Electrical Distribution Systems

The number of Electrical systems in any Automotive & Off highway vehicles is more complex due to large number of components and requires system integration knowledge. In addition, the weight of the components and harnesses needs to be tracked and optimized in order to keep the cost of harnesses under control. With years of experience TTC provides end to end solution for wiring harness design and development.

TTC has excellent knowhow in benchmarking of wiring harness for localisation purpose, cost reduction purpose and creating best value proposition for the wiring harness system.

  • Study and analysis of Power and grounding strategies
  • Systems functional behaviour study in different power modes
  • Visibility and reachability of the wiring harness components
  • Study and analysis of connectors, splices, fuse boxes, ECU’s, wires etc..
  • Study of packaging – space optimization

TTC has excellent knowhow in RFQ support & BOM creation of wiring harness for quote purpose.

  • MBOM,EBOM generation
  • 2D wiring harness drawing, Manufacturing drawing
  • Component breakdown & Validation

We also supportcustomers on Design Validation Planning from design phase to SOP of product

  • Component level review : Circuit Simulation
  • 3D Routing and packaging : DMU review
  • 3D Routing & Packaging : VLO (Vehicle layout) Review
  • Vehicle level : Fitment Trials ,Supplier Quality Audit

TTC has excellent knowhow in handling Engineering Change Management activity for wiring harness design & development activity.

  • Routing design changes
  • Circuit design changes
  • 2D drawing design changes
  • Analysis of Engineering change request

We do routing & packaging designof wiring harness to meet functional requirements of wiring harness against Standards and best practices like DFA, DFM, DFC, DFS
optimisation reduces the cost of wiring harness by optimising routing & reduction in cable length.

  • Component 3D cad modelling with Electrical qualification
  • Routing & Packaging
  • DMU review
  • 3D wiring harness flattening & Form board drawing creation
  • Fitment drawing creation

We have thorough knowledge in circuit/schematic design and simulation of wiring harness to meet functional requirements of wiring harness like proper and continuous supply from Battery to required load (for e.g lighting system, wiper system, power windows etc..)
We have acquired knowledge to optimise the cost of wiring harness by reducing weight of copper. We use different simulation tools to optimise wire sizes and also thro’ packaging we have reduced the length of wires.

  • Collection of Device Transmittal Information
  • Power Distribution & Fusing strategy
  • Grounding Strategy
  • Fuse & relay, Wire Spec selection
  • Circuit/Schematic Designs for Entire Vehicle all Subsystem
  • Simulation and Design verification of all circuits

We support customers on development phase like prototype manufacturing, assembly and testing phase

  • Proto fitment drawing creation
  • Prototype manufacturing support
  • Testing support – Sub system level, at system level

Suppliers are accessed to make sure their Systems, Processes and equipment’s are capable of delivering OEM desired Quality Standards.
We also support OEM’s and Tier’s for field failure analysis to identify root cause of failure.
