Single-core halogen-free cable H07Z1-K 1G4 mm² yellow-green 18048782

Single-core halogen-free wire – safety and reliability in installations

This halogen-free single-core wire H07Z1-K with a cross-section of 4 mm² in yellow-green color is an ideal solution for applications requiring a high level of fire safety. This wire is designed for installations in buildings with increased risk, where limiting the emission of toxic gases and smoke in the event of a fire is crucial. It will work well both in executive installations and in control cabinets or switchboards.

Construction and properties

The H07Z1-K wire is characterized by a solid construction, based on a multi-strand copper conductor of class 5, providing flexibility and ease of installation. The insulation is made of high-quality polyolefin-based plastic, guaranteeing durability and resistance to external factors. Importantly, the materials used in production do not contain silicone, cadmium, or substances that hinder painting. Thanks to this, the wire meets stringent environmental and safety standards.

• Halogen-free: Compliant with IEC 60754-1, IEC 60754-2, and IEC 60754-3 standards, which means minimal emission of toxic gases during a fire – crucial for protecting health and human life.
• Fire resistance: It has certificates confirming fire resistance in accordance with IEC 60332-1-2, IEC 60332-3-23 (cat. B), and IEC 60332-3-24 (cat. C) standards.
• Low smoke emission: Meets the requirements of IEC 61034-2 standard, which translates to better visibility during evacuation in the event of a fire.
• Reaction to fire class: B2ca according to EN 13501-6 standard – provides an appropriate level of fire safety for various types of buildings.
• Flexibility: Class 5 stranded conductor facilitates routing cables even in tight spaces and ensures comfortable work during installation.
• Chemical resistance: Exhibits good resistance to oils and other chemicals, which increases its durability and reliability in harsh working conditions.

Applications and compliance with standards

The H07Z1-K wire finds wide application in electrical installations of buildings with increased fire risk, such as office buildings, hospitals, schools, airports, or railway stations. It is ideal for cabling control cabinets, switchboards, and automation devices. It meets the requirements of PN-EN 50525-3-31 standard and has numerous approvals (CE, SEC, HAR, BUREAU VERITAS, AENOR and SASO), which confirms its high quality and compliance with applicable regulations. The rated voltage U/U0 is 450/750 V and the maximum conductor temperature is 70°C. The outer diameter of the wire is approximately 4.2 mm.
