A flat cable comprises a series of parallel electrical conductors (1 to 6) each carrying a spiral-wound tape insulation layer (30). The conductors are held together by braiding formed of a plurality of tapes (10 to 22) or fibres interwoven between the conductors. The braiding is preferably of a thermoplastic material which may be heat bonded to the insulation in order to set the cable in a desired shape e.g. for a wiring loom. The insulation and braiding is preferably formed from a mixture of polytetrafluoroethylene (PTFE) and a copolymer of tetrafluoroethylene and perfluoro(propylvinylether).

Why it's free to use
- Filed March 29, 1993 and granted May 21, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 29, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 29, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
