Alpha Wire's solar
cables and photovoltaic wire are designed for the harsh environments of
solar energy applications-the hot and cold of climate extremes, ozone and UV
radiation, moisture, oil and direct burial. The cables use a specially
formulated PVC jacket that can withstand the potential environments without
failing or degrading.
Available in a wire range from 14 to 2 AWG, the photovoltaic wires come
in two versions to meet either UL 4703 PV wire/TUV Pfg 1169 requirements or
UL 4703 PV wire requirements. UL 4703
PV wire/TUV photovoltaic wires are made with low-smoke, zero-halogen (LSZH)
materials which do not emit toxic gases when burned. The UL PV wire products
use a cross-linked polyethylene insulation and PVC jacket.
cables, in sizes from 18 to 12 AWG and conductor counts from 3 to 9, are
available shielded or unshielded. The
TC-ER and MTW-rated cables have an abrasion-resistant jacket.
the PV wire and solar cable are designed specifically for solar environments-they
are sunlight and oil resistant and withstand temperatures from -40 to +90C. The solar cables meet requirements for
direct burial without conduit.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
