SynCon® – Connecting Cables & Transformer Terminals Single Core Conductor BETAtherm® 145 halogen free (UL 3271/CSA;UL 3820/cUL)

BETAtherm® 145 UL is a flexible low-voltage cable with UL recognition consisting of a tinned copper stranded wire and insulated with coloured electron-beam crosslinked polyolefine copolymer.

Due to its electron-beam cross-linked insulation BETAtherm® 145 UL achieves extremely high - still class B - thermal resistance. This results in excellent thermal resistance. However, it cannot even be melted at elevated temperatures and has thus to be skinned during processing. Skinning is simple and also possible at machines. BETAtherm® cables are resistant to all common insulating varnishes. They are halogen free and flame retardant.

Conductor

Tinned copper wire VDE 0295/ IEC 60228 class 5.

The dimensions specified in the checklist are regarded as standard values. The actual cross sections may vary. The cables are manufactured according to European standards with a metric conductor cross section, AWG sizes are approximate values and vice-versa. Always observe relevant standards valid for divergent operating conditions when laying for greater limit current loads.
