By use of oil insulation and porcelain bushings, such transformers can be applied at the highest transmission voltages. [1] Zero-phase-sequence current transformer. Ring-type current transformers are installed over a bus bar or an insulated cable and have only a low level of insulation on the secondary coil.
Oil Well Pump Motors – Severe Duty Motors – Pool Pump Motors – One of the quietest motor pump on the market, due to its permanent magnet motor and TEFC design; Compare to the ODP (Open Drip Proof) motor design, which has ventilation openings which are guarded to prevent falling water from entering the motor windings.

Nissan GT-R debut at the 2007 Tokyo Motor Show. The production version of the GT-R was unveiled at the 2007 Tokyo Motor Show as confirmed, following an on-screen 7:38.54 minute lap time in damp conditions around the Nürburgring Nordschleife was broadcast, beating the benchmark Porsche 911 Turbo's time of 7:40 minutes. Nissan called it the ...
Since the 1965s, resin materials have been used for all types of bushing up to the highest voltages. The flexibility of using a castable form of insulation has replaced paper insulation in many product areas and dominates the existing insulated bushing market. As with paper insulation, the control of electric stress fields remains important.
Fuel oils include heavy fuel oil (bunker fuel), marine fuel oil (MFO), furnace oil (FO), gas oil (gasoil), heating oils (such as home heating oil), diesel fuel, and others. The term fuel oil generally includes any liquid fuel that is burned in a furnace or boiler to generate heat ( heating oils ), or used in an engine to generate power (as ...

Plastic film capacitors potted in rectangular casings, or dipped in epoxy lacquer coating (red color) Film capacitors, plastic film capacitors, film dielectric capacitors, or polymer film capacitors, generically called film caps as well as power film capacitors, are electrical capacitors with an insulating plastic film as the dielectric, sometimes combined with paper as carrier of the electrodes.
