Conductive Polyester Electrifeutre® (F)
- 100% Polyester fibres.
- Fibres assembled by thermowelding without binder.
- Coated with a class F resin charged with conductive products, which gives the tape a superficial determined and regular resist ance.
- The FR references are made of with renforcement yarns lengthway to have a good breaking resistance.
- CABLES :
This tape is used on the conductor in order to by-pass vacuums.
- ROTATING MACHINES :
For rotating machines of medium voltages from 1 to 16KV, it is recommend to use conductive products (paint, tape, etc.).
This tape is particularly suitable for both under vacuum and pressure impregnation systems. Partial (bobbins or bars only). Global (bobbins sets and magnetic circuits). The tape is used on straight parts of bars or sections and is compressed simultaneously with the mica insulation.It brings their surface at the same electrical level ( equipotential surface ) in order to absorb the electricity created by the electrical field of the rotor, which avoids sparks (brusch discharges). This tape allows to improve the measure of the dispersal factor (delta tangent).
- USE OF PAINTS AND THEIR DISADVANTAGES.
The applied thickness is irregular.
Risks for hygiene and security. They settle in the pots.
Varying concentration during its appliction.
