How Phase Markers are Used Individual Passes During Construction
For industrial uses, Phase markers are reusable PVC markers which snap to power lines during construction and maintenance in order to identify individual passes. They come in a simple snap-fit design as individual markers or in kits of red, white and blue markers. Phase markers have a unique “V” shape design for maximum visibility contrast at all angles. They weigh five ounces, and can withstand 100 miles per hour winds for sustained periods. They can also be customized with a construction company’s logo. Overhead power lines consist of one or more uninsulated electrical cables, suspended by towers or poles. The cables are typically constructed in multiples of three for three-phase power. Phase markers are used to identify individual passes during construction or maintenance. A single-circuit transmission line carries conductors for one circuit, so a three-phase power system supports three conductors. A double-circuit transmission line carries conductors for two circuits.
