Precision-manufactured high-purity copper components designed for switchgear assemblies, substations, and grounding installations across Karachi, Lahore, and Islamabad.
Accelerating power infrastructure, China-Pakistan Economic Corridor (CPEC) initiatives, and renewable energy adoption drive exponential demand for high-spec bare copper conductors.
The industrial transformation in Pakistan is advancing at an unprecedented pace. With heavy capital deployment across mega energy projects under the China-Pakistan Economic Corridor (CPEC) framework, modernizing transmission and distribution networks has become paramount. Bare copper stranded wire functions as the vital backbone of this nationwide infrastructure overhaul. From the National Transmission & Despatch Company (NTDC) transmission corridors to regional power distribution utilities (DISCOs like K-Electric in Karachi, LESCO in Lahore, and FESCO in Faisalabad), electrical engineers require pure, uncompromised conductive copper to withstand extreme operating temperatures, seasonal monsoon surges, and high soil corrosion levels.
In Pakistan's power sector, bare copper stranded wire is predominantly deployed for substation grounding grids, lightning protection masts, overhead transmission lines, and neutral grounding conductors. Electrical safety and network resilience rely heavily on electrolytic-tough-pitch (ETP) bare copper possessing ≥99.99% purity. As Pakistan ramps up investments in high-voltage 220kV and 500kV substations, substandard or scrap-recycled copper cables lead to catastrophic earth fault failures, equipment burnout, and hazardous step-and-touch voltage spikes. Our factory customizes bare copper conductors adhering strictly to international norms such as ASTM B8, BS EN 13602, and IEC 60228 Class 2 standards to assure maximum safety for Pakistan's major EPC contractors.
Manufactured using premier electrolytic copper cathode raw materials, ensuring 100% IACS conductivity without brittle inter-crystalline impurities.
Designed for harsh coastal environments in Gwadar & Karachi, and robust industrial earthing across Special Economic Zones (SEZs) like Rashakai and Dhabeji.
Engineered flexibility and high tensile strength tailored for solar array bonding in the Cholistan desert and telecommunication tower lightning arresters.
