Conductors For Transmission Lines:

14.1TYPES OF CONDUCTORS:

14.1.1In the early days conductor used on transmission lines were usually Copper, but Aluminium Conductors have Completely replaced Copper because of the much lower cost and lighter weight of Aluminium conductor compared with a Copper conductor of the same resistance. The fact that Aluminium conductor has a larger diameter than a Copper conductor of the same resistance is also an advantage. With a larger diameter the lines of electric flux originating on the conductor will be farther apart at the conductor surface for the same voltage. This means a lower voltage gradient at the conductor surface and less tendency to ionise the air around the conductor. Ionisation produces the undesirable effect calledcorona.

14.1.2The symbols identifying different types of Aluminium conductors are as follows:-AAC : All Aluminium conductors.AAAC : All Aluminium Alloy conductorsACSR : Aluminium conductors, Steel-ReinforcedACAR : Aluminium conductor, Alloy-ReinforcedAluminium alloy conductors have higher tensile strength than the conductor of EC grade Aluminium or AAC, ACSR consists of a central core of steel strands surrounded by layers of Aluminium strands. ACAR has a central core of higher strength Aluminium Alloy surrounded by layer of Electrical-Conductor-Grade Aluminium.

14.1.3The alternate layers of a stranded conductor are spiraled in opposite direction to prevent unwinding and make the outer radius of one layer coincide with the inner radius of the next. Standing provides flexibility for a large cross-sectional area. The number of strands depend on the number of layers and on whether all the strands are of the same diameter. The total number of strands in concentrically stranded conductors, where the total annular space is filled with strands of uniform diameter is 7,19,37,91 or more.

14.2STANDARD SIZES OF CONDUCTOR FOR LINES OF VARIOUS VOLTAGES:

14.2.1The following sizes have now been standardised by CEA for transmission lines of different voltages--(i) For 132 KV lines:'Panther' ACSR having 7-strands of steel of dia 3.00 mm and 30-Strands of Aluminium of dia 3.00 mm

(ii) for 220 KV lines:'Zebra' ACSR having 7-strand of steel of dia 3.18 mm and 54-Strands of Aluminium of dia 3.18 mm.

(iii) for 400 KV lines:Twin 'Moose' ACSR having 7-Strands of steel of dia 3.53 mm and 54-Strands of Aluminium of dia 3.53 mm.

14.3SPECIAL REQUIREMENTS OF CONDUCTORS AS PER UPSEB SPECIFICATIONS;

14.3.1No joints are permitted in Steel core as well as in the outer most Aluminium layer of the conductor.

14.3.2The composite conductors are subjected to following type tests:-(a) DC Resistance

(b) Ultimate Tensile Strength

(c) Surface condition Test**Only for 'Moose' conductor for use on 400 KV lines

(d) Corona Test*

(e) Radio-Interference Voltage Test.*

14.4ALL ALUMINIUM ALLOY CONDUCTORS (AAAC)

14.4.1Recently AAAC are being used in some SEBs to overcome menace of pilferage of ACSR and AAC conductors, particularly lower voltage lines. AAAC can not be re-cycled and it does not have any common use for other purposes, as that in case of pure Aluminium.AAAC is made out of heat treated Aluminium-Magnesium-Silicon Alloy designed as 64401 T 81 covered under IS:9997:1991 containing 0.6-0.9% Magnesium and 0.5-0.9% Silicon.

14.4.2Besides use of AAAC on lower voltage lines from the point of view of avoiding its pilferage, it is also better for use in coastal areas to avoid corrosion problem prevalent in Steel core of ACSR conductors.

14.5BUNDLED CONDUCTORS

14.5.1The combination of more than one conductor per phase in parallel suitably spaced from each other used in overhead Transmission Line is defined as conductor bundle. The individual conductor in a bundle is defined as Sub-conductor.

14.5.2At Extra High Voltage (EHV), i.e. voltage above 220 KV corona with its resultant power loss and particularly its interference with communication is excessive if the circuit has only one conductor per phase. The High-Voltage Gradient at the conductor in the EHV range is reduced considerably by having two or more conductors per phase in close proximity compared with the spacing between conductor-bundle spaced 450 mm is used in India.

14.5.3The three conductor bundle usually has the conductors at the vertices of an equilateral triangle and four conductors bundle usually has its conductors at the corners of a square.

14.5.4The current will not divide exactly between the conductor of the bundle unless there is a transposition of the conductors within the bundle, but the difference is of no practical importance.

14.5.5Reduced reactance is the other equally important advantage of bundling. Increasing the number of conductor in a bundle reduces the effects ofcoronaand reduces the reactance. The reduction of reactance results from the increased Geometric Mean Radius (GMR) of the bundle.

14.6.0CONDUCTORS FOR RIVER CROSSING USED IN UPSEBFor river crossing of 132 KV, 220KV and 400 KV transmission lines, the following conductors are being used in UPSEB:-i. For 132 KV Lines:Special 'Panther' conductor, i.e. one Aluminium layer of ACSR 'Panther' conductor removed having 7-strands of Steel of 3.00 mm dia plus 12-Aluminium strands of 3.00 mm dia.ii. For 220 KV Lines:Special 'DEER' conductor, having 17-Strands of Steel of dia 2.69 mm and 12-strands of Aluminium of 4.65 mm dia.iii. For 400 KV Lines: 'Moose' ACSR

Current Carrying Capacity of Overhead Transmission Line ACSR Conductor.

