  2. Transformer oil - Wikipedia

    en.wikipedia.org/wiki/Transformer_oil

    Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. It is used in oil-filled wet transformers, [1] some types of high-voltage capacitors, fluorescent lamp ballasts, and some types of high-voltage switches and circuit breakers. Its functions are to insulate, suppress ...

  3. Insulation system - Wikipedia

    en.wikipedia.org/wiki/Insulation_system

    Insulation system. The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification.

  4. IP code - Wikipedia

    en.wikipedia.org/wiki/IP_Code

    The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 [1] which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures ...

  5. SAE J300 - Wikipedia

    en.wikipedia.org/wiki/SAE_J300

    SAE J300 is a standard that defines the viscometric properties of mono- and multigrade engine oils, maintained by SAE International. [1] Key parameters for engine oil viscometrics are the oil's kinematic viscosity, its high temperature-high shear viscosity measured by the tapered bearing simulator, and low temperature properties measured by the ...

    IEC 60642 Piezoelectric ceramic resonator units. IEC 60644 Specification for high-voltage fuse-links for motor circuit applications. IEC 60645 Electroacoustics – Audiometric equipment. IEC 60648 Method of test for coefficients of friction of plastic film and sheeting for use as electrical insulation.

  7. Motor oil - Wikipedia

    en.wikipedia.org/wiki/Motor_oil

    Motor oil is a lubricant used in internal combustion engines, which power cars, motorcycles, lawnmowers, engine-generators, and many other machines. In engines, there are parts which move against each other, and the friction between the parts wastes otherwise useful power by converting kinetic energy into heat.

    A ZQDR-410 traction motor (the large, dark component on the axle with small ventilation holes) A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric or hydrogen vehicles, or electric multiple unit trains. Traction motors are used in electrically powered railway vehicles ( electric multiple units ...

  9. JASO M345 - Wikipedia

    en.wikipedia.org/wiki/JASO_M345

    JASO M345 is a quality classification standard for two stroke engine oils for engines of Japanese origin. It was introduced by the Japanese Automotive Standards Organization (JASO) in 1994 as JASO M345-93 with the quality levels JASO FA, JASO FB and JASO FC – with FC setting the highest standard. It was revised in 2004 as JASO M345:2004 which ...
