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 $ire is a insulated conductor used to carr"
electricit"
What is a Electrical Cable/ Budle?
% cable is two or more wires running side b" side and bonded, twisted
or braided together to form a single assembl".
!r"tecti#e C"#eri$s%There are two t"pes of protectie coerings to the harness.&. 'rotectie tape
2. 'rotectie corrugated tube.'rotectie coerings are instantiated from an electrical catalog. (" default,
the protectiecoering will coer the entire bundle segment, howeer, it can be ad)usted to coer
)ustparticular segments.

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
deices.
