El-Hegaz armored copper power cable (3×185 + 95) mm²: armored protection for very high loads

Introduction: Armored cables as a foundation for industrial development in 2026

With major industrial and urban expansion in 2026, electrical reliability is a primary requirement for strategic projects. TheEl-Hegaz armored 3-core copper cable, size (3×185 + 95) mm²is one of the largest and strongest engineering solutions in this range, designed to carry very high currents while withstanding severe mechanical conditions. Its armored construction protects power transmission from heavy pressure, moisture, and chemical exposure in buried and major construction installations.

Choosing El-Hegaz in this size means investing in copper quality and long service life. For very large loads requiring stable current up to400 A, transmission efficiency depends directly on metal purity and armor quality, supported by compliance with relevant Egyptian and international IEC standards.

Chapter One: Structural analysis and advanced technical specifications

El-Hegaz armored (185 + 95) mm² cable uses a complex multilayer construction in which each layer has a defined role in stabilizing power and protecting the conductors:

1. Copper cores

• Main conductors (3×185 mm²):99.9% pure electrolytic red copper is used. The strands are helically arranged to reduce electrical resistance, helping prevent excessive cable temperature and maintain stable voltage delivery to heavy equipment, pumping stations, and major factories.
• Third conductor (3×95 mm²):This conductor serves as neutral or earth. The 95 mm² cross-section applies a reduced-neutral design approach that can maintain safety while reducing total cable weight and final cost and easing pulling over long routes, when appropriate to the system design.

2. Internal insulation

Each copper conductor is insulated with high-density PVC or XLPE, depending on specification, and color-coded for identification. The insulation is designed for elevated operating temperatures and rated voltages up to 0.6/1 kV without dielectric breakdown.

3. Bedding layer

A flexible plastic bedding layer surrounds the cores and acts as a cushion preventing sharp steel armor wires from contacting the internal insulation, protecting conductors against abrasion or concentrated pressure during tight bends in cable rooms.

4. Steel Wire Armor (SWA)

This is the core of the cable’s mechanical strength and consists of strong galvanized-steel wires surrounding the inner layers.

• Mechanical protection:Provides strong protection against cutting and crushing from heavy equipment or trucks passing over the route of a buried cable.
• Environmental protection:Provides a mechanical barrier that helps stop rodents from reaching the copper, which is important in warehouses and desert areas.

5. Outer sheath

The final layer is durable black PVC resistant to ultraviolet radiation, salts, and soil chemicals, making it suitable for direct burial where permitted.

Chapter Two: Applications of 185+95 mm² cable in strategic sectors

1. Heavy factories and transformer stations

Armored 185 mm² cable can serve as a main connection between transformers and main distribution boards (MDB), where large amounts of power must be transferred with minimal thermal loss.

2. Airports, ports, and smart cities

Because infrastructure in these areas is exposed to mechanical loads and persistent moisture, El-Hegaz armored cable helps reduce the risk of sudden underground faults and supports continuity in critical facilities.

3. Water-treatment and seawater-desalination plants

In these environments, the salt-resistant sheath and steel armor provide strong protection against natural corrosion and mechanical vibration generated by large pumps with high starting currents.

Chapter Three: Economic value and long-term feasibility

Investing in El-Hegaz armored cable is a sound long-term financial decision:

• Installation-budget savings:The armored construction can reduce the need for rigid protective conduits; where approved, the cable can be installed in a properly prepared trench with fine-sand bedding and warning tape.
• Reduced energy loss:99.9% pure copper reduces energy lost as heat, helping lower consumption costs and environmental impact.
• Service life exceeding 40 years:The cable is designed for decades of efficient operation with limited routine maintenance, improving asset value and reducing downtime.

Chapter Four: Professional engineering installation guide (best practices)

To achieve maximum performance from El-Hegaz 185+95 mm² armored cable, follow these steps:

• Use metal cable glands:Install dedicated glands that bond the steel armor to the electrical-panel body, providing effective earthing and helping protect people from stray currents.
• Burial depth and warning protection:For truck routes, a burial depth of at least 100 cm is commonly recommended, with protective bricks and colored plastic warning tape approximately 30 cm above the cable, subject to project and local requirements.
• Bending radius:Because of the cable’s weight, maintain a bending radius of at least 12 times the overall cable diameter to protect the armor wires.

Chapter Five: Safety and fire-protection standards

El-Hegaz armored cables are designed withflame-retardant properties. If an electrical fault or external fire occurs, the cable is designed to limit flame propagation along underground routes, providing additional time for automatic fire-protection systems and helping protect people and property.

Chapter Six: How to identify genuine El-Hegaz cable

1. Clear durable marking:The El-Hegaz name, size (3×185 + 95) mm², and production date should be clearly printed on the outer sheath.
2. Uniform steel wires:Armor wires should be bright galvanized steel and evenly arranged under the black sheath without large gaps.
3. Copper color and purity:Genuine copper has a bright pinkish color and should bend without brittleness, indicating low levels of recycled impurities.

Conclusion: El-Hegaz—the power driving the future

In conclusion,El-Hegaz 185 + 95 mm² armored copper cablesets a high standard in power-cable applications by combining strong electrical performance with robust mechanical protection. Choosing this cable supports stable power delivery for decades and makes it suitable for projects focused on safety and sustainability.
