DIMENSIONS
What Is SANS 1507-4?
SANS 1507-4 is part of the South African National Standards for power cables. Specifically, Part 4 covers 0.6/1kV Steel Wire Armoured XLPE-PVC cables, which are designed for low-voltage power distribution in fixed installations.
These cables are flame-retardant, robust, and meet stringent safety requirements under IEC 60332-1-2 fire testing standards.
Benefits of Using SANS 1507-4 SWA XLPE-PVC Cables
Durability in Harsh Environments
Steel wire armour resists crushing, impact, and rodent attack.
Ideal for mining, construction, and industrial plants.
Thermal and Electrical Efficiency
XLPE insulation withstands higher temperatures (up to 90°C continuous, 250°C short-circuit).
Lower dielectric losses compared to traditional PVC insulation.
Fire Safety
Flame-retardant sheath minimizes fire hazards, critical in underground mines and factories.
Cost-Effectiveness
Long service life reduces replacement and maintenance costs.
Versatile Applications
Suitable for direct burial, outdoor exposure, and indoor fixed wiring.
Usage Scenarios in South Africa
Mining Industry
Gold Mines (Gauteng & Free State): Powering underground pumps and ventilation systems.
Platinum Mines (North West & Limpopo): Supplying electricity to conveyors and ore crushers.
Coal Mines (Mpumalanga): Used in conveyor belt systems and surface plants.
Heavy Industry
Steel Manufacturing Plants (Vanderbijlpark): Distributing power to furnaces and rolling mills.
Petrochemical Plants (Secunda): Safe power distribution in chemically aggressive environments.
Renewable Energy Projects: Connection between substations and industrial equipment.
Frequently Asked Questions (FAQ)
1. What is the difference between XLPE and PVC insulation?
XLPE has higher temperature tolerance and lower electrical losses than PVC, making it more efficient and durable.
2. Can these cables be used for overhead lines?
No, they are designed for direct burial and fixed installations, not for suspended or flexible applications.
3. Is the armour necessary for all installations?
In harsh environments like mines or outdoor areas, armour is critical for protection. In controlled indoor settings, unarmoured cables may suffice.
4. How long do SANS 1507-4 SWA XLPE-PVC cables last?
With proper installation and maintenance, they can last 30 years or more.
5. Do these cables meet international standards?
Yes, they comply with SANS 1507-4 and are flame-retardant according to IEC 60332-1-2, ensuring international compatibility.
The SANS 1507-4 Steel Wired Armoured XLPE-PVC 0.6/1kV Cable is more than just a power carrier—it is a safety-critical infrastructure component for South Africa’s mining and heavy industries. With its mechanical strength, fire resistance, and electrical reliability, it enables safe, efficient, and long-lasting power distribution under the country’s toughest operating conditions.
As South Africa continues to tackle energy challenges, mining modernization, and safety compliance, these cables will remain a cornerstone of industrial progress.
