Baygal®/Baymidur® casting resin systems containing mineral fillers have been used for more than 35 years for high-grade solid insulation in current and voltage transformers.
Polyurethane systems for solid insulation are processed by vacuum gelation and pressure gelation in two-component casting machines.
|These polyurethane casting resins have proven themselves with:|
- high electrical resistance up to 70 kV
- excellent dynamic characteristics
- high accuracy through low shrinkage
- excellent durability
- low production costs
- compatibility with other insulating materials (paper, rubber, SF6, etc.)
The choice of process depends on criteria such as the type of transformer and the number required, and the same machine may be used for both processes.
