The RIF® Advantages: the new state of the art in HV Bushings

Built on the proven concept of finely graded condenser insulations, our high voltage transformer bushings' patented core insulation is composed of fiberglass impregnated with epoxy resin cleverly layered between capacitance screens while the outer insulation is exclusively featuring silicone rubber, compounding a uniquely stress-free core insulation with superior pollution and climate resistance.

Introduced in 2002 with immediate success, RIF® bushings have triggered a whole new phase of high voltage bushing technology in the industry.

Those proprietary RIF® bushings also differ from oil (OIP) or resin impregnated paper (RIP) bushings by the fact that they don't feature any gap or open cavity in their structure. They are totally solid and dry.

As a result, there isn't any interstitial insulating filler in any open space between capacitive cores and outer insulators. Freed from critical seals the insulation configuration is then better waterproofed by design and related manufacturing processes are much simplified. This simplicity translates into robustness, reliability, safety and shorter lead times.

Consequently the RIF® technology delivers four major improvements:

1. A totally dry type condenser structure with superior electrical performance and a uniform
   electrical field profile along the bushing
2. Long-term sustainability of performance under multidimensional operational stresses
3. A remarkable resistance to mechanical and seismic shocks as well as thermal stresses
4. A core insulation condition that can be monitored in real time thanks to a unique and safe
   built-in low voltage test tap feature (option)

This provides our customers with key benefits:

		Long term steady operation with very low and consistently stable PD and tanδ values
		Discretionary maintenance, explosion-free and environmentally-friendly operation in extreme operational conditions (thermal, climatic, pollution, mechanical) for long term reliability, lower cost of ownership and increased transformer reliability and uptime
		Lower spare parts inventory thanks to shorter lead times combined with higher reliability
		Strengthened protection of assets by leveraging smart bushings that can continuously monitor the insulation's condition thus protecting host power transformer from critical damage that would be generated by a failing bushing

All products are developed and manufactured in an ISO 9001 certified plant. Quality is central to all aspects of our technologies and processes.

In short, the RIF® technology uniquely reduces risks for power transformer operators along with their total costs of ownership. Available up to 300kV.
