Single-core halogen-free cable, resistant to high temperatures HELUTHERM® 145 1x0.5 mm² purple 51287

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

This purple single-core HELUTHERM® 145 cable, with a cross-section of 0.5 mm², is designed for applications where high temperature resistance and fire safety are critical. Made with multi-strand copper conductors coated with a special polyolefin copolymer, it provides reliable operation in harsh conditions. The cable is characterized by its flexibility and ease of installation.

Construction and properties

The HELUTHERM® 145 cable stands out with its advanced construction, which ensures its unique properties:

• Conductors: Made of copper, multi-strand and flexible (class 5), which facilitates installation and ensures good conductivity.

• Insulation: Electron-beam cross-linked polyolefin copolymer – guarantees high temperature resistance (up to +145°C in stationary operation and +120°C in flexible operation) and self-extinguishing properties.

• Halogen-free: Materials used in production do not contain halogens, which means that in the event of a fire, they do not release toxic gases and fumes, increasing evacuation safety.

• Resistance: The cable is resistant to oils, UV radiation and weather conditions.

• Rated voltage: Suitable for operation at 300/500 V (up to 1 mm²) and 450/750 V and 600/1000 V (when laid in protective conduits for cross-sections from 1.5 mm²).

Applications and benefits

The HELUTHERM® 145 cable finds wide application in various areas:

• Wiring of lighting fixtures: Ideal for use inside lighting fixtures due to its high thermal resistance.

• Heating devices: A safe choice for wiring heating devices.

• Electrical machines (thermal class B): Performs well in electrical machines requiring high operating temperatures.

• Distribution boards: It can be used in electrical distribution boards.

• Building installations: Suitable for the construction of machines and under-, on- and in-wall installations.

• Rail vehicles: Possible application at a DC working voltage of up to 900V.

Thanks to its properties, this cable minimizes the risk of fire and ensures safe operation of electrical installations. Its flexibility makes it easy to install even in hard-to-reach places. In addition, the absence of toxic gas emissions during combustion increases the safety of users in the event of a failure.
