Single-core halogen-free cable H07Z-K 1G70 mm² yellow-green 51850

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

This yellow-green single-core H07Z-K cable with a cross-section of 70 mm² is an element that will find application in installations requiring increased fire resistance and limitation of toxic gas emissions during a fire. Thanks to the use of halogen-free insulation, this cable minimizes the risk of smoke and corrosive gas formation, which is crucial for the safety of people and equipment.

This cable is particularly recommended for use in public places, industrial facilities and anywhere where high fire safety standards are required. Its flexible, stranded construction makes installation easier and ensures durable connections.

Characteristics and application

The H07Z-K cable is designed to operate at a rated voltage of 450/750V (AC) or 750V (DC) to ground. It can be used both on the surface, under plaster, and in closed cable ducts. It will be suitable for wiring in devices, switchboards and lighting systems. The resistance of the core complies with DIN VDE 0295 class 5, which guarantees efficient current conduction.

Additionally, the cable is characterized by resistance to radiation up to 20 x 10⁶ cJ/kg (up to 80 Mrad), which allows its use in specific environmental conditions. The operating temperature range is from -40°C to +90°C, which ensures reliable operation in various atmospheric conditions.

Advantages and benefits

• Halogen-free insulation: Reduces the emission of toxic gases during a fire, increasing the safety of people near the installation.
• High flexibility: Stranded core construction makes it easier to install and route cables in tight spaces.
• Radiation resistance: Allows the cable to be used in environments exposed to electromagnetic radiation.
• Wide operating temperature range: Ensures reliable operation in various climatic conditions.
• Compliance with standards: The cable meets the requirements of DIN VDE 0285-525-3-41 / DIN EN 50525-3-41 and IEC 60332-1-2 standards regarding fire resistance and low flammability of materials.
• Durable construction: Twisted copper core according to DIN VDE 0295 class 5 ensures long-lasting and reliable operation of the installation.
• Minimum bending radius: Allows easy routing of cables even in hard-to-reach places (≤ 8mm for cables with a diameter below 8mm).
