1 Description Properties BETAtherm 155 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 155 UL achieves a special thermal resistance required for Class F. This results in excellent thermal resistance. However, it cannot even be melted at elevated temperatures and has to be skinned during processing. Skinning is simple and also possible at machines. BETAtherm cables are resistant to all common insulating varnishes. They are flame retardant. Application BETAtherm 155 UL is suitable for the internal wiring of electric machines, lamps, heating appliances, as well as for application in apparatus, mechanical and plant engineering. Due to the high thermal load capacity, it might be possible to reduce the conductor cross section and, therefore, save space and reduce the weight. Standards Thermal class F (155 C) UL AWM Style 3289 and CSA CL 1503 RoHS compliant according to 2002/95 EC

2 Conductor Tinned copper wire VDE 0295/ IEC class 5. The dimensions specified in the technical datasheet 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 viceversa. Always observe relevant standards valid for divergent operating conditions when laying for greater limit current loads. Colour Delivery format Green/yellow, black, light blue, dark blue, brown, red, white, grey, violet, orange, yellow, green. Other colours, also two colours, available on request.