21.1 INTRODUCTION

21.1.1The thermal capabilities of transmission transmission lines in Power System are evaluated based on the criteria of maximum operating or design temperatures of the transmission line conductors and the transmission losses.21.1.2The thermal rating of conductor is dependent on the following factors :A. Meteorological/Environmental Conditions1. Solar radiation.2. Wind velocity.3. Ambient temperature.B. Conductor surface Characteristics1. Age of the Conductor.2. Maximum design conductor temperature.3. Allowable losses of strength of aluminium metal at design temperature.21.1.3The maximum value of temperature at which transmission metal at design temperature. Operate in India is 650C for conductors as per provisions of IS:802 (Part-I) 1973. However, to increases loading capabilities of transmission lines, the matter is under active consideration by Bureau of Indian Standards, Central Electy. authority, State Electy Boards and other utilities etc. for increasing the maximum conductor design temperature from 650C to 750C as it has been observed that there is no loss of strength of aluminium metal at 650C. But it has to be ensured that the transmission line towers are designed suitably, fo that there is no violation of ground clearance under any circumstances due to safety considerations. This would significantly help in improving thermal loading capability of transmission lines, without infringement in ground clearances.

21.2 HEAT BALANCE EQUATION OF ELECTRICAL CONDUCTORSThe current carrying capacity rating is computed by using the following formula under steady state condition of wind velocity, temperature, solar radiation and electric current.Qc+ Qr= I2R + QsWhere-I2R = Heat generated in the conductor due to flow of current ' I ' in Amperes, R is the resistance of the conductor per meter.Q8= Solar Heat Gain in Watts per meter of Conductor.Qc= Convection heat loss in Watts per meter of ConductorQr= Radiated Heat Loss in Watts per meter of Conductor.From the above equation, current carrying capacity I can be determined as-I =Qc+ Qr- Qs/ RAmpereThe effect of Heat Gain due to Magnetic Heat and Corona Heating and Heat Loss due to Evaporation is usually negligible, hence not considered.21.3 CURRENT RATING OF VARIOUS CONDUCTORS21.3.1The size of the conductor used for transmission lines of various voltage class has now been standardized, which are as fallows-400kv - 'Moose' ACSR220kv - 'Zebra' ACSR132kv - 'Panther' ACSR21.3.2However, recently in some cases 'moose' conductor has been used on 220kv lines for evacuation of bulk power from generating station, such as Unchahar Power Project, In case of 66kv lines which have been up-graded to 132kv, the conductor used is 'Dog' ACSR. Accordingly, the current capacities of the above conductors are temperature of 47.50C. for new as well as old conductors for the designed maximum conductor temperature of 650C as well as 750C.

NOTE :1. It is observed that the temperature at some place of UP State goes as high 47.50C during the months of April, May & June. There fore current carrying capacities of conductors indicated above, are for worst condition of ambient temperature. However, the current carrying capacity of the conductor of the increases as the ambient temperature decreases.2. The current carrying capacity of the conductor also increases with the age of the conductor as would be observed from the above tabel.21.4 POWER TRANSMITTED21.4.1The power transmitted for any size of conductor depends on its current carrying capacity and can be calculated from the following formula-Power in KW =3 V I Cos Power in KW =3 V I Cos / 1000Where-Cos = Power Factor (P.F.)V = Voltage in KVI = Current in Amp.

Assuming Power Factor of 0.8 lagging, power transmitted at various voltages can be calculated approximately as follows-a. At 132 kvPower in MW =3 132 x I x 0.8 / 1000= 0.1828992 xI=0.183 xIb. At 220 kvPower in MW =3 220 x I x 0.8 / 1000= 0.305 xIc. At 400 kvPower in MW =3 400 x I x 0.8 / 1000= 0.554 xI

Thus value of power transmitted can easily be calculated at 132 kv or 200 kv or 400 kv for a given value of current.21.4.2Normally for continuous operation the transmission lines used on various voltage are designed to carry or transmit maximum power loads at the designed maximum conductor temperature of 650C as followsAt 132 kv with 'Panther' ACSR = 75 MVAAt 220 kv with 'Zebra' ACSR = 200 MVAAt 400 kv with 'Moose' ACST = 500 MVA21.4.3It is worth considering that the maximum permissible conductor temperature for continuous operation on transmission lines may be introduced as 750C in order to raise the current rating of the conductor. This issue is under active consideration and IS:802-1973 is under revision.21.4.4It is observed that the current carrying capacity of any conductor at any particular temperature is lowest during 10 to 14 hours of a day. Assuming maximum permissible conductor temperature of 750C, the value of current carrying capacities of 'Dog', 'Panther', 'Zebra' and 'Moose' ACSR conductor during 10 to 14 hours of a day at different ambient temperatures for various months of a year for the conductor of ages (a) up to one year (b) between 1 to 10 years and (c) Above 10 years given in the Table I, II, III & IV respectively hereinafter.
