Harness Design Considerations
For client information, some factors
which have to be considered when designing a harness are listed below. The
list may be useful when considering your own harness requirements.
Component considerations:
- Electrical requirements
- Mechanical considerations
- Quality requirements
- Reliability
- Design redundancy (contact count)
- Connector selection (type and form)
- Locking requirements
- Backpotting requirements
- Waterblocking in mouldings
- Cable specification
- Cable jacket material and compatibility with elastomers
- Abrasion resistance
- Stiffness profile at termination
- Connector format (straight or right angle)
- Moulding format (straight or at an angle)
- Clearance allowance for moulding and cable trajectory
- Elastomer compatibility (eg oil filled units)
- Metalwork selection re: corrosion and EC compatibility
- Surface finish for metalwork as appropriate.
- Operating depth profile (not just max. depth)
- Tensile loads
- Torsional loads
- Bending loads
- Bend control requirements (to limit bending at termination)
- Deployment and recovery loads
- Dynamic loading
- Flow turbulence effects.
