Winding wire SHTherm^® V180

Enamelled round cu. wire
Insulated with polyesterimide
Solderable
Class 180

"SHTherm^® V180" is a thermo-resistant, self-fluxing enamelled copper wire of thermal performance class H which, at solder bath temperatures from 465 °C upwards, provides the possibility of contacting without prior removal of the insulation film. This coating shows good thermo-resistance and chemical compatibility with commercial impregnating agents, impregnating varnishes, extrusion-coating agents, sealing compounds, solvents and detergents. Sophisticated process technology and process setting ensure easy mouldability, very good elongation properties and low coefficients of friction as well as good and constant dielectric insulation properties of these wires.Thanks to this "SHTherm^® V180" is ideally suited for processing on highspeed, sophisticated winding machines. Enamelled copper wires of this type can also be welded and mechanically connected.

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.
