6193B Twin & Earth LSZH Cable — 7-Stranded Copper, BASEC & ISO 9001 Certified, IS 201-4 Standard, 300/500V, Low Smoke Zero Halogen for Fire-Safe Wiring
Product Overview
The 6193B Twin & Earth LSZH Cable is a premium fire-retardant domestic wiring solution engineered for safety and reliability, fully compliant with BASEC approval, ISO 9001 quality management standards, and IS 201-4 specifications. Constructed with high-purity stranded copper conductors and Low Smoke Zero Halogen (LSZH) materials, it is designed for surface wiring of sockets, lighting circuits, ring mains, and heavy-duty installations where fire hazards, smoke spread, and toxic fumes pose critical risks to life, property, and sensitive equipment. While originally widely specified in Ireland for fire-risk environments, this cable is increasingly favoured across South Africa—especially in public buildings, commercial complexes, healthcare facilities, educational campuses, and densely populated residential areas—where strict fire safety regulations and human/environmental protection are paramount.
LSZH insulation and sheath emit minimal smoke and no corrosive or halogenated gases when exposed to fire. This is vital in South Africa’s high-density urban centres, underground parking, shopping malls, and public transport hubs, where clear visibility and low toxicity during an emergency allow safer evacuation and reduce damage to valuable electrical and electronic infrastructure—making it a responsible choice for modern infrastructure projects nationwide.
Key Features & Benefits
LSZH Construction: Low Smoke Zero Halogen jacket and insulation drastically reduce smoke density and release zero toxic halogen emissions in case of fire. Protects occupants, minimises corrosion to wiring and devices, and supports compliance with modern fire and building safety codes.
Stranded Copper Conductors: High-quality stranded copper ensures excellent electrical conductivity, flexibility during installation, and resistance to fatigue—outperforming solid conductors in long-term performance and ease of handling on-site.
Certified Quality: BASEC Approved and manufactured under ISO 9001 quality systems, guaranteeing consistent performance, traceability, and adherence to recognised international standards.
Proven Standard Compliance: Fully manufactured to IS 201-4, ensuring consistent dimensions, electrical properties, and fire-safety characteristics you can rely on.
Wide Operating Range: Rated 300/500 V, with working temperatures from -15°C up to +90°C and short-circuit withstand up to 250°C, suitable for South Africa’s varied climate—from coastal humidity to inland heat.
Installation-Friendly: Minimum bending radius of 8× overall diameter allows neat routing in conduits, surface mouldings, and trunking without compromising cable integrity.

Applications & Recommended Use
The 6193B LSZH Twin & Earth cable is purpose‑built for surface wiring in environments where fire safety is a priority. Common uses include:
✅ Residential housing, apartments, and housing developments — especially multi‑storey blocks where escape routes may be limited
✅ Offices, commercial buildings, retail centres, and shopping malls
✅ Hospitals, clinics, schools, universities, and care facilities
✅ Hotels, convention centres, and public venues
✅ Installations near sensitive electronics, data rooms, and critical infrastructure
In South Africa, where building regulations increasingly demand low‑toxicity, low‑smoke materials in public and high‑occupancy spaces, this cable is ideal for new builds, renovations, and retrofits aiming to meet enhanced fire‑safety specifications. The orange outer sheath provides quick, clear identification of fire‑safe wiring, aiding inspection, maintenance, and compliance verification.
