Overhead Line Cables & Wires Manufacturer from China
Overhead Line Wires Types
The main classifications of bare conductor are AAC (All Aluminium Conductor), AAAC (All Aluminium Alloy Conductor) or ACSR (Aluminium Conductor Steel Reinforced). AAC is most commonly found in urban areas with frequent supports and short spans. It is also used in coastal regions where salt in the air can cause corrosion - the All Aluminium wire providing corrosion resistance - and specified for use in the railway industry for OHL electrification. AAAC tend to be specified where greater mechanical resistance is required and where there is a reduced sag characteristic. The ACSR, with its steel reinforcement provides additional strength and where the spans run for larger distances, such as across rivers.
Bare Aluminum Conductors Standards
The overhead line wires are manufactured in accordance with various national standards and can be sized appropriately
- including ASTM B231, TS IEC 1089, DIN 48201, BS 215, and Spanish standard UNE 21.018.
Overhead ABC Cables
Also within the family of Overhead Lines are
Aerial Bundle Cables. These low voltage and medium voltage cables, abbreviated as ABC, are wrapped in insulation, with the medium voltage variants also having an outer sheath. They lay up and twist multiple insulated single cores together - medium voltage ABC also tend to have a steel wire support running through the centre for applications including street lighting and secondary pole to pole service cables. They're also often used in temporary power installations in the construction industry. The insulation provides a protective barrier in the event of sparks or shorts.
