With major urban development and industrial growth in 2026, there is strong demand for engineering solutions that combine reliable performance with controlled project cost. TheEl-Hegaz 3-core thermo aluminum cable, size (70 + 35) mm\u00b2<\/strong><\/b>has become a strategic option in the cable market. It is designed as a main power feeder for large residential-building risers, commercial complexes, and major agricultural projects, offering a strong balance between competitive cost and electrical efficiency.<\/p>\n Choosing El-Hegaz means using a product manufactured under defined quality-control requirements. Advanced aluminum alloys are used to address the traditional electrical-resistance challenges of aluminum, making it a practical alternative to copper in main-feeder applications when correctly sized.<\/p>\n El-Hegaz thermo aluminum (70 + 35) mm\u00b2 cable uses an engineered multilayer construction designed for demanding operating conditions:<\/p>\n Main conductors (2 \u00d7 70 mm\u00b2):<\/strong><\/b>High-purity aluminum is heat-treated to improve flexibility and optimize current conduction. The 70 mm\u00b2 size provides sufficient cross-sectional area for large currents up to approximately160 A<\/strong><\/b>under standard conditions, making it suitable for heavy loads when properly engineered.<\/p>\n<\/li>\n Reduced conductor (1 \u00d7 35 mm\u00b2):<\/strong><\/b>This conductor serves as neutral or earth. Using a 35 mm\u00b2 section, half the area of the main phase conductors, can reduce cable weight and cost in balanced systems where the neutral current does not require the same phase capacity, subject to system design and applicable standards.<\/p>\n<\/li>\n<\/ul>\n This cable uses a thermally enhanced PVC insulation system (Thermo-PVC):<\/p>\n Heat resistance:<\/strong><\/b>Designed for efficient continuous operation at temperatures up to70\u00b0C<\/strong><\/b>.<\/p>\n<\/li>\n Chemical stability:<\/strong><\/b>The insulation resists oils, salts, and moisture, helping protect the internal conductors from degradation.<\/p>\n<\/li>\n Mechanical flexibility:<\/strong><\/b>The insulation resists cracking when the cable is bent through confined conduits.<\/p>\n<\/li>\n<\/ul>\n A flexible layer of enhanced plastic surrounds the three cores. Its main function is to maintain a rounded cable shape for easier pulling and provide a protective cushion between insulated conductors and the outer sheath.<\/p>\n A durable black UV-resistant sheath allows the cable to be routed in areas exposed to direct sunlight or open cable paths with reduced risk of long-term sheath drying and deterioration.<\/p>\n This cable can serve as the backbone of risers in buildings exceeding 10 floors, connecting the main panel to sub-distribution boards on each floor and supplying elevators, air-conditioning systems, and lighting loads.<\/p>\n On farms requiring long cable runs, aluminum offers advantages in weight and cost and can be used to feed control panels for deep-well pumps and center-pivot irrigation systems.<\/p>\n For supplying medium machinery and large refrigeration systems in warehouses, the 3-core (70+35) mm\u00b2 cable provides a practical 3-Phase feeder solution with lower initial installation cost.<\/p>\n Why project managers choose El-Hegaz aluminum cable in 2026<\/p>\n Major material savings:<\/strong><\/b>The cable can save approximately60% to 65%<\/strong><\/b>of the budget compared with equivalent copper cable, creating significant savings on large projects.<\/p>\n<\/li>\n Faster installation:<\/strong><\/b>The lower weight of aluminum speeds pulling and installation by up to30%<\/strong><\/b>, helping reduce labor cost.<\/p>\n<\/li>\n Sustainability:<\/strong><\/b>Aluminum is abundant and readily recyclable, aligning with green-building objectives.<\/p>\n<\/li>\n<\/ul>\n For maximum performance from El-Hegaz aluminum (70 + 35) mm\u00b2 cable, follow these requirements:<\/p>\n Use bimetallic lugs:<\/strong><\/b>Never connect aluminum directly to copper. Bimetallic lugs help prevent galvanic corrosion and overheating at connection points.<\/p>\n<\/li>\n Use anti-oxidation compound:<\/strong><\/b>Applying a small amount of suitable joint compound at the connection helps prevent formation of an insulating oxide layer that could impair conductivity.<\/p>\n<\/li>\n Mechanical protection:<\/strong><\/b>When buried or installed in walls, the cable should preferably be placed inside appropriate PVC conduit to protect it from direct impact and mechanical pressure.<\/p>\n<\/li>\n<\/ul>\n All El-Hegaz thermo cables are designed withflame-retardant properties<\/strong><\/b>. In the event of fire, the cable sheath is designed not to propagate flame and to self-extinguish when the flame source is removed, supporting the safety requirements of Egyptian and international building codes applicable in 2026.<\/p>\n Digital marking:<\/strong><\/b>The name \u201cAl Hejaz\u201d and exact size (70 + 35) mm\u00b2 should be clearly printed at regular intervals along the sheath.<\/p>\n<\/li>\n Conductor flexibility:<\/strong><\/b>When the insulation is stripped, the aluminum strands should appear bright silver and bend easily without becoming brittle.<\/p>\n<\/li>\n Sheath quality:<\/strong><\/b>The outer sheath should have uniform thickness and strong scratch resistance.<\/p>\n<\/li>\n<\/ol>\n In conclusion,El-Hegaz 3-core thermo aluminum cable (70 + 35) mm\u00b2<\/strong><\/b>offers a practical balance between technical performance and financial efficiency. It is designed to maintain stable electrical current in large facilities at a competitive total cost, making it a strong option for engineers and contractors in 2026.<\/p>\n","protected":false},"excerpt":{"rendered":" TheEl-Hegaz 3-core thermo aluminum cable, size (70 + 35) mm\u00b2<\/strong><\/b><\/p>\n is an economical engineering solution for users seeking substantial material savings without sacrificing electrical-network reliability.
