New product: Bushings with paper
free insulation, RIS
RIS share the same benefits as RIP:
• Partial discharge free
• Installation at any angle
• Self-extinguish material;
• no risk of fire
Enhanced with new features:
• Shorter production cycle
• Easier handling for long transportation and storage
• Reduced tan delta and capacitance
• Not affected by humidity
Special test on RIS bushings:
50 000 Cycles -40°C / +50°C
Special test on RIS bushings:
1000 Hours and 100% humidity
