How Electrical Cables Are Classified

Electrical cables are described using a combination of conductor type, insulation material, armour (if applicable), and outer sheath. The key parameters that define a cable are:

• Conductor material — copper (Cu) or aluminium (Al)

• Number of cores — single-core, two-core, three-core, four-core, or multi-core

• Cross-sectional area — from 0.5mm² to 630mm² and above

• Insulation — PVC, XLPE, or LSZH

• Armour — SWA (Steel Wire Armoured) or unarmoured

• Voltage rating — typically 450/750V, 0.6/1kV, or 3.3kV to 33kV for medium/high voltage

Types of Electrical Cables and Their Uses

1. Single-Core PVC Cables (House Wiring Cables)

Single-core PVC cables are the most common type used in residential and commercial wiring across Saudi Arabia. They consist of a copper conductor with PVC insulation and are typically pulled through conduits during installation. Standard colour codes are red/brown (live), black/blue (neutral), and green/yellow (earth).

• Applications: Lighting circuits, power sockets, air conditioning connections

• Common sizes: 1.5mm², 2.5mm², 4mm², 6mm², 10mm²

• Standard: IEC 60228 / BS 6004

2. Multi-Core PVC Cables (NYY / NYM Cables)

Multi-core PVC cables contain two or more conductors within a single outer sheath. They are used where a complete circuit (live, neutral, and earth) needs to run as a single cable unit, simplifying installation and cable management.

• Applications: Direct connections to appliances, sub-distribution circuits, outdoor wiring in conduit

• Common configurations: 2-core, 3-core, 4-core in sizes from 1.5mm² to 25mm²

3. Armoured Cables (SWA Cables)

Steel Wire Armoured (SWA) cables have a layer of steel wire between the inner and outer sheaths, providing mechanical protection against physical damage. They are used for direct burial, outdoor runs, and any installation where the cable may be exposed to mechanical stress.

• Applications: Underground power supply cables, outdoor feeder cables, industrial installations

• Standard: IEC 60502 / BS 5467

4. Control Cables

Control cables transmit low-power signals between control panels, instruments, and machinery. They typically have multiple small-gauge cores (from 0.5mm² to 2.5mm²) with PVC or XLPE insulation and an overall screen for noise immunity.

• Applications: PLC wiring, instrumentation, motor control circuits, building management systems (BMS)

• Core count: From 2 cores to 48 cores in a single cable

5. Fire-Resistant Cables (FRC / LSZH Cables)

Fire-resistant cables maintain circuit integrity in the event of a fire for a defined period (typically 30–120 minutes). Low Smoke Zero Halogen (LSZH) cables produce minimal toxic smoke when exposed to flame, making them ideal for enclosed public spaces.

• Applications: Fire alarm systems, emergency lighting, evacuation systems, hospitals, hotels, shopping malls

• Standard: IEC 60331 (fire resistance), IEC 60754 (halogen emission)

6. XLPE Insulated Power Cables

Cross-linked polyethylene (XLPE) insulated cables offer superior thermal performance compared to PVC, operating at higher continuous temperatures (up to 90°C versus 70°C for PVC). They are the standard choice for medium and high-voltage power distribution and are increasingly used for low-voltage applications in demanding environments.

• Applications: Power distribution, substations, industrial feeder cables

• Standard: IEC 60502 (1kV and above)

Copper vs Aluminium Cables — Which Should You Choose?

• Copper cables: Higher conductivity, smaller cross-section for same current, more flexible, easier to terminate — preferred for most residential and commercial applications in Saudi Arabia

• Aluminium cables: Lighter and lower cost per amp-metre, but require larger cross-sections (approximately 1.5x copper), special termination techniques, and anti-oxidant compounds — mainly used for high-voltage overhead lines and some large industrial feeder cables

Expert Tip: For all indoor wiring, distribution boards, and standard LV circuits in Saudi Arabia, copper is the correct choice. Reserve aluminium cables for large industrial or utility applications only, and always use the correct aluminium-compatible terminations.

Cable Insulation Types Explained

• PVC (Polyvinyl Chloride) — Most common, cost-effective, good for standard indoor applications up to 70°C conductor temperature

• XLPE (Cross-Linked Polyethylene) — Higher temperature rating (90°C), better resistance to chemical and environmental stress

• LSZH (Low Smoke Zero Halogen) — Reduced toxicity in fire conditions; mandatory in public buildings, hospitals, and transportation hubs in many specifications

• Rubber — Flexible cables for portable equipment and industrial machinery where flexibility is required

How to Choose the Right Cable Size

Cable sizing in Saudi Arabia follows IEC 60364 guidelines (adopted as SASO 2663). The key factors are:

• Design current — the maximum current the cable will carry

• Installation method — cables in conduit, on trays, or direct burial carry different current capacities

• Ambient temperature — Saudi Arabia's high ambient temperatures require derating factors to be applied

• Voltage drop — the maximum allowable voltage drop along the cable run (typically 3–5% for final circuits)

Quick reference guide for copper PVC cables in standard conduit installations at 40°C ambient temperature:

• 1.5mm² — up to 13A (lighting circuits)

• 2.5mm² — up to 18A (power sockets)

• 4mm² — up to 24A (small AC units, cookers)

• 6mm² — up to 31A (large AC units, electric water heaters)

• 10mm² — up to 42A (sub-main circuits)

• 16mm² — up to 57A (main supply to distribution boards)

Frequently Asked Questions

What is the most commonly used cable in Saudi Arabia for house wiring?

The most common cable for residential wiring in Saudi Arabia is single-core copper PVC-insulated cable, typically 1.5mm² for lighting and 2.5mm² for power sockets, installed in PVC conduit. These cables must comply with SASO and IEC 60228 standards.

What does NYY cable mean?

NYY is the designation for a copper-conductor PVC-insulated, PVC-sheathed multi-core cable (derived from German/IEC nomenclature). It is widely used for underground and protected outdoor installations in Saudi Arabia.

Can I use PVC cables outdoors in Saudi Arabia's hot climate?

PVC cables can be used outdoors if properly installed in UV-resistant conduit or protected from direct sunlight. In Saudi Arabia's extreme heat, XLPE insulated cables are often preferred for exposed or direct-buried outdoor applications as they tolerate higher temperatures and resist UV degradation better.

Why are fire-resistant cables required in some Saudi buildings?

Saudi fire and building codes require fire-resistant (FRC) or LSZH cables for fire safety systems, emergency lighting, and evacuation routes in public buildings, hospitals, hotels, and high-rise structures. This ensures that critical systems remain operational during a fire for the time needed to evacuate occupants safely.

How is cable sold — by the metre or by the drum?

Cables are available both by the metre (for smaller quantities) and in full or cut drums (100m, 200m, 500m, and 1,000m rolls) for larger orders. Most online platforms in Saudi Arabia offer both options, with better pricing per metre available on full drum purchases.
