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.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
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.
