FeaturesThe main feature of this class F wire is the ability to weld the end at tin bath temperatures from 375°C, without the need to mechanically remove the varnish layer. Structurally it consists of a single POLYURETHANE varnish.
It is compatible with commercial encapsulation and impregnation systems, although chemical resistance is limited and therefore compatibility testing is recommended for confirmation. |
