Insulated round cooper wire wrapped twice with glass silk (2SS)Type 2SS(SRPS N.C7.120) Thermal grade F and H |
Insulated round copper wire consists of a soft annealed copper wire wrapped twice by glass filament and polished by two layers of baked silicon enamel. Constructive-technical data are given in the table below and it is possible to produce inter-dimension in the interval from 0,50 to 3,20, changing diameter for 0,1mm.
The conductors are applied for various winding at electrical motors and transformers operating under higher temperature conditions. Class F:155° C permanent , class H:180° C permanent.
In coils or according to customers wish.
