Niskie napięcie (zapisywane skrótowo jako nN) – w elektrotechnice oraz elektronice oznacza napięcie elektryczne w obwodach prądu przemiennego do 1000 woltów przy częstotliwości nie większej niż 60 Hz, oraz napięcie w obwodach prądu stałego do 1500 woltów.

Option:

conflict of low-voltage (LV) power line cables

Example:
California officials have estimated that
between one and three percent of wildland fires in California begin
with tree and power line conflicts.

Whether a community experiences conflicts between trees and
utility lines in the first place frequently hinges on community
planning. Newer suburbs and central city areas commonly place
distribution lines underground, eliminating the conflict altogether.
Relocating long-established overhead infrastructure in older
communities, however, can be impractical and cost millions of
dollars per mile.118 Poor planning in some cities has literally laid
the roots for future conflict

Utility conflicts occur as a result of a proposed highway design when a utility facility is in conflict with the proposed highway facility, other utility installations, or noncompliance with the Utility Accommodation Rules (UAR) (2). It is then necessary to address or clear such conflicts by using strategies such as (a) introducing a design change to the horizontal or vertical alignment of the proposed highway facility, (b) removing, relocating, or otherwise adjusting the utilities in conflict, and (c) by a mechanism other than a highway facility design change or utility adjustment such as an engineering solution. During the process of detecting, confirming, and resolving conflicts, a suspected conflict may also be removed if a subsequent
evaluation determines that the utility facility is not in conflict.


For example, one utility company felt that TxDOT does not inform its contractors that utilities are not in physical conflict. Sometimes lines are not in physical conflict but perhaps a construction conflict and contractors call utility companies asking them to move or relocate the line


A critical process for the timely development and delivery of highway construction projects is the early identification and depiction of utility interests that may interfere with proposed highway facilities
