3182B 2-Core Round Flexible LSZH Cable – BS EN 50525-3-11, BASEC Approved, 300/500V, Class 2 Fire-Safe Wiring for High-Risk Environments
Product Overview
The 3182B 2-Core Round Flexible LSZH (Low Smoke Zero Halogen) cable is engineered specifically for Class 2 double-insulated lighting and electrical equipment — devices that do not require an earth connection. Designed with safety as its core priority, this cable is ideal for installations where fire risks, dense smoke emission, and toxic fumes pose serious threats to life, property, and critical infrastructure. Whether used in public buildings, commercial interiors, healthcare facilities, transport hubs, or dense residential developments across South Africa, it delivers dependable performance while meeting the strictest fire-safety expectations.
Built on globally recognised standards and certified by leading bodies, this cable balances mechanical flexibility, electrical reliability, and environmental safety — making it a trusted choice for consulting engineers, technical procurement specialists, and electrical contractors who refuse to compromise on compliance or performance.
Key Safety & Construction Advantages
What truly sets the 3182B series apart is its LSZH outer sheath formulation, which contains no halogenated materials. In the event of a fire, it releases very low levels of smoke and no toxic or corrosive halogen gases — a critical feature that preserves visibility, reduces health risks to occupants and emergency responders, and minimises secondary damage to sensitive electronics and equipment.
Fine-stranded copper conductors ensure excellent flexibility, making routing and installation easier even in confined spaces or tight bends.
Round, compact profile simplifies handling, pulling, and termination.
Rated for 300/500 V supply and suitable for continuous operation from -15 °C to 70 °C, withstanding short-circuit temperatures up to 160 °C.
Minimum bending radius: 5× overall diameter — supports neat installation without compromising electrical integrity or lifespan.
Compliance & Certifications — Trusted Quality, Verified Performance
You can specify and procure this cable with full confidence, as it meets rigorous international and European benchmarks:
✅ BASEC Approved — independent assurance of consistent product quality and safety
✅ HAR / CE Marked — compliant with European standards and eligible for use across the European Economic Area
✅ ISO 9001 Manufacture — produced under a certified quality management system for consistent batch-to-batch reliability
✅ BS EN 50525-3-11 — conforms to the European specification for flexible cables with low-smoke halogen-free characteristics
For South African projects, these recognised certifications simplify specification, tender evaluation, and local authority acceptance — helping you meet SANS and National Building Code fire-safety objectives with proven, verifiable documentation.

Recommended Applications
This cable is purpose-built for Class 2 (double-insulated) devices that do not require earthing, including:
Interior and commercial lighting installations
Small and medium household or commercial appliances
Office equipment, IT peripherals, and power supplies
Public spaces, malls, schools, hospitals, and retirement facilities
Hotels, airports, stations, and transport infrastructure
Any installation where fire spread, smoke density, or toxic emissions must be minimised
In South Africa’s climate and building environment — where high temperatures and dense occupancy increase fire risk — choosing LSZH cable is not just a compliance detail; it is a responsible design decision that protects lives, reduces insurance risks, and limits property damage should a fire occur. The 3182B series offers a straightforward, cost-effective way to upgrade fire safety without over-engineering every circuit.
