Halogen-Free Cables for Automation Systems and Fire Safety

Modern automation systems require precise data transmission and the highest fire safety standards. In public buildings and locations with high occupancy, it is crucial to use cabling made from halogen-free materials. Today, practically all traditional cables have their halogen-free equivalents.

Material Performance in Extreme Conditions (CPR)

The use of halogen-free materials directly affects the fire safety parameters of a building. According to the current Construction Products Regulation (CPR) classification system, these solutions provide several important advantages:

Limited flame propagation:
These materials are designed to prevent the spread of fire along subsequent sections of the installation.

Low smoke emission:
Low smoke density is essential for carrying out an effective evacuation during a fire.

Corrosion neutrality:
The absence of halogens means that toxic and chemically aggressive gases are not released during combustion, protecting respiratory systems and preventing damage to sensitive electronic equipment.

Transmission of Control and Measurement Signals

For indoor transmission, flexible multi-core cables such as TECHNOTRONIK LIHH are used, as well as their shielded versions with a braided screen made of tinned copper wires – TECHNOTRONIK LIHCH. Shielding protects signals against external electromagnetic interference.

Pair constructions are also available, including TECHNOTRONIK LIHH-P and LIHCH-P.

Smart Buildings and Industrial Networks

EIB Standard:
In installations based on the European Installation Bus (EIB), EIB BUS-H cables are used to connect control devices.

Industrial BUS Networks:
Cables such as TECHNOTRONIK 02YS(St)CH enable transmission speeds of up to 16 Mbit/s.

Data Transmission:
Multi-pair shielded cables RD-H(ST)H Bd with a bundled structure are used for signal transmission up to 10 kHz, providing a low level of crosstalk between pairs.

Interference Reduction:
Cables Li2Y(St)H PiMF use individually shielded pairs, significantly reducing interference between different signals.

Maintaining Functionality of Critical Systems (PH90)

A crucial requirement is to ensure continuous transmission of data and power to systems that must remain operational during a fire and rescue operations.

Alarm and signaling systems:
Cables HTKSH PH90 and HTKSHekw PH90 are dedicated to voice alarm systems and fire protection automation.

Power supply for rescue equipment:
Power cables (N)HXH PH90 and (N)HXCH PH90 supply devices such as fire-fighting water pumps and smoke extraction fans.
