Overhead Transmission Line All Aluminium alloy Conductor AAAC cable Aerial Bare Conductor

Product Description

All Aluminum Alloy Conductor (aaac) Applications
7 and 19 strand construction is suitable for bare overhead reticulation of medium spans, normally at low and medium voltages.
37 and 61 strand construction is suitable for transmission and subtransmission lines where homogeneous construction can reduce line losses and improve corrosion resistance in conductors with similar strength to ACSR types.

All Aluminum Alloy Conductor (aaac) Features
Moderate-strength all aluminum alloy conductor has good sag characteristics, can increase the transmission tower span. It also has excellent resistance to overload and fatigue properties. Compared with the same diameter ACSR conductor, the vertical load of AAAC reduced by 10% with the equal horizontal load. Wire surface damage resistance. It has great corrosion resistance than ACSR, avoid electrochemical corrosion between aluminum and galvanized steel wire, thus have long running life.

All Aluminum Alloy Conductor (aaac) Construction
Moderate-strength all aluminum alloy conductor concentric-lay stranded by aluminum wires of 230 ~ 265MPa tensile strength, similar in construction and appearance to 1350 grade aluminum conductors.

1. AAAC / All Aluminum Alloy Conductor Application
Used as bare overhead conductor for primary and secondary distribution. Designed utilizing a high-strength aluminum-alloy to achieve a high strength-to-weight ratio; affords good sag characteristics.

(1)AAAC conductors are extensively used for overhead distribution and transmission lines adjacent to ocean coastlines where there can be a problem of corrosion in the steel of an ACSR construction.

(2)The aluminum alloy conductors are used in replace of single-layer ACSR conductors to reduce power loss in overhead distribution and transmission lines,when replacing the aluminum conductor steel reinforced , the AAAC can save 5-8% of the construction cost.

(3)AAAC referred to have higher strength but lower conductivity than pure aluminum Being lighter, alloy conductors can sometimes be used to advantage in replace of the more conventional ACSR.

2. AAAC / All Aluminum Alloy Conductor Features
Aluminum alloy conductors have a number of advantages over the use of the ACSR or AAC(all aluminum conductors).
Lower power losses than for equivalent single aluminum-layer ACSR conductors. (The inductive effect of the steel core in the ACSR is eliminated).
• Simpler fittings than those required for ACSR.
• Excellent corrosion resistance in environments conducive to galvanic corrosion in ACSR.
• Strength and sag approximately the same as for equivalent 6/1 and 26/7 ACSR conductors.
• Outside diameters are the same as for standard ACSR conductors, permitting interchangeability of fittings.
• Greater resistance to abrasion than that for 1350 wires in all-aluminum or ACSR conductors.
• High tensile strength as compared to AAC conductor.
• Higher conductivity as compared to ACSR conductor.
