ARE4H5E Cable

What is ARE4H5E Cable?

The ARE4H5E Cable is a single-conductor aluminium medium-voltage distribution power cable engineered in accordance with IEC 60502-2 and generally conforming to HD 620 10 I1 specifications. Rated for nominal operating voltages of 12/20 (24)kV and 18/30 (36)kV, it is designed for utility power distribution, transmission substation feeders, industrial facilities, and renewable energy collector grids such as wind power generation plants.

The cable features a Class 2 compacted circular stranded aluminium conductor insulated with high-grade dry-cured XLPE compound (DIX 8) bonded between extruded semi-conductive screens. Protected by a semiconductive watertight tape and a longitudinally applied aluminium tape metallic screen beneath a rugged red MDPE (DPM 2) outer sheath, ARE4H5E delivers halogen-free performance (IEC 60754), radial water blocking, and mechanical abrasion resistance across subterranean conduits, open-air racks, and protected direct-burial trenches.

ARE4H5E Cable Construction

• Conductor: Class 2 compacted stranded circular aluminium conductor.
• Conductor Screen: Extruded semi-conductive XLPE compound for electrical stress control.
• Insulation: Cross-Linked Polyethylene (XLPE) compound (DIX 8) providing dielectric strength and continuous thermal endurance up to 90°C.
• Insulation Screen: Extruded semi-conductive XLPE compound bonded to the primary dielectric layer.
• Protective Layer: Semiconductive watertight tape applied over the insulation screen to prevent moisture penetration.
• Metallic Screen: Longitudinally applied aluminium tape providing electrostatic screening and radial moisture barrier protection.
• Outer Sheath: Medium Density Polyethylene (MDPE) compound (DPM 2) delivering environmental, abrasion, and tear resistance.
• Outer Sheath Colour: Red.

Applications

ARE4H5E medium-voltage cables are engineered for primary electrical energy distribution across diverse civil, utility, and renewable energy installations:

• Wind Power Plants: Medium-voltage power collection circuits and collector networks linking wind turbine step-up transformers to substation switchgear.
• Underground Utility Channels: Primary distribution runs routed through concrete cable galleries, raceways, and sub-station basement trenches.
• Underground Pipe & Duct Systems: Pulled through subterranean PVC/PE duct banks and conduits subject to pulling friction and moisture.
• Protected Direct Underground Burial: Soil trench installation with appropriate backfilling and mechanical cover tiles or slabs.
• Open Air & Industrial Cable Trays: External indoor/outdoor perimeter routes and ladder-rack distribution across industrial facilities.

Specifications & Dimensions

Huadong Cable Group manufactures single-core ARE4H5E cables across 12/20 (24)kV and 18/30 (36)kV ratings in cross-sectional areas from 50mm² up to 630mm² (including 50, 70, 95, 120, 150, 185, 240, 300, 400, 500, and 630mm²). In the 12/20kV class, the cable utilizes a 4.9mm nominal XLPE insulation thickness (minimum 4.31mm), with overall outer diameters ranging from 27.32mm to 50.52mm and unit weights from 607 kg/km to 2,785 kg/km. In the 18/30kV class, it incorporates a 7.25mm nominal XLPE insulation thickness (minimum 6.5mm), with overall diameters spanning 32.02mm to 55.22mm and weights from 767 kg/km to 3,084 kg/km. Operating at a continuous conductor temperature of 90°C, minimum installation temperature of -25°C, and short-circuit thermal limit of 250°C (5 seconds), conductor DC resistance at 20°C ranges from 0.641 Ω/km (50mm²) down to 0.0469 Ω/km (630mm²). Trefoil-formation current carrying capacities reach up to 914A in air (30°C) and 610A in ground (20°C, depth 0.8m), with all dimensional tolerances strictly conforming to IEC 60502-2 and HD 620.

Frequently Asked Questions

Q: What is the structural difference between ARE4H1R and ARE4H5E cables?
A: ARE4H1R uses a metallic screen made of copper wires and tape with a red PVC (ST2) outer sheath, whereas ARE4H5E incorporates a longitudinally applied aluminium tape metallic screen with a halogen-free red MDPE (DPM 2) outer jacket, offering a lighter construction and enhanced moisture barrier properties.

Q: How does the longitudinally applied aluminium tape function in ARE4H5E?
A: The aluminium tape acts as both an electrical metallic screen to conduct fault currents and a radial moisture barrier that prevents water vapor from penetrating through the sheath into the XLPE insulation.

Q: Can ARE4H5E cable be installed in open air and direct burial?
A: Yes, the cable is rated for open air installation as well as underground channels, duct pipes, and direct underground burial provided adequate mechanical protection is implemented.

Q: What commercial payment terms does Huadong Cable accept for international project orders?
A: We accept standard international commercial payment terms, primarily Telegraphic Transfer (T/T, with 30% advance deposit and 70% against shipping documents) and 100% Irrevocable Letter of Credit (L/C) at sight.
