SANS 1507-4 SWA Cable

What is SANS 1507-4 SWA Cable?

SANS 1507-4 SWA Cable is a robust 0.6/1kV low-voltage armoured power cable manufactured to South African National Standards (SANS 1507-4) and international flame retardancy standard IEC 60332-1-2. It is constructed to maintain continuous electrical service in challenging environments where severe mechanical stresses, ground compaction, and underground moisture are prevalent.

Featuring XLPE insulation, an extruded PVC bedding layer, a complete circumferential layer of galvanized steel wire armour (SWA), and a durable PVC outer sheath, this cable provides high dielectric strength and mechanical impact protection. The steel wire armour absorbs substantial physical forces and longitudinal tensile loads, making SANS 1507-4 cables the trusted choice for direct burial in free-draining soil without requiring additional concrete trenching or metal conduit protection.

SANS 1507-4 SWA Cable Construction

• Conductor: High-purity copper conductor (available in 2-core, 3-core, and 4-core configurations ranging from 1.5mm² to 240mm²).
• Insulation: Cross-linked Polyethylene (XLPE), supporting continuous operating temperatures up to +90°C.
• Bedding: Extruded Polyvinyl Chloride (PVC) compound providing a cushioned layer over laid-up cores.
• Armour: Galvanized Steel Wire Armour (SWA), delivering maximum mechanical protection and tensile strength.
• Outer Sheath: Flame-retardant Polyvinyl Chloride (PVC) compound.
• Core Identification: 2-Core: Red, Yellow; 3-Core: Red, Yellow, Blue; 4-Core: Red, Yellow, Blue, Black.
• Sheath Colour: Black with a prominent Red Stripe.

Applications

SANS 1507-4 SWA cables are designed for fixed indoor and outdoor low-voltage power distribution in civil, industrial, commercial, and mining sectors. Thanks to its rigid galvanized steel wire armour, the cable excels in high-stress installations where heavy static crushing and dynamic impacts are common.

Key installation environments include:

• Direct Burial: Safe, direct underground installation in free-draining soil without external ducting.
• Industrial Cable Trays & Racks: Power distribution in manufacturing plants, processing facilities, and warehouses.
• Mining & Infrastructure: Heavy-duty power supply lines across mining sites, sub-stations, and municipal utility networks.
• Outdoor Services: Underground connections for outdoor lighting networks, power feeder lines, and industrial switchgears.

Specifications & Dimensions

SANS 1507-4 SWA cables are available in multiple core options (2, 3, and 4 cores) and cross-sectional areas from 1.5mm² up to 240mm². Minimum bending radius is 6x overall diameter for sizes 1.5mm² to 16mm², and 8x overall diameter for sizes 25mm² and above. Full dimensional tables and current-carrying capacity metrics can be customized according to client project specifications.

Frequently Asked Questions

Q: What is the main benefit of Steel Wire Armour (SWA) in SANS 1507-4 cables?
A: Galvanized Steel Wire Armour (SWA) provides mechanical protection against impact, crushing forces, and mechanical damage, while also giving the cable high tensile strength for direct burial installations.

Q: What is the operating temperature range for SANS 1507-4 XLPE cables?
A: The XLPE insulation allows the continuous conductor operating temperature to reach up to +90°C, with a minimum operating temperature rating of -20°C.

Q: How do you identify the core colors in a SANS 1507-4 cable?
A: Core colors follow standard SANS coding: 2-core (Red, Yellow), 3-core (Red, Yellow, Blue), and 4-core (Red, Yellow, Blue, Black). The outer sheath is black with a distinctive red stripe.

Q: What payment terms does Huadong Cable Group accept for B2B export orders?
A: We accept Telegraphic Transfer (T/T) and Irrevocable Letter of Credit (L/C) at sight for international commercial orders.
