Overhead Electric Cable
Overhead Electric Cables are essential for efficient power transmission and distribution in urban and rural networks.VERI Cables’ overhead lines are designed to withstand harsh environments and ensure uninterrupted power supply over long distances.
Including ABC (aerial bundled cable), AAC, AAAC, ACSR, etc. So our range of overhead lines generally contains aluminum conductors or aluminum alloy conductors. VERI overhead cable can meet all customer needs. We specialize in providing excellent overhead lines & wires for transmission, distribution, and power network industries.
Types of Overhead Electric Cables
Overhead ABC Cable is mainly used for 600V overhead auxiliary power distribution lines. It is not an electrically insulated conductor and is usually regarded as a bare conductor during installation. The conductor is 1350-H19 aluminum wire, 6201-T81 aluminum alloy or ACSR conductor, concentrically stranded wire and polyethylene, high-density polyethylene (HDPE) or cross-linked Covered with polyethylene (XLPE) to protect against wind and rain.

All Aluminum Conductor(ACC) are widely used in overhead power transmission lines with various voltage levels, because they have such good characteristics as simple structure, convenient installation and maintenance low-cost large transmission capacity, and they are also suitable for laying across rivers and valleys, and the place where special geographical features exist. These conductors are formed by several wires of aluminum, stranded in concentric layers. All the wires have the same nominal diameter. Most common constructions consist of 7, 19, 3 7, and 61 fire.

All aluminum alloy conductors(AAAC) are made of aluminum-alloy 6201, the wire resistance is significantly reduced, and the current carrying capacity is higher than that of ordinary wires. Used as bare overhead conductor for primary and secondary distribution. The AAAC conductor is designed to get better strength to weight ratio and offer improved electrical properties, excellent sag-tension characteristics, and superior corrosion resistance when compared with ACSR. As compared to a conventional ACSR conductor, the lighter weight, comparable strength & current carrying capacity, lower electrical losses, and superior corrosion resistance have given AAAC a wide acceptance in the distribution and medium & high voltage transmission lines.
AAAC Standard: NFC34-125, BS EN 50183, BS 3242 ASTM B399, AS/NZS 1531, NFC 34-125 IEC 61089, certificates of ISO9001, ISO14001.
Aluminum Conductor Steel-reinforced, also called ACSR cable, steel Reinforced Aluminum Conductor, is used as a bare overhead transmission conductor and as primary and secondary distribution conductor and messenger support. ACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity.
Features of ACSR
1. ACSR cables are available in a range of steel contents ranging from 6% to 40% for additional strength.
2. High mechanical strength, Good conductivity, and Large transmission capacity.
3. Corrosion resistance, High-temperature resistance, Unit volume light.
4. Easy to set up, Simple structure, Convenient installation and maintenance.

Aplicații & Project Cases of Overhead Power Cables
Cabluri VERI & DABS Afghanistan
VERI Cables commenced its overhead line project partnership with Afghanistan’s Breshna Sherkat (DABS) Company in 2017, which saw the cables used in projects such as power generation, transmission and distribution across the Afghan country.
Project Name：BoQ_Herat Distribution Networks (Extension and Rehablitation Projects)
“In a recent project, our AAAC cables were used to upgrade the distribution network of a coastal town, ensuring uninterrupted power supply despite severe weather conditions.”
