Insulated covered line wire for safe overhead power delivery.
ACSR core covered wire for strong, stable overhead distribution.
Insulated line wire with UV-resistant jacket and ABNT/IEC certification.
Reliable overhead conductor – hard aluminum, ICEA-compliant insulation for outdoor use.

Application

 

Overhead Insulated Covered Line Wire is a single-core conductor designed for low-voltage aerial distribution systems, offering enhanced electrical safety and environmental durability compared to bare overhead wires. It consists of a hard-drawn aluminum conductor (or aluminum alloy) covered with a UV- and weather-resistant thermoplastic or cross-linked polyethylene (XLPE) layer.

Unlike fully insulated bundled cables, covered line wire maintains a single-phase open construction, allowing for simpler installation and traditional spacing, while still providing basic protection against accidental contact, tree branches, wind-blown debris, and wildlife. It helps reduce outages and improves public safety in densely populated or vegetated areas.

This cable is commonly used in overhead service drops, secondary distribution networks, and retrofit projects where bare conductors pose safety or maintenance concerns. It supports operating voltages up to 0.6/1kV and is suitable for both urban and rural networks.

• Conductor: Stranded, circular compressed aluminum, aluminum-alloy, copper.
• Outer Insulation: Thermoplastic polyethylene (PE) or cross-linked polyethylene (XLPE) in Black with Weather or UV resistant.

CHARACTERISTICS

 

Category Technical Description Typical Applications
   Applicable Standards  ICEA S-70-547 (Covered conductors)- ICEA S-61-402 (Weather-resistant wire)- BS 6485 (UK) For overhead low-voltage and medium-voltage networks where partial insulation is needed
   Cable Type Covered Line Wire – overhead conductor with a thin insulating covering, not full dielectric insulation Used where touch protection is needed but air clearances remain standard
   Conductor Material Hard-drawn aluminum (1350) or ACSR– Stranded Class AA/ A, or concentric lay conductors Chosen for mechanical strength and lightweight spans
   Covering Material High Molecular Weight Polyethylene (HMWPE) or Thermoset PE– May include carbon black for UV Provides weather, abrasion, and UV protection without being rated as full insulation
   Insulation Level Covered, not insulated: Does not meet full dielectric withstand per IEC or UL definitions Requires standard air clearance; installed on insulators, not directly touch-safe
   Voltage Rating LV: 600 V – 1000 V– MV: typically up to 15 kV (in triplex or single conductors) Used in North America, UK, or tropical markets for cost-effective safety upgrade
   Installation Type Installed like bare conductor on standard poles with insulators- Can be triplexed or single Suitable for tree-rich or semi-urban areas to reduce vegetation faults
   UV/Weather Resistance Yes – excellent in UV, rain, chemical exposure Ideal for hot, humid, or polluted industrial zones
