Single-core halogen-free cable, resistant to high temperatures HELUTHERM® 145 1x0.25 mm² green 51078

Single-core halogen-free cable for special applications

This green HELUTHERM® 145 single-core cable with a cross-section of 0.25 mm² combines flexibility, high-temperature resistance, and fire safety. It is an ideal solution for wiring in places where high reliability and minimal release of toxic gases in the event of a fire are required. The cable is characterized by a copper core, which is additionally protected against corrosion by tinning.

Construction and properties

The cable is designed for demanding applications. Its construction is based on:

• Copper core: Made of multi-strand, flexible copper, which ensures good flexibility and easy installation.
• Polyolefin copolymer insulation: Electron-beam cross-linked, guaranteeing high temperature and abrasion resistance. The insulation is halogen-free, which significantly increases safety in the event of a fire – it does not release toxic gases and limits the spread of fire.
• Resistance to external factors: The cable is resistant to UV radiation, ozone and oils, allowing it to be used in various environmental conditions.

This cable also features a high temperature load capacity – it can operate in the range of -35°C to +120°C (flexible) and from -55°C to +145°C (stationary). This makes it ideal for applications exposed to extreme temperatures. However, it should be remembered that under certain conditions, high temperature may allow for a reduction in the cable cross-section without loss of its properties.

Applications and benefits

The HELUTHERM® 145 cable finds wide application in:

• Wiring of lighting fixtures: Safety and temperature resistance are crucial in this type of installation.
• Heating devices: The cable copes well with the high temperatures generated by heating devices.
• Electrical machines (thermal class B): Provides reliable power supply to machines operating in difficult conditions.
• Electrical distribution boards: Ensures safe distribution of electrical energy.
• Surface, concealed and duct installations: The possibility of use in various types of installations increases its versatility.
• Rail vehicles: Possible to use with DC voltage up to 900V (when grounding is used).

It is worth emphasizing that the cable meets safety standards confirmed by Germanischer Lloyd approval and Low Voltage Directive 2014/35/EU. Its halogen-free construction minimizes the risk of poisoning during a fire, enabling safe evacuation of people. Additionally, the cable is characterized by good resistance to mechanical damage and weather conditions, which translates into long life and reliable operation.
