Which wire connectors are safe?
Wired.com, June 26, 2018 — The wire connectors used to connect the wires that power your home, car, and other devices are more vulnerable to damage than previously thought, according to a new study from the University of California, Berkeley.
The study found that a high-voltage wire can bend or crack if it gets hit by an object such as a hammer or a screwdriver.
The study also found that the same type of wire can fail at a different rate than a similar type of high-quality, high-frequency wire, according.
“A high-strength wire, like an AC power line, can bend if it’s struck by a hammer,” said study co-author Matthew G. Hirsch, professor of electrical engineering and computer science at UC Berkeley.
“But the same high-end quality, high frequency wire can break when it’s touched by a screw driver.
So, the risk is a little bit higher with high-value wire.”
The researchers looked at the characteristics of 12 types of high quality wire, and then used computer modeling to estimate the risk of failure.
The wire is designed to last for a few years before it’s replaced, but a lot of that time could be spent inside a home, a garage, or a utility box, according the study.
Researchers tested the reliability of each type of copper wire by measuring the electrical resistance of each wire and then comparing that resistance with that of a standard wire, which was measured in a lab.
The scientists found that high-wire types that are designed for high-power applications tend to be more prone to failure than their low-wire counterparts.
The researchers also tested a variety of high wire types, including high-speed wire, high voltage wire, copper wire, flexible wire, ribbon wire, electrical tape, and wire connectors.
High-strength, high speed, high velocity, and ribbon wires are the highest quality wire used in home and automotive applications, according G. Michael Miller, vice president of research and product management at U.S. Power & Light.
Miller said that a single piece of high performance, high energy wire is about 1,000 times more expensive than a standard high-tech wire.
In addition, high quality, long-life copper wire is more durable than other high-energy types of wire, Miller said.
“High-quality wire is a long-lasting conductor that’s very good at protecting against corrosion and it’s also relatively inexpensive,” he said.
The researchers found that wire that is made of high energy is much more prone than other wire to fail when exposed to a variety.
Most of the high-grade wire that has been tested was made of polyethylene or polypropylene, which can bend.
However, the researchers found the majority of the other high quality products tested had aluminum, nickel, or copper inclusions.
High-end polypropylene is the most commonly used type of polycarbonate, but researchers have also found other high performance polyethylenes such as polypropanol, polyurethane, and polystyrene.
The University of Michigan said that the study’s findings will be useful in designing more effective home and car wiring that can withstand the elements.
The U.K. Telegraph reported that the University College London is planning to launch a new research and development centre dedicated to high-performance high-density copper wire.
