This flexible STA copper LSZH cable is constructed with stranded copper conductors and features steel tape armor (STA) to provide strong resistance against mechanical stress. Its low-smoke, zero-halogen (LSZH) compound makes it a safe choice for confined or populated areas, such as public transit facilities and indoor installations, where both fire safety and cable protection are essential.
Construction and Material
Conductor
Manufactured from stranded plain annealed copper, generally Class 5 flexible, allowing for straightforward bending and simplified handling during installation.
Mechanical Armor
Steel tape armoring (STA) delivers strong defense against physical shock and compression forces.


Sheath/Insulation Material
Low-Smoke Zero-Halogen (LSZH) formulations produce very little smoke and release no poisonous halogens under fire conditions.
Application
Well-suited for a broad range of electrical setups within industrial facilities.
Designed for control and interconnection cabling with conductor sizes starting from 0.5mm² upward.
Especially recommended for use in the machine tool production sector.
Can be employed in turnkey equipment installation and assembly projects.
Also appropriate for deployment in power generation stations.
Applicable to HVAC systems including heating, ventilation, and air-conditioning units.

Benefits
Fire Safety & Environmental Features
Halogen-free composition: Contains no fluorine, chlorine, or bromine, eliminating the release of toxic or acidic fumes in a fire event.
Low smoke emission: Generates minimal dense smoke, preserving visibility to support safe occupant evacuation.
Flame retardancy: Self-extinguishing characteristics prevent flame propagation along the cable length.
Mechanical & Physical Benefits
Steel tape armoring (STA): The "23" code signifies double-layer steel tape reinforcement, delivering strong resistance to crushing forces and mechanical impacts in harsh environments.
Excellent bendability: Constructed with stranded soft copper conductors (Class 5 type), enabling easy bending for confined spaces and rapid installation.
Efficient conductivity: High-purity copper core minimizes power losses and electrical impedance.
Operational Conditions
Voltage Rating: Generally rated at 450/750 V, with certain sub-variants supporting up to 0.6/1 kV.
Number of Cores: Offered in multiple-core arrangements, including 2-core, 3-core, 4-core, and 5-core options.
Thermal Limits: Standard continuous operating temperatures range between 70°C and 90°C.
Fire Safety: Features self-extinguishing properties and meets rigorous flame-retardancy classifications.
Packaging
