SynCon® – Connecting Cables & Transformer Terminals Single Core Conductor BETAtherm® 155 UL/cUL (metric)

BETAtherm® 155 UL/cUL 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/cUL 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/cUL 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-rating 150 °C)
  • RoHS compliant according to 2011/65 EC
  • UL AWM Style 3289, cUL CL 1503

Conductor

Tinned copper wire VDE 0295/ IEC 60228 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.
