SHTherm® 210 Glide

  • Enamelled round cu.wire, thermo-resistant and self lubricating
  • Insulated with theic-mod. polyesterimide
  • plus polyamid-imide
  • Class 200
Attributes

"SHTherm® 210 GLIDE" is a highly thermo-resistant enamelled copper wire of heat performance class N with a wide range of good and very good quality features. As it is a triple-coat wire its insulation film consists of 3 different coatings on top of one another. These ensure: a very good permanent thermal and overload resistance, excellent resistance to chemical attacks e.g. by alkalines, washing and cleaning agents, impregnating varnishes and resins, sealing compounds, thinners, solvents and refrigerants as well as their vapours, an excellent mechanical abrasion resistance.

The third layer is functionalized regarding best gliding properties and gives excellent windability, high filling factors, high process speeds and reduced dust during winding operation. The very good surface properties lead to reduced stress on the wire during processing.
In combination with aluminium wires this property gives additional benefits. Compatibility with common resins have to be proofed individually. Reduced mechanical force during winding. The reduced coefficient of friction prevents damage to the wire during winding and thus maintains the insulation properties of the wire.

Index

(1) Due to the variety of individual applications we cannot make any generally binding commitments regarding the compatibility. We recommend testing compatibility with the materials being used.

 
Temperature index (TI) The temperature index is a dimensionless value and represents the long term thermal resistance or the admissible ageing temperature of the enamelled magnet wire in °C for an extrapolated life span of 20,000 h. The temperature index does not necessarily correspond to the thermal class.
 
Thermal class

Enamelled magnet wire according to IEC 60317-.. or DIN EN 60317-... are to be rated as Class X, if

(a) their long term thermal performance demonstrably proves an extrapolated life span of 20,000 h at an ageing temperature of min. X °C (tests preferably to be made on enamelled magnet wires with a nominal diameter of 1.00 mm Grade 2) and

(b) the heat shock resistance complies with temperatures of 25 or 20°C above the rated thermal class.
