Sag in overhead Transmission line conductor refers to the difference in level between the point of support and the lowest point on the conductor.

In this example we will calculate the sag and tension if the conductor supports are at different elevation. Creep is not considered as a factor in final sag in this calculation. Also, loading of the conductors are based on the National Electrical Safety Code

Theseconditions, along with the elastic and permanent elongation properties of the conductor, providethe basis for determinating the amount of resulting sag during installation and long-term operationof the line. Accurately determined initial sag limits are essential in the line design process. Final sags and tensionsdepend on initial installed sags and tensions and on proper handling during installation. The nalsag shape of conductors is used to select support point heights and span lengths so that the minimumclearances will be maintained over the life of the line. If the conductor is damaged or the initial sagsare incorrect, the line clearances may be violated or the conductor may break during heavy ice orwind loadings.

Наконец он заговорил - спокойно, тихо и даже печально: - Нет, Грег, извини. Я не могу тебя отпустить. Хейл даже замер от неожиданности. - Что.

 С учетом обстоятельств, я полагаю, - сказала Сьюзан, - вам все же нужно позвонить директору. Стратмор покачал головой, и капля пота с его лба упала на стол. - Я не хочу никоим образом нарушать покой директора и говорить с ним о кризисе, в то время как он не в состоянии предпринять хоть что-нибудь. Сьюзан понимала, что коммандер прав.

    The maximum dip sag is represented by the value of y at either of support A and B.
