Hello Gary, A quick check on our website shows that the largest cable we stock is 16mm2 with a current rating of 91A continuous. Assuming your application is for combat robots, 16mm2 is quite commonly used for the main battery leads with peak current demands of over 200A. Large cables are also not too flexible although specialist types are available. Personally I prefer to use multiple cables in parallel of a smaller cross sectional area. I use three 6mm2 cables in parallel with an effective current rating of 159A continuous which can easily cope with peak current demands of well over 200A. Ideally do not bunch multiple parallel cables to achieve maximum heat dissipation to the surrounding air. Bunching will result in the cable rating being derated but for short high current demands, you may well find this not to be an issue. |
