AAC Conductors are made out of Hard drawn EC Grade (min 61% IACS) Aluminium wires stranded in successive layers in opposite direction to form the Aluminium stranded AAC Conductor up to 61 wires.
All Aluminium Conductors are manufactured from electrolytically refined aluminium. They have a high level of purity; the minimum accepted level of aluminium is 99.7%. This product is also known as aluminium stranded conductor, as it is constructed of one or more strands of aluminium wire depending on the intended usage. As a consequence of this high level of purity, AAC Conductors are mainly used in areas where spacing is short and supports are close.
ACSR conductor consists of a solid or stranded steel core surrounded by strands of aluminium. ACSR conductor is available in a range of steel strengths varying from 6% up to 40%. The higher strength ACSR conductors are used for river crossings, overhead earth wires, and installations involving extra long spans. Against any given resistance of conductor, ACSR conductor may be manufactured to have different tensile strengths as per requirement. The principal advantage of these conductors are their high tensile strength and light weight, covering longer spans with less supports. Due to the greater diameter of an ACSR conductor much higher corona limit can be obtained, giving a big advantage on high and extra high voltage overhead lines.
Key Benefits :
The principal advantage of these conductors are high tensile strength so that they are used for longer spans with less supports. Due to the greater diameter of ACSR cond uctors a much higher corona limit can be obtained causing big advantages on high as well as extra high voltage overhead lines.
ACSR conductors consist of a solid or stranded steel core surrounded by strands of aluminum (E.C. GRADE). ACSR conductors are available in a wide range of steel, containing carbon from 0.5% to 0.85 %. The higher strength ACSR conductors are used for river crossings, overhead ground wires, installations involving extra long spans etc. Against any given resistance of conductor, ACSR may be manufactured within a wide range of tensile strength as per the requirement.
Key Benefits :
The principal advantage of these conductors are high tensile strength so that they are used for longer spans with less supports. Due to the greater diameter of ACSR conductors a much higher corona limit can be obtained causing big advantages on high as well as extra high voltage overhead lines.
Application
Used as bare overhead transmission cable and as primary and secondary distribution cable. ACSR Offers optimal strength for line design. Variable steel core stranding enables desired strength to be Achieved without sacrificing ampacity.
Construction
ACAR has aluminium 1350 H-19 wires concentrically stranded around a 6201-T81 aluminium
Alloy core. Typically, the 6201-T81 is the conductor core, but in certain designs, the 1350 H-19 And the 6201-T81 wires may be stranded in the same layer.
AACSR Bare Conductor is a concentrically stranded conductor composed of one or more layers of 6201 -T81 aluminum alloy wire stranded over a high-strength zinc coated steel core. The core may be single wire or stranded depending on the requirement customer.
The proportions of aluminum alloy and steel can be varied to obtain the relation between currentcarrying capacity and mechanical strength best suited to each application.
Core wire for AACSR is available with Class A, B or C galvanizing; "aluminized" aluminium coated (AZ): or aluminium clad (AW).
Key Benefits :
Used as bare overhead transmission cable and as primary and secondary distribution cable. AACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity.
OPGW is primarily used by the electric utility industry, placed in the secure topmost position of the transmission line where it it â??shieldsâ?� the all-important conductors from lightning while providing a telecommunications path for internal as well as third party communications. Optical Ground Wire is a dual functioning cable, meaning it serves two purposes. It is designed to replace traditional static / shield / earth wires on overhead transmission lines with the added benefit of containing optical fibers which can be used for telecommunications purposes. OPGW must be capable of withstanding the mechanical stresses applied to overhead cables by environmental factors such as wind and ice. OPGW must also be capable of handling electrical faults on the transmission line by providing a path to ground without damaging the sensitive optical fibers inside the cable.
Medium voltage power cable. Voltage 1.8/3.6 up to 26/35KV
XLPE power cable has high electric strength, mechanical strength, high-ageing resisting, environmetal stress resisting antichemical corrossion, and it is simple construction, using convenient and higher operating of long term temperature. It can be laid with no drop restriction.
Various of flame-retardant and non-flame retardant XLPE cable can be manufactured with three technology(peroxide, silane and irradiation crosslinking). The flame-retardant cable covers all kinds of low-smoke low-halogen low-smoke halogen free, and non-smoke nonhalogented and three classes of A, B, C.
Our XLPE power cable can be manufactured according to IEC 60502, IEC 60332, and IEC 60754. Some of indexes are superior to above international standard IEC.
Some of special XLPE power cable can be manufactured according to the other standards required by customs.
XLPE power cable having higher long-term working temperature and greater current rating, at the same environment XLPE cable may be reduced size(nominal cross-section)1or 2 class in comparison with paper and PVC cable. This is not only improve the quality and properties of prod ucts, but also reduce cables production costs.
Low Voltage cable with PVC insulated and sheath is used as power distribution and transimssion line at rated voltage 0.6/KV which can be fixed installed.
Operating Characteristc
1)The long-term working tempeture of cable should be not higher than 70 degree.
2)When core is in short-circuit (Max. 5s), the tempeture should not exceed 100 degree.
3)While installation the ambient tempeture should not be lower than o degree, and bending radius should not be less than 10 times of outer diameter.
PVC insulated PVC sheathed power cable (VV) with steel wire or steel armor Cable.
For laying in doors, inducts and in tunnels, but unable to bear pulling force and pressure.
