Copper Cables; Aluminum Cables? There’s Something Much
Better: Copper-Clad Aluminum! In the 1970’s Piper Aircraft thought they had a better idea and sold lots of small airplanes with aluminum high-current wiring. Years later they sheepishly issued Service Bulletins 836 and 836A to remove this wiring and change it back to copper. This happened around the same time the housing industry was regretting all the aluminum wiring they had put into houses when the houses started to burn down. But hold on a second! The only problem Piper had was a plague of poor-starting troubles. There was one wire/fire accident, but its cause is still in doubt. The housing industry’s problem was that they used aluminum wire with connection hardware designed for copper. Aluminum is used everywhere in the electrical industry.
Motors are wound with it, high-voltage lines are made with it, and the drop
from the power line to your house’s circuit breaker box is aluminum.
Given the weight of wiring in an airplane or racecar, aluminum looks like a good way to save weight, but it represents some compromises—Aluminum is much harder to work with than copper. Furthermore, low-voltage wiring is particularly tricky with aluminum. Power companies have to strengthen aluminum high-voltage cables that hang from transmission towers with steel wire. Special connectors are required. Special goops are necessary to prevent corrosion at joints, and sometimes the outside of the aluminum must be coated, plated or anodized to make its surface behave. There is still a long history of problems with aluminum wire, and a lot of engineers spend their careers trying to solve the problems. But the ideal solution is to make a wire that is copper on the outside and aluminum on the inside. This is like packaging the aluminum inside copper tubing. The wire has the low-corrosion characteristics and great solderability of copper but possesses the high-conductivity-per-mass of aluminum, resulting in a huge weight savings. This is NOT copper-plated. The copper outsides are fused on before the wire is drawn. The resulting cable is a little fatter but much lighter. If you replace 4 AWG copper with Super-4-CCA, you save over one-ounce per foot compared to copper. Remember composite vehicles need a ground cable too. FACT: A long problem-history exists using plain aluminum wire, but there is no problem-history with Copper-clad-aluminum (CCA) wire at all. Installation: CCA can be treated exactly like copper, it
crimps almost the same and it solders even easier. The cable is more expensive due the small production runs, but the big airplane guys like Airbus and Boeing use this stuff by the mile. Unfortunately, they won’t sell you any. (The Super-4-CCA uses common AWG 2 lugs. (Shown but not supplied). Applications we sell to:
We also make custom sizes with specified insulation if you can buy a minimum of only 500 feet. Delivery time is usually only 3-4 weeks.

Ferrari 599 GTB 60F1 (2011) first official pictures
Thu, 08 Dec 2011Ferrari is launching a special pack of paint and trim options on the 599, called the 599 GTB 60F1. It's designed to mark six decades of winning in Formula 1 (not something the scuderia has done much of in 2011). Froilan Gonzalez won Ferrari's first F1 race in the 375 F1 car back in July 1951; 60 years later, Fernando Alonso won Ferrari's first race of the current season in the 150° Italia.
Nissan Townpod concept preview
Thu, 09 Sep 2010Nissan has just released this image of its new Townpod concept, which offers insight into how the brand could expand its portfolio of zero-emission vehicles. It will be displayed at the Paris motor show. Designed to offer zero-emissions mobility to a future generation of home-based, innovative entrepreneurs who are creative and tech-savvy, the Townpod "combines eye-catching design with a spacious and practical interior," Nissan says. "[It's] more than just a car and it's more than just a van – it heralds a new-era of flexible, stylish vehicles that will bring electric-vehicle mobility to the masses." We'll bring you more information, our critique of the design and our own unique photographs of the Townpod in a few weeks' time.
Not every Chrysler dealer gets to sell SRT Viper
Mon, 23 Jul 2012The redesigned 2013 SRT Viper will be sold at about one in five Chrysler Group dealerships, says Ralph Gilles, head of the high-performance SRT brand. To qualify for the sports car, dealerships will have to train staff, buy special tools and improve their facilities. "We're going to open it up to any dealer who can put the money forward and the training, but it's going to be pretty difficult to hit all of those things," Gilles said during a broadcast interview with journalists in Detroit this month.
