El-Hegaz armored 3-core aluminum cable (185 + 95) mm²: heavy-duty armored capacity for 2026

Introduction: High-capacity armored cables in the 2026 infrastructure vision

With the major industrial and construction transformation underway in 2026, electrical reliability and mechanical safety have become fundamental to sustainable national projects and large industrial facilities. TheEl-Hegaz armored 3-core aluminum cable, size (185 + 95) mm²is a high-capacity engineering solution combining strong mechanical protection with the economic advantages of high-purity aluminum. It is designed as a main feeder in demanding environments, providing robust protection against mechanical damage while maintaining efficient power transmission for large loads exceeding330 A.

Choosing El-Hegaz in the armored-cable category reflects confidence in manufacturing designed to meet the unified Egyptian code and relevant international IEC standards. For supplying major factories, shopping centers, and pumping stations, the 185+95 mm² size offers strategic power capacity and can provide material savings of up to 70% compared with conventional copper cable when correctly engineered.

Chapter One: Structural analysis and protective cable layers

El-Hegaz armored (185 + 95) mm² cable uses a reinforced multilayer construction designed to provide strong underground protection in demanding weather conditions:

1. Aluminum conductors (high-capacity core)

• Main conductors (2 × 185 mm²):High-purity aluminum alloy (EC Grade 1350) with purity above 99.7% is used. The conductors undergo controlled heat treatment to reduce electrical resistance to technically low levels. The 185 mm² cross-section provides substantial capacity for large loads with reduced thermal loss, helping lower overall energy loss and cable heating.

• Reduced conductor (1 × 95 mm²):This conductor serves as neutral or earth. Using a 95 mm² cross-section can reduce cable weight and cost because neutral current in suitable balanced systems may not require the same cross-sectional area as the phases. This also reduces the overall cable diameter and can simplify pulling and installation, subject to the project design.

2. Enhanced PVC insulation (thermo-resistant insulation)

Each of the three conductors is covered with heat-treated PVC formulated to provide:

• Continuous operating-temperature capability up to70°C.

• Chemical stability that helps prevent deterioration caused by moisture or salts in soil.

• Mechanical flexibility that helps prevent insulation cracking during large bends at installation.

3. Inner bedding layer

A flexible layer of enhanced polymer surrounds the three insulated cores. It forms a protective cushion that prevents the metal steel armor from contacting the inner conductor insulation. It also maintains a uniform round cable shape for secure cable-gland installation and helps prevent dust or moisture ingress.

4. Steel Wire Armor (SWA)

This is the cable’s key mechanical-protection feature. It consists of galvanized-steel wires helically surrounding the cable and provides:

• Heavy-duty mechanical protection:Against breakage, cutting, accidental excavation by heavy machinery, and crushing by large trucks at construction sites.

• Additional earthing path:Improves system safety by providing a low-resistance path capable of carrying high earth-fault currents when correctly bonded.

• Rodent resistance:The steel armor forms a strong barrier against rodent penetration in desert areas and new developments.

5. Outer protective jacket

A highly durable black sheath resistant to UV radiation, moisture, and soil chemicals, making the cable suitable for long-term direct burial when installation requirements are satisfied.

Chapter Two: Applications of the (185 + 95) mm² cable in major sectors in 2026

1. Supplying main distribution boards (MDB)

This size is a major feeder option for connecting high-capacity transformers to main distribution boards in factories, large shopping centers, and airports, supplying centralized lighting, large HVAC systems, and heavy motors.

2. Industrial areas and national projects

In environments with heavy equipment traffic, the armored construction helps protect electrical circuits from continuous mechanical pressure on surfaces above cable routes, reducing the risk of costly factory downtime.

3. Pumping and water-treatment stations

With strong moisture resistance and direct-burial capability, El-Hegaz 185+95 mm² cable can be used to supply large suction and lifting pumps that require highly stable power and protection against environmental corrosion.

Chapter Three: Economic feasibility and sustainability in 2026

Why is El-Hegaz armored aluminum cable a leading consultant choice in 2026?

• Strategic material savings:The cable can save approximately70%compared with the cost of equivalent copper cables, freeing significant budget for other parts of the project without compromising the required electrical design.

• Lower infrastructure cost:Where direct burial is permitted, armored cable can reduce or eliminate the need for expensive protective PVC conduits and the additional labor required to install them.

• Faster completion:Aluminum’s lower weight compared with copper allows crews to pull the cable over long distances with less effort and at higher speed, reducing project execution time.

Chapter Four: Engineering installation guide for high-capacity loads

For maximum performance, strict engineering practices should be followed when installing El-Hegaz 185+95 mm² cable:

• Use armor cable glands:Terminate the cable with glands designed for armored cable to securely grip the steel armor and bond it to the panel’s main earthing system.

• Use bimetallic lugs:Bimetallic copper/aluminum lugs are essential when connecting aluminum conductors to copper breaker terminals to prevent galvanic corrosion, overheating at contact points, and panel-fire risk.

• Burial depth and warning protection:In traffic areas, a burial depth of at least 100–120 cm is commonly recommended, with fine-sand bedding below and above the cable and a visible plastic warning tape marking the presence of electrical cables, subject to project and local-code requirements.

Chapter Five: Safety and international protection standards

El-Hegaz armored cables are designed to comply with relevant Egyptian (ES) and international (IEC) standards. The outer insulation featuresflame-retardant properties, helping make it suitable for busy critical facilities in 2026 by limiting flame propagation in emergency conditions.

Chapter Six: How to verify genuine El-Hegaz cable

1. Clear digital marking:The name “Al Hejaz” and exact size (185 + 95) mm² should be clearly and regularly printed along the cable.

2. Uniform armor:The galvanized-steel wires should surround the cable completely with consistent density and no large gaps.

3. Quality-assurance certificate:Always request the factory test certificate confirming that the cable meets the specified 2026 project requirements.

Conclusion: El-Hegaz—the armored strength that builds the future

In conclusion,El-Hegaz armored 3-core aluminum cable (185 + 95) mm²is a high-capacity armored power-transmission solution for very large loads in 2026. It combines competitive material cost with robust steel armor, making it a strong investment for sustainable infrastructure.
