Winding wire SHSold® V155
- Solderable enamelled round cu.wire
- Insulated with polyurethane
- Class 155
SHSold® V155 is a self-fluxing enamelled copper wire of thermal performance class F. The most outstanding characteristic of this wire is the possibilty of having an efficient and safe contact of the wire ends by fast and easy solderability with a solder bath temperature from 390 °C upwards without prior mechanical removal of the insulation film. This type of enamelled copper wire fulfills the requirements of modern winding technology. In accordance with the manufacturer's instructions SHSold® V155 can be impregnated and cast with compounds. Chemical resistance to aggressive, liquid or gaseous mediums is limited, and therefore we recommend that you carry out compatibility tests before using this enamelled copper wire. SHSold® V155 can be easily welded and mechanically connected. Sophisticated process technology and process setting ensure easy mouldability, best elongation plus constant and good insulation characteristics of these wires.
