H05Z-K and H07Z-K are low smoke and halogen-free industrial wires that comply with EU standards, mainly used in specific industrial scenarios. Their characteristics and applications are as follows:

1.Core Features
(1)Low smoke and halogen-free characteristics
①Low smoke: The amount of smoke generated during combustion is extremely small, which can reduce the impact of smoke on personnel evacuation and equipment visibility in a fire, and lower the risk of suffocation.
②Zero halogen: does not contain halogens (such as chlorine, bromine, etc.), does not release toxic gases (such as hydrogen chloride, hydrogen bromide) when burned, reduces corrosion and damage to human body and equipment, and complies with EU environmental and safety standards (such as EN 50575).
(2)Specifications and Performance
①Model difference:
H05Z-K: The rated voltage is 300/500V, and the cross-sectional area of the conductor is usually small (such as 0.5mm2-6mm2), suitable for low voltage scenarios.
H07Z-K: The rated voltage is 450/750V, and the conductor cross-sectional area is larger (commonly 1.5mm2-16mm2), which can carry higher power and is suitable for medium and high voltage industrial environments.
②Conductor material: mostly copper conductors with good conductivity, some models use tin plated copper to enhance oxidation resistance.
③Insulation layer: Made of halogen-free polyolefin (such as XLPE), it has the characteristics of temperature resistance, wear resistance, and chemical corrosion resistance. The long-term use temperature is usually -40℃ to 150℃ (specific to product standards).
(3)Mechanical and environmental adaptability
①Has a certain degree of flexibility, easy to install and wire.
②UV resistant, oil resistant, suitable for humid, dusty and other industrial environments.
③Compliant with EU RoHS and other environmental directives, meeting the compliance requirements for exporting to the EU market.
2.Main application areas
(1)Industrial equipment wiring
Used for internal circuit connections of industrial machinery such as machine tools, automated production lines, and injection molding machines. Due to its low smoke and halogen-free characteristics, it is safer in enclosed or ventilated workshops.
(2)Architecture and Public Facilities
Suitable for emergency lighting and fire protection system wiring in office buildings, shopping malls, hospitals, and other places. It can reduce the spread of smoke and toxic gases during a fire and buy time for evacuation.
(3)Rail Transit and Ships
As an internal electrical circuit used in enclosed spaces such as subways, high-speed trains, and ships, it meets strict fire prevention and environmental protection requirements.
(4)New energy and electrical equipment
It can be used for internal wiring of new energy facilities such as photovoltaic inverters, energy storage equipment, charging piles, power cabinets, switchgear, as well as power supply lines for large electrical appliances such as air conditioners and elevators.


3.Summary
H05Z-K and H07Z-K are widely used in industrial and public fields with high requirements for fire prevention, health, and compliance, especially in the EU market and projects that comply with international standards, due to their low smoke and halogen-free, safe and environmentally friendly characteristics, and adaptability to various environments.
