    ELECTRICAL WIRE HARNESS DESIGN

    Why WIRE HARNESS is required?

    The total length of wires can be as much as 3 to 4 km in a car, 600 kmin an aircraft, while the total cable length in a cruise ship can reach up to 2500 km.

    the weight of the components and harnesses needs to be tracked and optimized in

    order to keep the cost of harnesses under control. This

    integrated enironment improes design !ualit", drasticall" reduces time needed

    for modifications and minimizes errors, leading to optimizing the costs.

    What is Electrical Wire?

    #lectrical $ire is a insulated conductor used to carr"

    electricit"

    What is a Electrical Cable/ Budle?

    % cable is two or more wires running side b" side and bonded, twisted

    or braided together to form a single assembl".

    ELB%#-( allows users to create and manage catalogues containing

    electrical components. This product etends mechanical parts and assemblies

    with electrical behaiors to define electrical components, such as connectors,

    e!uipments, shells, supports and protections. These deices can be stored incatalogues in the same wa" as mechanical 1%T*% ?5 parts@assemblies. $hen the

    components are placed from the catalogue in the =9, it takes into account all

    preAdefined mechanical constraints, this allowing a 1orrect use@placement of the
