Every application is different, but they often have something in common with other applications. We normally consider helical guy anchor performance in different types of soil, but different underwater applications can also impact the service life of guy anchors.
When is a roadway like a bridge? Any underground structure or enclosure essentially functions like a small bridge when placed in or near a roadway. The H20 specification (pronounced H-twenty), designed for highway bridges, functions in this application. Enclosures that meet H20 are great for settings that experience vehicular traffic such as loading zones, parking facilities or roadside utilities.
Protect your network and safely secure Multiple Service Terminals (MST) within enclosures. Our new innovative design improves accessibility for simplified diagnosis, saving you time and money.
In many cases, a line worker is faced with several daily tasks which require them to use a single-point-of-contact voltage detector. With a variety of options on the market, knowing which type to use for a project can be challenging. Hubbell Power Systems' CHANCE® Tools brand offers a wide variety of voltage detectors. When using a voltage detector, it is critical to always use a proper length hotstick that complies with company and OSHA-mandated minimum approach distances (MAD). Rubber insulating gloves should never be used as the only form of PPE when using a voltage detector.
Brief History of Materials Used in High Voltage Insulator Construction
As the power grid continued its expansion in the latter part of the 19th century, it became even more critical to safely and effectively insulate the high voltage lines from its surroundings. Telegraph lines had been supported primarily by glass insulators for decades, but these same glass insulators weren’t sufficient for high voltage power lines. Similar in its ceramic nature, but more durable in its construction, porcelain became the primary material for high voltage insulator construction.
MOV, or metal-oxide varistor, surge arresters are widely applied to protect critical utility equipment and improve grid reliability. Surge arresters come in various designs to protect distribution, transmission and substation assets. The characteristics of the surge arrester are customized to meet the varying requirements of each application. IEEE and IEC standards govern the minimum requirements for all surge arresters, however other characteristics must be considered to meet Hubbell’s demanding quality standards.
There are numerous traits that ensure the quality and longevity of MOV surge arresters. Five key characteristics tend to overshadow others. These include:
During line work, it is commonplace for lines to be de-energized and grounded for worker protection in the event there is a fault current, which could be due to a variety of issues. In this blog, we will look at some common misconceptions about temporary personal protective grounding.
If you have ever driven along a river, the ocean, or a large lake and come across a massive, imposing, messy stick nest on a distribution or transmission power line, chances are you are looking at a nest of an osprey. These large raptors (birds of prey) with a global distribution are well-adapted to specialize on small to large sized fish. They nest along fish-bearing waterbodies - historically in the tops of broken tree snags, but as power poles became common across the landscape, they became valuable real estate for nesting osprey, particularly those near water.

At Hubbell Power Systems, Inc. (HPS), we are committed to providing our customers with outstanding service, whether in our hometowns or halfway across the world. In 2019, prior to COVID-19, two engineers from HPS spent two weeks giving presentations and training crews in Sri Lanka on the application and installation of CHANCE® helical piles and anchors manufactured by HPS. Here is their story:
