Halogen-free control and power cable, shielded HELUCONTROL® JZ-520-HMH-C LS0H GREY 4G1,5 mm² grey, black numbered cores acc. to DIN VDE 0293-334 11008793

Shielded control cable – safety and reliability in installations

This flexible control cable JZ-520 HMH-C LS0H 4G1.5, shielded, is a solution designed for demanding applications where safety and reliability are key. This cable, classified as B2ca, is ideal for public buildings and industrial installations. Its construction provides high fire resistance and limits the emission of toxic gases in the event of a fire.

Construction and properties

The cable is made of stranded copper conductors, which provides high flexibility and resistance to material fatigue during frequent bending. The conductors are insulated with a halogen-free polymer mixture TI7, which further increases safety. A braid of copper wires with a coverage density of approx. 85% effectively protects against electromagnetic interference (EMC), ensuring stable signal transmission. The outer jacket made of halogen-free material M1 guarantees resistance to weather conditions and mechanical damage.

• Un-tinned, flexible copper conductors class 5.
• Insulation made of halogen-free polymer mixture TI7.
• Screen in the form of a braid of copper wires (approx. 85% coverage).
• Jacket made of halogen-free material M1 (grey RAL 7001 color).
• Metered cable for convenient dispensing and installation.
• Fire reaction class B2ca-s1a, d0, a1 according to EN 50575 standard – high level of fire safety.

Application and benefits

JZ-520 HMH-C LS0H 4G1.5 cable is used as a control cable in buildings of the People Hazard (ZL) character, such as office buildings, hospitals, schools or airports. It will also be useful in industrial installations, machines and air conditioning systems. Thanks to its properties, it is perfectly suited for applications requiring high fire resistance and limited smoke and toxic gas emissions in the event of a fire.

• Safety: Halogen-free construction minimizes the risk of toxic gas formation during a fire, protecting people and sensitive electronics.
• Reliability: Shielding ensures stable signal transmission and minimizes electromagnetic interference.
• Flexibility: Stranded conductors make it easy to install and lay the cable in tight spaces.
• Durability: Resistant materials ensure a long service life of the cable even in difficult operating conditions.
• Compliance with standards: Meets the requirements of the Low Voltage Directive 2014/35/EU and European standards regarding fire safety.

Additionally, remember to optimize electromagnetic compatibility (EMC) by ensuring two-sided contact of the copper braid with the terminals (e.g. EMC cable glands).
