Traffic signal support poles with a span wire assembly are referred to as what?

Traffic signal support poles that utilize a span wire assembly are commonly referred to as strain poles. These poles are specifically designed to handle the tension created by the span wire, which supports the signals and other equipment. The strain from the wire requires the poles to be robust and secure, enabling them to maintain stability under various weather conditions and loads.

Strain poles are strategically placed to help balance the loads and resist the forces acting on the span wire. Unlike standard poles, which are typically anchored directly in the ground and primarily support the signal directly above them, strain poles are often used in configurations where multiple signals need to be supported from a single point without direct ground anchoring.

Understanding this distinction is essential for traffic signal technicians, as the proper selection and installation of strain poles can significantly impact the reliability and safety of traffic signal operations.
