There are different methods to produce rubber insulating gloves. Hubbell Power Systems’ CHANCE® Lineman Grade™ gloves are produced using an environmentally responsible aqueous dipping process. 

Rubber insulating gloves are a critical piece of Personal Protective Equipment (PPE) when working on energized power lines. They should be visually inspected every day before use and properly stored when not in use. Here are 6 tips for inspection of rubber insulating gloves. 

Porcelain is a key component used in the construction of electrical components throughout the electrical grid, including high voltage bushings. It is non-hydroscopic and will not enable mold to develop in high humidity environments. In addition, porcelain a non-organic material so it will not deteriorate over the life of the product.

The CHANCE® DC hi-pot adapter has proven to be a very valuable tool for locating faulted cables in an underground loop. It is a simple, reliable tool that adds capability to the lineman’s existing CHANCE 5/16kV or 16kV phasing sets, allowing immediate cable testing during storms and new construction. The compact size and low cost, compared to other available diagnostic cable testers, allows for multiple trucks to do cable testing without long outages while waiting for more expensive and complicated equipment to arrive on the job site.

The CHANCE® Drivecast™ screw displacement pile underwent three installations in the northeast, each achieving significantly positive test results. 

As a power utility company, it is critical to understand the benefits and challenges when it comes to substation communications IP migration. There can be major benefits when migrating from TDM to packet networks.

Consumer demands for reliable electric power have continued to increase over the years with technological advances. The prevalence of high tech devices has required utilities to provide near uninterrupted service.
