A standard overhead line installation using ACSR conductors requires: ophangklemme (at tangent towers where the conductor hangs), strain or tension clamps (at dead-end and angle towers where the conductor is anchored), conductor connectors (oval sleeves or compression joints for mid-span splices), vibration dampers (Stockbridge type, for spans susceptible to aeolian vibration), and corona rings or grading rings for higher voltage applications. The exact combination depends on the tower configuration, span length, and voltage class.

Fitting compatibility depends on the conductor’s outer diameter and cross-section, not solely the conductor type (ACSR, AAAC, or AAC). Conductors with the same nominal cross-section across the three types will have slightly different overall diameters. Always specify the conductor type and Code Name (or exact outer diameter) when ordering suspension clamps and strain clamps, as undersized or oversized clamp bores can compromise mechanical performance.

A Stockbridge vibration damper is a tuned mass damper clamped to the conductor near the suspension point. It suppresses aeolian vibration — the resonant oscillation induced by wind flowing perpendicular to the conductor — which causes progressive fatigue damage to conductor strands over time. Dampers are typically required for spans over 150–200 meters in open terrain, and for any span in wind-exposed locations. The number and placement of dampers is determined by the conductor type, span length, and local wind regime.

Ja. Deur die BOMFLEX-diens, LX Cable supplies overhead line fittings alongside ACSR, AAAC, en AAC-geleiers, suspension and strain insulators, en stroomafleiders in 'n enkele gekonsolideerde besending. Conductor-to-fitting compatibility is verified as part of the supply process. This is the standard procurement model for complete overhead line projects.

Suspension clamps are typically manufactured from aluminum alloy or ductile cast iron, depending on the conductor weight and installation environment. Strain and tension clamps for ACSR conductors use steel compression ferrules for the steel core with aluminum outer sleeves. For corrosive environments (kus, industriële), hot-dip galvanized or stainless steel hardware is available on request.

Provide the following parameters: conductor type (ACSR / AAAC / AAC), conductor Code Name or cross-section (mm²), application (suspension point, dead-end, mid-span joint, tap-off), stelsel spanning (kV), and environmental conditions (standaard, kus, industriële, or heavily polluted). Upload your line design drawings or material schedule if available, and our team will confirm fitting compatibility and prepare a complete project BOM.
