Copper Fittings Dimensions

Leoni reduces weight of vehicle's cables by 3kg

Of the roughly 3,000 meters of cable that today’s motor vehicles contain, the connection between the battery and the engine is one of the bulkiest single cables. The potential for saving weight on this component is all the greater when the battery is located in the rear of the vehicle. Leoni has therefore replaced the copper battery cable with a round aluminium busbar, which can be fitted directly on or underneath the vehicle’s chassis. It has a variable diameter depending on the application and is insulated with a halogen-free polyethylene jacket. Depending on the type of vehicle, it can have a length of more than four metres and be deployed in either a single or twin track version.

Leoni showed this new aluminium busbar at the IAA International Motor Show in Frankfurt recently. It weighs just 40 to 60% as much as traditional copper cable. The saving is made possible by the fact that aluminium has significantly less specific gravity than copper. In absolute terms, the weight saving can be up to three kilograms, which contributes to lowering CO emissions.

Aluminium conductors would normally necessitate an increased diameter, but Leoni says this can be avoided since solid structure and a special manufacturing facility considerably reduce the busbar’s diameter. Compared with a multi-core copper cable with a 15.5 millimetre diameter, the aluminium busbar of identical conductivity has a diameter of less than 14 millimetres. The technology thus also helps to address the issue of diminishing installation space.

To ensure a perfect fit to the vehicle’s chassis, the busbar is designed CAD-controlled in a three-dimensional space. Its round shape makes continuous bending in all directions easily possible; something that other solutions available on the market do not permit. This facilitates inside bend radii that are no larger than the bar’s diameter.

Handling the rigid busbar is easier than is the case with a limp cable. The carmaker thereby saves time on installing in the vehicle. The component is connected at both ends by means of a clever but easy to operate fitting system and in between fixed to the chassis with special brackets.

Usage of PEX Fittings For PEX Tubing Installation | Industrial ...

Units used to link up flexible cross linked polyethylene pipes used in diverse plumbing water schemes are called as PEX fittings. Since, PEX tubes have emerged as cost effective and trouble free alternatives to copper and plastic tubes and pipes, so they need similar efficient fittings. Freedom from troubles of corrosion and scaling can be easily achieved through these fittings. An arrangement of PEX fittings with PEX tubing has emerged as a brilliant alternative to traditional methods of water plumbing.

PEX tubes require fewer fittings as they involve less breakages and leakages. As compared to earlier rigid and tough plumbing units, PEX fittings are more flexible and durable units. Since these fittings do not involve soldering, there are no risks of nasty fumes attached with them. Tubing used for plumbing are weaved in reels as it is cost efficient and easy to use because of their reduced weight and warehousing space. In comparison to other types of tubes, PEX tubing involves less shipment cost. Some of the PEX tubing can be directly installed by using fewer fittings. Such fittings are composed of highly durable form of brass and copper so that they can be used for delivering long lasting benefits.

Installation of PEX tubing with these fittings is very easy and simple. It is done by inserting a PEX tube fitting over a pipe or tube and then by pinching a copper ring. Apart from this, there are other simple methods also, which are used for making connections and joints.
