Product Overview
TYIR / TYIR 50 OL-AL Cable is a 0.6/1kV aerial bundled cable (ABC) with aluminium phase conductors and a steel-aluminium neutral carrier, PVC insulated and twisted into a bundle. Manufactured to Romanian standard ST 125-2006 and harmonised European standard SR HD 626 S1. Phase conductors use concentrically stranded aluminium (RM); the neutral conductor is a steel-aluminium composite carrier (ACSR type) providing both current return path and mechanical support for overhead spans. TYIR covers standard configurations; TYIR 50 OL-AL extends to 64 additional configurations for combined phase/street lighting networks.
Phase Conductor
Concentrically stranded aluminium (RM). Hard drawn for aerial mechanical strength. Available from 10mm² to 95mm² cross-section.
Neutral Carrier
Steel-aluminium composite (ACSR type). Steel core for tensile strength + aluminium layer for conductivity. Self-supporting messenger.
PVC Insulation
Weather-resistant black PVC. 70°C continuous, 160°C short-circuit. UV stabilised for decades of direct overhead exposure.
Twisted Bundle
Phase and neutral conductors twisted together. Eliminates wind clashing, reduces visual impact, single-drum installation.
ABC Advantage
No phase-to-phase short circuits from wind or wildlife. Lower electrocution risk. Reduced maintenance vs bare open-wire lines.
Street Lighting Ready
Dedicated auxiliary conductors (16–50mm²) for public lighting circuits in the same bundle — one cable, all services.

Typical Applications
TYIR aerial bundled cables replace bare open-wire overhead lines in LV distribution networks. The twisted insulated bundle eliminates phase-to-phase faults while the steel-aluminium neutral carrier provides self-supporting messenger capability:
Residential Distribution
Three-phase supply for household subscribers. Bundled construction prevents faults from wind, trees, and wildlife.
Rural Electrification
Cost-effective overhead for rural areas. Self-supporting neutral carrier eliminates separate catenary wire.
Street Lighting Networks
Combined phase + lighting in one bundle. 16–50mm² auxiliary cores for public lighting circuits alongside main phases.
Utility Network Upgrades
Retrofit existing bare lines with insulated bundle. Same pole infrastructure, dramatically improved safety.
Eastern European Markets
ST 125-2006 certified for Romania and neighboring countries. SR HD 626 S1 ensures EU-wide acceptance.
Industrial Site Supply
Temporary and permanent overhead power to factories, workshops, and processing plants.
