxic gases and fumes in the event of a fire, which significantly increases evacuation safety. The cable finds wide application in:

• Wiring of lighting fixtures
• Heating devices (e.g., furnaces, heaters)
• Electrical machines (thermal class B)
• Electrical distribution boards
• Construction of machines and installations for, on and in walls
• Applications in rail vehicles (up to 900V DC)

Properties and benefits

The HELUTHERM® 145 cable stands out with a number of features that translate into its exceptional functionality:

• Temperature resistance: Operation in the temperature range from -55°C to +145°C (stationary) and from -35°C to +120°C (flexible) allows for use in extreme conditions.
• Halogen-free: Ensures the safety of people in the event of a fire by the absence of toxic gas emissions. Complies with DIN VDE 0482 part 267, DIN EN 50267-2-1 / IEC 60754-1 and DIN VDE 0472 part 815.
• UV resistance: Enables use outdoors without fear of material degradation.
• High flexibility: Facilitates installation and routing of cables in tight spaces thanks to the construction with flexible multi-wire conductors.
• Abrasion and oil resistance: Ensures durability and reliability in harsh operating conditions.
• Rated voltage: Available rated voltages are 300/500 V and 450/750 V (up to 600/1000 V when laid in conduit).
• Reduced flame propagation: The cable has properties limiting the spread of fire in accordance with DIN VDE 0482-332-1-2 / DIN EN 60332-1-2 / IEC 60332-1-2 and DIN VDE 0482-332-3-22 / DIN EN 60332-3-22 / IEC 60332-3-22.

The conductor cross-section is 1.5 mm², and the outer diameter is approximately 3.1 mm. The cable is available in dark blue (RAL 5002).
