All Aluminum Conductor 200mm2 AAC 19/3.66 Stranded Bare Cable for Rural Distribution Networks

This 200 mm² AAC conductor is stranded from nineteen hard drawn 1350 aluminium wires of 3.66 mm, giving a nominal area of 200 mm², an overall diameter of 18.3 mm, a calculated weight of 549.7 kg/km and a rated strength of 32.00 kN. It sits in the working middle of the all aluminium range: heavy enough to carry a village feeder or a small industrial spur over normal pole spans, light enough to be installed on standard wooden or concrete poles without a tower design review. In rural distribution it is commonly used for the three-phase backbone between a distribution transformer and the last cluster of service connections, for spur lines into farms and pumping stations, and for networks that are extended in stages as load grows.

Rural distribution lines are long, lightly loaded and difficult to maintain, and the 200 mm² AAC answers all three constraints. A D.C. resistance of 0.1439 Ω/km at 20 °C keeps voltage drop inside the statutory band at the far end of a feeder, so transformers can be spaced further apart. The single-material build removes the steel core and its galvanising, which is the part that fails first on inland routes exposed to humidity, fertiliser dust and seasonal flooding; the conductor surface simply oxidises and stays serviceable. Mechanically, the 19-wire stranding and 32.00 kN rated strength give a predictable sag that line crews can set by stringing table without survey rework, and the conductor tolerates the small vibrations and galloping that short, stiff rural spans produce. The weight of 549.7 kg/km also keeps pole loading modest, which matters where poles are locally sourced and cross-arms are simple.

Production starts with 1350 grade aluminium rod, drawn to 3.66 mm under a schedule that delivers the H19 temper evenly along the coil, because uneven temper shows up later as inconsistent sag between adjacent spans. Every wire is checked for diameter and for surface condition before stranding; wire with laps, slivers, deep die marks or burrs is scrapped rather than used, as these defects concentrate stress under vibration and collect moisture and pollution. The nineteen wires are then stranded concentrically with controlled lay length and layer tension, so the conductor emerges round and the layers remain closed when the crew cuts it on site. After stranding, each length is inspected and tested for overall diameter, lay, weight and D.C. resistance, and a tensile test on the completed conductor verifies the rated strength. The plant operates to ISO 9001:2015 and ISO 14001 with 100 % inspection before dispatch; OEM marking, drum printing and private labelling are available for distributor stock.

• 19/3.66 mm stranding: hard drawn 1350 aluminium wires, concentrically stranded and tightly closed
• Rated strength 32.00 kN: stable sag on standard rural pole spans without special tower design
• D.C. resistance 0.1439 Ω/km: voltage drop controlled on long feeders with widely spaced transformers
• 549.7 kg/km weight: modest pole loading for locally sourced poles and simple cross-arms
• No steel core: no galvanising to fail, no bimetal corrosion in humid or flooded ground
• All aluminium jointing: compression sleeves, clamps and connectors are rated for one metal only

Rural distribution backbone and spur lines, farm and pumping station supplies, village electrification schemes, small industrial estate feeds, and staged network extensions where load grows over time. Confirm the size against calculated sag, wind and ice loading, and the fault level of the upstream transformer before ordering.

Supplied on wooden drums with flange marking showing model, size, stranding, length, standard and batch. Each shipment carries a packing list and inspection record, and third-party inspection or type test reports can be organised when the contract requires them.
