1033.5 MCM ORTOLAN ACSR Conductor Cable
The Ortolan ACSR Conductor Cable is a high-capacity overhead conductor designed for efficient power transmission. Named "Ortolan" for its 1033.5 MCM size with 45/7 stranding (45 aluminum wires around 7 steel cores), it combines lightweight aluminum for conductivity with a galvanized steel core for tensile strength. Compliant with ASTM B230, B232, and ICEA standards, this cable offers a breaking load of approximately 32,300 lbs and a current rating up to 1000 amps at 75°C in overhead applications. The aluminum 1350-H19 provides excellent corrosion resistance and low electrical resistance (0.0166 Ω/1000ft at 20°C), while the steel enhances sag control over long spans. Suitable for voltages up to 230kV in distribution lines, the Ortolan ACSR Conductor Cable minimizes line losses and withstands harsh weather, including wind and ice loading. Its cost-effective design makes it popular for utility upgrades and rural electrification, ensuring reliable power delivery with minimal maintenance in overhead transmission and distribution systems worldwide.

Product ASTM B232
Aluminum has become widely used in electrical conductors due to its superior electrical properties. However, for most long-span transmission lines, aluminum conductors require additional mechanical support—galvanized steel wires are commonly used as the core in ACSR conductors.

Construction
ACSR is a concentrically stranded conductor, featuring one or more layers of hard-drawn 1350-H19 aluminum wire stranded around a galvanized steel core. The core may be single-wire or multi-stranded depending on size, with the steel wire available in Class A or B galvanization for corrosion protection. Designed to meet the electrical and mechanical strength requirements of transmission and distribution lines, ACSR offers tailored configurations through optimized combinations of aluminum and galvanized steel wires.
Applications
Widely used as bare cable, it serves both overhead transmission lines and primary/secondary distribution lines.

Raw Material Test
Raw material testing for the Ortolan ACSR Conductor Cable follows ASTM B230 and B498. Aluminum ingots are analyzed for chemical purity (Si<0.1%, Fe<0.2%) and hardness using spectrometers. Steel wires undergo carbon content (0.5-0.8%), galvanization thickness (259g/m² min), and torsion cycles (min 16). Joint compounds are checked for compatibility. The structured process: vendor documentation review, sample extraction, lab testing (hardness Rockwell B80 max), mechanical verification (aluminum tensile 145 MPa), corrosion chamber exposure, and pass/fail determination. This secures high-grade materials for the Ortolan ACSR Conductor Cable's balanced properties and overhead resilience.
Process inspection
Process inspection in Ortolan ACSR Conductor Cable production ensures ASTM B232 adherence. Wire preparation ensures clean surfaces. Stranding machine calibrates for 45/7 configuration with die compression. Tension control prevents loosening. Lubrication application prevents galling. Reeling checks for even winding. Key steps: input material check, machine calibration (tension 500N), in-line diameter measurement, sample pull testing, flaw detection with ultrasonics, and rework for inconsistencies. This ensures the Ortolan ACSR Conductor Cable's tight stranding, even galvanization, and structural integrity for overhead use.
Finished Product
Finished Ortolan ACSR Conductor Cable testing confirms ASTM B232 compliance. Key tests: rated tensile strength (32,300 lbs), conductivity, and weight verification. The process steps: end preparation, machine calibration, incremental tension to rupture, strain gauge recording, post-failure examination, and data logging. Corrosion tests: 500-hour salt spray. Additional: vibration (Aeolian) for endurance. Passing affirms the Ortolan ACSR Conductor Cable's low expansion coefficient, high fatigue life, and suitability for overhead transmission in dynamic conditions.
