Single-core halogen-free cable, resistant to high temperatures HELUTHERM® 145 1x6 mm² dark blue 51375

Single-core halogen-free cable for applications requiring high thermal resistance

This dark blue HELUTHERM® 145 single-core cable with a cross-section of 6 mm² combines flexibility, safety and reliability. Made of multi-strand, flexible class 5 wire, with insulation made of a different material (details in the technical documentation), it is designed for a wide range of applications where resistance to high temperatures and minimizing fire risk are key. This cable is characterized by a rated voltage U0/U of 300/500 V, and its approximate outer diameter is 5.2 mm.

Safety and operating characteristics

The HELUTHERM® 145 cable is primarily distinguished by its halogen-free construction. This means that in the event of a fire, it does not release toxic gases and fumes, which significantly increases evacuation safety. In addition, thanks to the electron-crosslinked insulating material, the cable is resistant to high temperatures – both during operation (up to +120°C when bent and +145°C when permanently installed), and when in contact with a heat source, e.g. a soldering iron (up to 380°C). This feature allows for reducing the cable cross-section under certain conditions, optimizing installation costs.

Applications and compatibility

This cable finds wide application in various areas:

• Wiring of lighting fixtures: Safety and temperature resistance are crucial in this type of installation.
• Heating devices: Ideal for connecting heaters, furnaces and other heat-generating devices.
• Electrical machines: Thermal class B ensures reliable operation even in harsh conditions.
• Distribution boards: Provides safe and durable connections inside electrical distribution boards.
• Machine and installation construction: The versatility of the cable makes it suitable for various industrial applications.
• Rail vehicles: Can be used at DC voltage up to 900V (in rail vehicles).

The cable meets VDE 0482-332-1-2, DIN EN 60332-1-2 and IEC 60332-1-2 standards regarding fire resistance. It is also compliant with EC Low-Voltage Directive 2006/95/EG and does not contain cadmium or silicone. It can be used in conduit pipes at a rated voltage of up to 1000 V AC or 750 V DC.
