    6 Factors Affects to Determine Transmission Tower Height

    Transmission Lines

    mplgmg March 1, 2017

     transmission tower height The transmission tower height is also important factors to consider while design of transmission lines. There are several factors taken in to consideration while deciding and creating tower height of electrical power lines. Following are those factors which taken in to considerations.

    • Minimum ground clearance
    • Maximum Sag of Conductor
    • Length of Suspension Insulators
    • Vertical space between conductors
    • Ground Wire Location
    • Angle of Shield

    Following are some comprehensive details of the mentioned factors which affect to determine the transmission tower height in power engineering.

    1. Minimum ground clearance

    Minimum ground clearance is showed in accordance with all technical requirements and specifications. Normally minimum ground clearance in Electrical power transmission line varies from country to country depending on the rules and regulations which they Patrice.

    1. Maximum Sag of Conductor

    In Maximum sag of conductor depend on several factors of the conductor. Following are the factors which taken in to account while determine maximum sag of conductor in electrical power lines

    • The Size of Conductor
    • Type of Conductor (ACC, ACSR, AAAC, ACAR)
    • Climatic Conditions
    • Length of Span

    In most cases maximum sag of conductor are occurs rapidly under the maximum temperature of conductor and sill wind condition too.

    The maximum sag of electrical power line also consider in the fixing the height of the Transmission line support too. In cold countries the maximum sag can occur at the minimum temperature and ice coated at power conductor.

    3.Length of Suspension Insulators

    Length of Suspension Insulators is one of the main factors to determine the height of the transmission line tower.

    Following are some of the factors affect on the length of suspension insulators.

    Lowest cross arm in case of delta type, vertical type suspension Power transmission tower.

    1. Vertical space between conductors

    Vertical space between power conductor are also play main role in spacing between the cross arms.

    5.Ground Wire Location

    Main factors which affect to determine the location of earth wire on transmission tower are the minimum difference in

    • Suspension insulator length
    • Drop of earth wire to Suspension claps
    • Angle of shield.

    6.Angle of Shield

    The main function of ground wire of power transmission lines are to provide necessary protection on transmission lines against the direct and indirect lightening stocks.

    Function of ground wire is mainly based on the selection of angle of shields and coordinates of ground wire sages with that conductor.

    Location of the ground wire consider the highest of the ground wire peak

    Ground wire is also located.

    The effect of the creep in side steel ground wire can be negligible while consideration of the sag of the conductor.

    The mentioned 6 factors are affect to determine transmission tower height in power transmission engineering filed.
