"Proper alignment" and "down pressure" are simple phrases to summarize proper anchor installation technique. The Power Installed Screw Anchor (PISA®) wrench transmits torque from the digger’s Kelly bar to the anchor hub. Note: The anchor rod only has to be of sufficient diameter to support the guy load.
Underground enclosures, commonly call handholes, pits, or vaults, come in a variety of shapes and sizes and house critical electrical, telecommunications, gas and water service connections. While each underground enclosure application may be different, there are a few installation fundamentals that should be followed to minimize field damage and help insure many years of use.
In physics, the glow and audible event occurring when an insulator is exposed to excessive voltages is called a corona. It may also be known in the electric industry as “corona discharge,” “plume discharge,” “brush discharge” or “glow discharge.”
Small underground enclosures, commonly called handholes or pits, can come in a variety of shapes and sizes. Enclosures house critical electrical, telecommunications, gas, and water service connections. Each installation and application is different, but there are common installation guidelines that when followed will help to minimize field damage and ensure longevity.
Before specifying underground enclosures, one of the first questions to ask yourself is whether or not the enclosure will be used in deliberate traffic applications or non-deliberate traffic applications.
It is essential to use installing tools and anchors that are properly rated for trucks during the installation of power-installed screw anchors (PISA®). The high torque energy used in installing high-strength anchors requires the control of hazardous torque, which can be safely completed by proper tools.
The CHANCE® grouted rock anchor is designed to be used in situations where the soil is too rocky to use screw anchors, and the rock is fractured preventing the use of wedge style rock anchors. The forged knob on the end of the anchor along with any extension couplings provides the interference fit with the grout. The holding capacity of the anchor is dependent on the bond stress between the rock and the grout. The grouted rock anchor is designed to be used in line with the guy. Failure to install within 5° of alignment with the guy load will significantly lower strength.
When it comes to storm response, Hubbell Power Systems (HPS) knows how to bring the H.E.A.T. (Hubbell Emergency Action Team). H.E.A.T. members have over 30 combined years of storm experience. The team responded swiftly to 2017 Hurricanes Harvey and Irma, and expect to do the same for all upcoming storms. In a time of a natural disaster, customers can be assured they are in the right hands with HPS, due to these key storm response characteristics.

Properly inspecting and storing your rubber insulating gloves could save your life. Rubber insulating gloves are the first line of defense against electric shock. ASTM F496 requires that rubber insulating gloves be inspected and electrically tested at a maximum interval of every six months, whereas field inspection is necessary prior to each use. The date code on the rubber insulating gloves should be checked to verify the most recent testing of gloves is still valid.

The FlexMO has the ability to operate switches from 15 kilovolts to 765 kilovolts with five different open and closed speeds to choose from, and even the ability for two-speed closing and opening, which can help reduce stress on the switch. The FlexMO has the option to use SCADA technology to open and close the switch remotely. Easily switch between local and remote modes on the control panel.
