LSZH (Low Smoke Zero Halogen) Armoured Cables are specially designed for environments where fire safety and low toxicity are critical. Unlike standard PVC sheathed cables, LSZH cables emit minimal smoke and no harmful halogen gases when exposed to fire, reducing health hazards and improving visibility for safe evacuation. These cables feature a steel wire (SWA) or aluminium wire (AWA) armouring for enhanced mechanical protection, making them ideal for high-risk and enclosed installations.
Key Features:
✔ Low Smoke & Zero Halogen – Reduces toxic fumes and smoke in case of fire.
✔ Armoured for Protection – SWA/AWA provides impact resistance and mechanical strength.
✔ Flame Retardant & Fire Resistant – Enhances safety in critical applications.
✔ UV & Moisture Resistant – Suitable for both indoor and outdoor environments.
✔ High Voltage Capacity – Available in low, medium, and high-voltage ratings.
CONSTRUCTION
| Conductors: | Current carrying component of the cable. |
| Material | Plain, stranded, compacted copper as per IEC: 60228 Aluminium, stranded, compacted conductors |
| INSULATION: | The rated voltage level of the cable depends on the dielectric strength and thickness of the insulation. |
| Material | Cross-linked polyethylene (XLPE) Type GP8 as per BS 7655 |
| FILLERS | For providing circular shape to the cable, non-hygroscopic compatible fillers (wherever necessary) are included between laid up cores. |
| BEDDING: | Extruded bedding serves as a bedding for the armour and as a protection for the laid-up cores. |
| Material | LSZH |
| ARMOUR: | Armour provides mechanical protection to the cable. It also serves as an Earth Continuity Conductor (ECC). One layer of round wire is applied helically over the bedding. |
| Material | 1. Galvanised round steel wire (GSWA) – FOR MULTICORE CABLE 2. Aluminium round wire armour (AWA) – FOR SINGLE CORE. |
| OVERSHEATH – FINISH: | LSZH and also Complies with acid gas emission requirements of IEC 60754 Part 1 & Part 2 and also complies with Category C of IEC 60332 – 3. |
