Single-core halogen-free cable H07Z-K 1x2.5 mm² grey, cardboard roll 51783

Single-core halogen-free cable – safety and reliability of installation

This grey single-core cable H07Z-K with a cross-section of 2.5 mm² combines safety and functionality. Made of a stranded copper conductor covered with halogen-free insulation, it provides not only effective energy conduction but also minimizes the risk of toxic gas formation in the event of a fire. This is particularly important in public buildings, industrial facilities, and anywhere where high fire safety standards are required.

Construction and application

The cable is designed for a wide range of applications. Thanks to its flexible stranded wire construction (class 5), it is easy to lay and adapt to various installation configurations. It can be used both on and under plaster, as well as in closed cable ducts. It is ideal for wiring in devices, distribution boards, and lighting systems. The rated voltage of up to 750V (to ground) allows it to be used in many types of electrical installations.

Key features and benefits

• Halogen-free insulation: Limits the emission of smoke and corrosive gases during a fire, increasing the safety of users and facilitating evacuation. Complies with DIN VDE 0285-525-3-41 / DIN EN 50525-3-41.
• Flexible stranded wire: Enables easy installation and adaptation to complex installation layouts.
• Wide operating temperature range: From -40°C to +90°C ensures reliable operation in various environmental conditions.
• Radiation resistance: The cable retains its properties even under the influence of UV radiation (up to 20 x 10⁶ cJ/kg).
• Compliance with standards: The product meets the requirements of the Low Voltage Directive 2014/35/EU (CE marking).
• Conductor resistance: Compliant with DIN VDE 0295 class 5 – guarantees efficient current conduction.
• Minimum bending radius: Facilitates cable laying in tight spaces (≤ 8mm for cables with a diameter below 8mm).
• Insulation resistance: Ensures safe operation of the installation (90°C according to DIN VDE 0282 part 9).

This cable is a solid choice for both professional installers and end customers looking for a safe and reliable solution for their electrical installations. Its technical parameters and compliance with applicable standards guarantee long-term and trouble-free operation.
