Product Overview
The LSZH 4 Core SWA Armoured Copper Tape Screened Cable is a high-performance low voltage power and control cable rated at 0.6/1kV. It combines steel wire armour (SWA) for superior mechanical protection, copper tape screening for electromagnetic interference (EMI) shielding, and a low smoke zero halogen (LSZH) outer sheath for maximum fire safety.
This cable is specifically designed for installations where human life, sensitive equipment, and fire regulations are critical – such as tunnels, underground railways, airports, high-rise buildings, hospitals, data centers, and industrial plants.
Key Features
-
LSZH Outer Sheath – Emits minimal smoke and no toxic halogen gases when exposed to fire, ensuring safe evacuation and protecting equipment.
-
Steel Wire Armour (SWA) – Provides excellent mechanical protection against impact, rodent attack, and digging, making it suitable for direct burial or exposed runs.
-
Copper Tape Screening – Offers effective shielding against electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring signal integrity for control and instrumentation circuits.
-
4 Core Construction – Ideal for 3-phase + neutral power distribution or control applications.
-
XLPE Insulation – High thermal rating (up to 90°C continuously, 250°C under short circuit) and superior dielectric strength compared to PVC.
-
0.6/1kV Voltage Rating – Compatible with most low voltage power distribution systems worldwide.

Why Choose LSZH + SWA + Copper Tape Screen?
LSZH Outer Sheath
In a fire, standard PVC cables release dense black smoke and toxic hydrogen chloride gas. LSZH sheath produces minimal smoke and no halogen gases – saving lives and protecting sensitive electronics.
Steel Wire Armour (SWA)
The galvanized steel wire layer protects the cable from mechanical impact, crushing, and rodent attack. It also provides a continuous earth path.
Copper Tape Screen
The overlapped copper tape screen rejects electrical noise from nearby motors, variable frequency drives, or power cables – essential for control and instrumentation circuits.
XLPE Insulation
XLPE offers higher current ratings, better overload tolerance, and longer service life than PVC. It also withstands higher short-circuit temperatures.

Frequently Asked Questions (FAQ)
Q: What does LSZH stand for?
A: LSZH stands for Low Smoke Zero Halogen. It means the cable sheath emits minimal smoke and no toxic halogen gases when exposed to fire, making it safe for use in enclosed public spaces.
Q: What is the purpose of copper tape screening?
A: Copper tape screening provides electromagnetic interference (EMI) shielding, protecting sensitive control signals from external electrical noise generated by motors, VFDs, or adjacent power cables.
Q: Where is 4 core SWA LSZH cable typically used?
A: This cable is commonly used in tunnels, underground railways, airports, high-rise buildings, hospitals, data centers, and industrial plants where fire safety, mechanical protection, and EMI shielding are critical.
Q: What voltage is this cable rated for?
A: The LSZH 4 Core SWA Armoured Copper Tape Screened Cable is rated at 600/1000V (0.6/1kV) for low voltage power distribution.
Q: Can I use this cable outdoors or underground?
A: Yes, the steel wire armour (SWA) provides excellent mechanical protection, making it suitable for direct burial, outdoor installation, and exposed runs. However, for direct sunlight exposure, please confirm UV resistance of the LSZH sheath.
Q: What is the minimum order quantity (MOQ)?
A: MOQ depends on the conductor size.
