Enhancing Safety with Newage Low Smoke Zero Halogen (LSZH) Cables – The Future of Fire-Safe Wiring
Introduction
As buildings become smarter and more complex, ensuring fire safety and health protection in enclosed spaces has become paramount. Traditional cables, when exposed to fire, release dense smoke and toxic halogen gases, which can obscure escape routes and pose serious health risks to occupants. This is where Low Smoke Zero Halogen (LSZH) cables offer a safer, more sustainable solution.
Newage Cables, a leader in Pakistan’s cable industry since 1956, offers a premium range of LSZH Cables that combine reliable power transmission with unparalleled safety performance. Whether used in high-rise buildings, hospitals, airports, or transportation infrastructure, Newage LSZH Cables protect both lives and assets.
What Are LSZH Cables?
Low Smoke Zero Halogen (LSZH) cables are specially designed to emit:
- Minimal smoke during a fire
- No toxic halogen gases
Unlike standard PVC cables, which contain halogens like chlorine, fluorine, and bromine, LSZH cables use halogen-free materials for insulation and sheathing. This ensures:
- Clearer visibility for emergency evacuations
- Reduced risk of toxic inhalation
- Minimized environmental damage from toxic residues
Key Features of Newage LSZH Cables
1. Halogen-Free Construction
Both the insulation and outer sheath of Newage LSZH cables are made from special thermoplastic compounds that are completely free of chlorine, fluorine, and bromine. This eliminates the risk of corrosive and toxic gas release in case of fire.
2. Low Smoke Emission
In the event of a fire, these cables generate significantly less smoke than conventional cables, maintaining better visibility in escape routes and improving the chances of safe evacuation.
3. Flame Retardant Properties
Newage LSZH cables are designed with enhanced flame retardancy, preventing the spread of fire along the cable path, thus limiting overall fire damage.
4. High Electrical Performance
Despite the focus on safety, Newage LSZH cables do not compromise on electrical performance. They ensure:
- Efficient power transmission
- High insulation resistance
- Excellent dielectric strength
This makes them suitable for both power distribution and signal/data transmission applications.
5. Environmental Benefits
Being free of halogens, LSZH cables are more environmentally friendly, both during their lifecycle and after disposal. They align well with green building standards and sustainability goals.
Applications of Newage LSZH Cables
The superior safety profile of LSZH cables makes them ideal for:
1. Public Buildings & High-Rise Structures
- Hospitals
- Schools
- Airports
- Hotels
- Office Towers
- Shopping Malls
2. Transportation Infrastructure
- Railway Stations
- Metro Systems
- Airports
3. Data Centers & IT Facilities
With high-density cabling, data centers rely on LSZH cables to minimize fire and smoke risk while protecting valuable servers and equipment.
4. Tunnels & Underground Facilities
Enclosed environments like tunnels and underground parking structures benefit from the reduced smoke and toxic gas emissions of LSZH cables.
Compliance with International Standards
Newage LSZH Cables are manufactured in accordance with leading global standards, including:
- IEC 61034 – Measurement of smoke density.
- IEC 60754-1/2 – Determination of halogen acid gas content.
- IEC 60332-1/2 – Flame propagation tests for single and bundled cables.
- BS 6724 – Armored cables with LSZH outer sheath for power distribution.
These standards ensure that Newage LSZH Cables meet the stringent fire safety and environmental requirements for use in critical infrastructure.

Installation Considerations
1. Site Assessment
Before installation, evaluate the fire risk and occupancy density of the project to determine where LSZH cables should be prioritized.
2. Proper Handling
LSZH compounds, while mechanically robust, can be more rigid than PVC. Installers should follow recommended bending radii and avoid excessive pulling forces.
3. Testing & Commissioning
Post-installation, conduct:
- Insulation resistance tests
- Continuity tests
- Smoke and flame propagation checks (where required by building codes)
