1. It is small, but it keeps the exact distance between staked winding discs and is used to cool the winding by securing oil path between copper wires.
2. It withstands the constant mechanical load caused by clamping forces and extreme electrodynamic load caused by a short circuit.
3. It can sustain a rapid rise in temperature due to high operating temperature and overload.
