Why RIP Condenser Bushings are Essential for Modern Transformers?

What are RIP Condenser Bushings?

RIP bushings are dry type of transformer bushings. In RIP bushings, the condenser is formed by use of coaxial conducting layers around the central conductor at specified radial intervals. These coaxial conducting layers comprise of thin aluminum foils and electrical grade insulating crepe papers. The configuration aids in uniformly distributing the electric field (radially and axially) over the bushing insulation systems.

The core is then subjected to heat and vacuum application before impregnation with special resins for electrical uses, hence an entirely dry and oil-free active part solution.

The active component is assembled using hollow silicone insulators or direct-molded silicon, along with mounting flanges and other metal parts. This careful assembly leads to bushings that surpass their OIP counterparts in several main areas.

Why are RIP bushings critical for modern transformers?

1. Oil-free / Partial discharge-free

One such excellent feature of the RIP bushings is their oil-free design. Since these types of bushings do not have any oil, they evade the hazardous leakage of oil, which may lead to much operational danger. Also, RIP bushings are partial discharges that offer an extended life and stronger performance efficiency. Such advantages lead to the minimum amount of maintenance and safety of the transformer.

2. Non-flammable, Self-extinguishing

The RIP bushings are self-extinguishing when exposed to open flames and inherently not flammable. The bushings can be used on transformers located in high-risk settings or within areas having very strict fire safety settings.

3. Outstanding seismic performance

RIP bushings can be used by transformers operating in areas prone to earthquakes, as they perform well in seismic applications. As such, these bushings have been designed to withstand severe mechanical stresses, ensuring that a transformer does not fail under extreme conditions. This capability is crucial in keeping downtime low and grid stability in natural disasters such as floods.

4. High thermal strength

Due to their high thermal strength, RIP bushings can be operated efficiently at temperatures up to 120°C. Therefore, the characteristic enables survival within adverse environmental conditions without forming a performance problem and thus is considered a reliable choice for transformers subjected to fluctuations or heightened temperatures.

5. Lightweight and Compact

The most important advantage of RIP bushings is that they are mechanically rigid but light in weight. In fact, they are 50% lighter than corresponding OIP bushings for the same voltage rating, current rating and CT space. This reduction in weight reduces transportation, storage, and installation logistic costs while helping to simplify transformer setup.

6. Flexible installation

Another strange advantage with RIP bushings is they permit flexibility in installation. Unlike other bushing types, RIP bushings are portable, storable, and can be installed horizontally or at any angle without negative impact on their performance. This also means a transformer fitted with RIP bushings can be energized immediately after installation, further reducing downtime associated with installation or any procedures that may be performed.

7. Reduced downtime for major failures

When a major failure occurs for the transformer, the cost of downtime can be costly, but RIP bushings seal the transformer very well, reducing time spent idle and from further potential damage.

8. Shatter-proof, Hydrophobic silicone sheds

Hydrophobic silicon sheds on usage ensure that the bushings are RIP and break proof, with water-proof properties. Water generally rolls off from hydrophobic properties that reduce the chance of contamination and thus give a longer-term reliability especially in a moist or wet environment. This enhances the durability and low-maintenance attributes of the bushings.
