3.5 C Stranded Aluminium Cable 3×70 + 35 mm2 PVC Insulation SWA Armed 0.6/1kV 500 m | Red Sea Cables

Technical Specifications for Non-SWA 3×70+35 Cable

The 3.5-core aluminum cable (3×70 + 35) from Red Sea Cables is classified as "Non-SWA 3x70+35 mm Black Cable" in engineering categories. This cable features a stranded circular aluminum conductor (RM) insulated with high-quality PVC material, rated for an operating voltage of 0.6/1 kV. The black outer sheath is a technical feature that enhances UV resistance and prevents degradation caused by direct sun exposure in Saudi Arabia's hot climate, thereby extending the cable's lifespan in outdoor applications.

Cable Ampacity and Power Transmission Efficiency

This is the most critical question for engineers: "How many amps can a 3×70+35 cable carry?" According to standard electrical distribution criteria (IEC 60364-5-52) for outdoor installation at 40°C, a cable with a 70 mm² cross-section can carry a continuous current of approximately 160 amps. This makes it the ideal choice for powering residential units, small industrial motors, or main distribution boards in new buildings.

Key Difference Between SWA and Non-SWA Cables

Many customers confuse 3x70+35 Non-SWA cable with Armored (SWA) cable. The difference lies not just in the cross-section, but in the outer layer. The non-armored cable we offer from Matkal does not include a galvanized steel wire armor (Steel Wire Armor) layer to protect it from mechanical shocks.

• Non-SWA Cable: Ideal for installation inside conduits, ducts, or walls. It is more cost-effective and unaffected by internal humidity.
• SWA Cable: Designed for direct underground burial or exposure to direct friction. Its price is higher due to the steel layer.

Frequently Asked Questions about 3×70+35 Cable

Is black cable better than red cable in the sun? Yes, while black absorbs heat, it is protected by a high-quality PVC layer that resists UV rays, whereas red may fade quickly. Does the size 3×70+35 mean three phases and one neutral? Yes, this is the global standard for three-phase systems.
