Aluminum Cable Installation Best Practices

Industry consensus is that improper connection operation accounts for over 70% of all aluminum cable early failure cases, rather than the product itself. That’s why we have collected the Step-by-Step Aluminum cable installation practices for our customers

Following correct installation procedures can eliminate 98% of common aluminum cable operation faults such as joint overheating, which is the top issue reported in every-yesr’s power industry maintenance records.

Pre-inspect full length of aluminum cable to confirm no insulation scratch or conductor deformation before laying on site

Use aluminum-specific crimp lugs and anti-oxidation paste for all connection points to avoid galvanic corrosion caused by direct copper-aluminum contact

Reserve 3-5% extra cable length at every laying section to offset physical elongation under high temperature weather

Run 500V megger test after full installation, confirm insulation resistance stays above 0.5MΩ before connecting to power grid

Besides proper installation methods, regular maintenance can extend the service life of aluminum cable by 8-10 years on average, without extra high cost for power operators.

You are suggested to run infrared temperature check for all cable joint points once every 6 months, especially for lines operating under 80%+ full load. Replace aged insulation accessories immediately if you find any crack or temperature rise exceeding 50℃ above ambient level. Avoid placing heavy loads directly on top of laid aluminum cable, to prevent physical damage to inner conductor.
