Complete Overhead Line Hardware — Conductor, Fittings, and Insulators Together
Overhead distribution and transmission line projects require conductors, suspension clamps, strain clamps, insulators, and surge protection to be dimensionally matched and delivered in the correct sequence — procurement teams managing separate suppliers for each component category face avoidable delays when any one item arrives late or out of specification.
LX Cable’s BOMFLEX service consolidates your complete overhead line hardware package:
For EPC contractors and utility procurement teams managing complete line project BOMs, BOMFLEX eliminates the coordination overhead of managing multiple specialized hardware suppliers.
- ACSR, AAAC, and AAC conductors in the required Code Name, cross-section, and drum length
- Suspension clamps, strain clamps, and tension clamps matched to the conductor specification
- Suspension, strain, and pin insulators for the project voltage class and pollution level
- Vibration dampers, connectors, and associated line hardware
- Surge arresters for line and substation overvoltage protection
- Consolidated into a single shipment with coordinated export documentation

Frequently Asked Questions
A standard overhead line installation using ACSR conductors requires: suspension clamps (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.
Yes. Through the BOMFLEX service, LX Cable supplies overhead line fittings alongside ACSR, AAAC, and AAC conductors, suspension and strain insulators, and surge arresters in a single consolidated shipment. 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 (coastal, industrial), 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), system voltage (kV), and environmental conditions (standard, coastal, industrial, 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.
