White Papers

Surge protection devices (SPDs) are an indispensable component of wayside detection systems (WDS) and other railway electronic and electrical equipment and systems. It is critical for a railway operator to select appropriate SPDs that meet the technical requirements of the equipment used in railway systems.

This paper describes several main functions of TC-ER – namely, powering DC Defenders, AP antennas, and factory automation – and the benefits of buying this type of cable in bulk spools. It concludes with information about Transtector’s new line of TC-ER bulk cable.

The popularity of solar power is on the rise in the U.S. and worldwide. With it is a growing need to protect photovoltaic (PV) power systems from transient voltage caused by lightning strikes and other factors. This paper touches on growing solar use projections before discussing the special surge protection needs of PV systems.

In this white paper, we discuss some of the qualities of 10 GbE PoE++ data networks, the surge protection challenges they present, and how one surge protection technology, SASD, is meeting those challenges. We conclude with information about a new Transtector SPD that is designed to protect 10 GbE PoE++ networks.

Tarana Wireless recently faced a big challenge. The California-based radio manufacturer needed to recommend effective surge protection to users of its radios. The radios, powered by DC cables running the length of the towers, were vulnerable to damage through lightning strikes and other surge events. The surge protection needed to be robust and reliable, as the radios are in areas with high exposure to lightning storms.

The deployment of radios, that send and receive data over fiber and are powered by a pair of DC power cables, has been growing year over year. Transtector brought tower top DC surge protection to the market long before the installation method became as prevalent as it is today. As early pioneers of surge protection devices (SPDs) for DC/fiber radios, Transtector has witnessed the growth of this type of deployment go beyond network carriers to include WISPs, military, and industrial applications, as well as, other industries and markets.

Transtector has over 50 years of expertise providing surge protection devices (SPDs) to protect critical data signals, AC/DC, and RF applications. Transtector solutions are used to protect mission critical applications such as 9-1-1 call centers, data centers, cell tower sites, missile defense applications, and many more.

AXIS Communications is the global leader in the network camera and video encoder markets. AXIS customers deploy PoE-fed cameras in harsh outdoor environments. Designers, installers and end users must ensure signal integrity in these mission-critical applications. Robust, reliable surge protection devices (SPDs) help to do just this.

The latest NEC 2020 Sections detail the requirement of surge protection devices (SPDs) in specific applications. In this document, we will go through each section and identify the application, provide examples, and identify potential surge protection solutions.

PoE network engineers should deploy high-quality external surge protection devices (SPDs) to help ensure safe, secure network operation, reduce downtime, minimize site visits, and ultimately, decrease overall equipment costs. Integrating surge protection into radios, power injectors, mid-spans, and other critical power-over-Ethernet (PoE) devices, however, is an example of combining two devices that should remain separate. Unfortunately, many providers of this equipment promote their built-in surge protection as an added benefit rather than the potential weak link it truly is.
