6943X 3-Core SWA Steel Wire Armoured Cable – BS 5467, BASEC Approved, 600/1000V, Direct Burial, Outdoor & Industrial Power & Control
Product Overview
The 6943X 3-Core Steel Wire Armoured (SWA) range stands as a robust, dependable solution for power distribution and auxiliary control across South Africa’s diverse and often demanding environments. Engineered to BS 5467 standards, fully BASEC approved, and manufactured under ISO 9001 quality management, this cable is purpose-built wherever mechanical stress, impact, or physical damage is a real risk — making it a staple choice for civil engineering, infrastructure, mining perimeter networks, municipal outdoor projects, and industrial installations nationwide.
Designed for 600/1000 V operation, the 6943X series combines high-grade stranded copper conductors with heavy-duty steel wire armour and durable sheathing, delivering outstanding performance whether laid directly underground, clipped to surfaces, routed through cable trays/baskets, or installed in free air. It thrives in the field conditions common across South Africa — from the Western Cape’s coastal winds to inland highveld temperatures and bushveld extremes — with an operating temperature range of -20°C to +90°C, and short-circuit rating certified to 250°C. Its minimum bending radius of 8× overall diameter supports practical installation without compromising mechanical integrity.
Construction & Key Features
Conductors: High-purity stranded copper, offering flexibility alongside low electrical resistance. Performance is precisely measured at 20°C, with resistance values decreasing predictably as conductor size increases — critical for voltage drop calculations over long runs in regional and rural infrastructure work.
Armouring: Galvanised steel wire armour (SWA) provides exceptional crush, impact, and rodent protection — vital for direct-burial and outdoor work in South Africa, where cables often run without extra conduit in road verges, housing developments, and solar farm networks.
Insulation & Sheathing: Engineered for long-term reliability under UV exposure, moisture, and temperature cycling, ensuring consistent performance outdoors and below ground.
Voltage Rating: 600/1000 V — suitable for low-voltage power and control circuits across commercial, industrial, and public-sector projects.
Standards & Compliance: Manufactured to BS 5467, BASEC approved, and backed by ISO 9001 certification — documentation accepted by major South African engineers, procurement bodies, and municipal specification teams.

Typical Applications — Built for South African Conditions
The 6943X SWA range is widely specified across South Africa because it answers the country’s most common installation challenges:
Direct Burial: Ideal for road verges, housing developments, solar and renewable energy sites, and municipal upgrades — the armour removes the need for costly conduit in many standard installations.
Outdoor Power & Lighting: Used extensively for street lighting, park and public-area lighting, perimeter security, and outdoor equipment feeds — UV-stable and weather-resistant year-round.
Industrial & Infrastructure: Suited for factories, plants, infrastructure projects, and mining-support networks — where mechanical protection and long-term reliability are non-negotiable.
Multiple Installation Methods: Approved for direct burial, surface clipping, cable trays, basket systems, and free air — offering flexibility across a single site or project.
Whether you are designing a suburban lighting rollout, laying power cables in a new housing development, or specifying feeders for a commercial or renewable-energy build, the 6943X SWA range delivers proven performance, full traceability, and the certifications accepted across South Africa’s public and private procurement sectors.
Quality & Assurance
Every length is manufactured to BS 5467, independently tested and BASEC approved, with production processes certified to ISO 9001. This means consistent materials, verified performance, and documentation that meets the specification requirements of consulting engineers, municipal supply chains, and major contractors throughout South Africa.
