Single-core halogen-free cable, resistant to high temperatures HELUTHERM® 145 1x6 mm² grey 51370

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

This grey, single-core HELUTHERM® 145 cable with a cross-section of 6 mm² combines flexibility and safety. Made with stranded copper, it has cross-linked polyethylene insulation, ensuring high resistance to temperature and external factors. The cable is halogen-free, minimizing the risk of toxic gas formation in the event of a fire – crucial for the safety of users and installers.

Construction and application

This cable is designed for a wide range of applications, both in fixed and flexible installations. It is ideal for wiring lighting fixtures, heating devices, electrical machines, and in the construction of switchboards. Thanks to its high thermal resistance (up to +145°C in fixed installations), it can be used in places exposed to elevated temperatures. The possibility of use in conduit increases its versatility, allowing operation at voltages up to 1000 V AC or 750 V DC. In rail vehicles, a DC load of up to 900V is permissible.

Safety and properties

• Halogen-free: a key feature ensuring safety in the event of a fire – the absence of toxic gas emissions facilitates evacuation.
• High temperature resistance: allows the cable to be used in harsh thermal conditions, and potentially reduce cable cross-sections in some applications.
• Flexibility: the construction with a multi-wire class 5 core ensures easy installation and adaptation to various installation layouts.
• Mechanical strength: the cross-linked polyethylene insulation is characterized by good resistance to abrasion and mechanical damage.
• Chemical resistance: the cable is resistant to oils and atmospheric factors, increasing its durability and reliability.
• Rated voltage: U0/U 300/500 V up to 1 mm² and U0/U 450/750 V from 1.5 mm². For fixed installations, a voltage of U0/U 600/1000 V is permissible from 1.5 mm².
• Approximate outer diameter: 5.2 mm – important information when planning cable routes and selecting mounting accessories.
