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.

2014 Land Rover Dicovery 5 to lose more weight than 2013 Range Rover
Mon, 17 Sep 2012It appears the next generation Land Rover Discovery is set to shed even more weight that the latest 2013 Range Rover. We know that Land Rover are on a quest to reduce the weight of their offerings, and the all aluminium 2013 Range Rover is the first real evidence with weight drops of up to 420kg for the new 3.0 litre diesel. But it looks like the next generation Land Rover Discovery – which is due in 2014 and will be the Discovery 5 – is going to eclipse even the huge weight loss of the new Range Rover.
Infiniti making noise about its new M35 hybrid
Fri, 19 Nov 2010Infiniti has just announced that its new M35h will be the world's first hybrid with a standard audible pedestrian warning system to alert pedestrians when the car is running silently on EV mode. Infiniti calls the system VSP, or 'Approaching vehicle sound for pedestrians'. It uses a range of distinctive sounds to alert pedestrians via a speaker built in to the front bumper. Instead of reproducing the sound of an internal combustion engine, the Infiniti produces a range of beeps.
Indiana yanks Kruse auction licenses
Wed, 26 May 2010Kruse Inc., the auction company that sold the famous William Harrah car collection and has been synonymous with auctioning enthusiast automobiles since the 1970s, has lost its licenses in its home state. The Indiana Auctioneer Commission ruled on Tuesday to revoke both of Kruse Inc.'s licenses, and the company has to wait seven years to apply for new ones, said Kelly Butters, a spokeswoman for the Indiana Attorney General's Office. Dean Kruse, president of the auction house, has had his personal license suspended indefinitely.
