  2. Dielectric strength - Wikipedia

    en.wikipedia.org/wiki/Dielectric_strength

    The field strength at which break down occurs is an intrinsic property of the material called its dielectric strength. In practical electric circuits electrical breakdown is often an unwanted occurrence, a failure of insulating material causing a short circuit , resulting in a catastrophic failure of the equipment.

  3. IEC 60228 - Wikipedia

    en.wikipedia.org/wiki/IEC_60228

    Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...

  4. Copper conductor - Wikipedia

    en.wikipedia.org/wiki/Copper_conductor

    The tensile strength of a material is the maximum amount of tensile stress it can take before breaking. Copper's higher tensile strength (200–250 N/mm 2 annealed) compared to aluminium (100 N/mm 2 for typical conductor alloys [ 16 ] ) is another reason why copper is used extensively in the building industry.

  5. Electrical breakdown - Wikipedia

    en.wikipedia.org/wiki/Electrical_breakdown

    Electrical breakdown in an electric discharge showing the ribbon-like plasma filaments from a Tesla coil.. In electronics, electrical breakdown or dielectric breakdown is a process that occurs when an electrically insulating material (a dielectric), subjected to a high enough voltage, suddenly becomes a conductor and current flows through it.

  6. Aluminium-conductor steel-reinforced cable - Wikipedia

    en.wikipedia.org/wiki/Aluminium-conductor_steel...

    Many electrical circuits are longer than the length of conductor which can be contained on one reel. As a result, splicing is often necessary to join conductors to provide the desired length. It is important that the splice not be the weak link. A splice (joint) must have high physical strength along with a high electrical current rating.

  7. International Annealed Copper Standard - Wikipedia

    en.wikipedia.org/wiki/International_Annealed...

    A measurement of the electric conductivity of aluminum alloys can be used to verify that a heat treatment process has been done correctly. For example a component made of "7075" alloy which was correctly treated with the process "T73" to gain resistance to stress corrosion cracking will fall in the range of 38.0 to 43.0 % IACS.

  8. Electrical resistivity and conductivity - Wikipedia

    en.wikipedia.org/wiki/Electrical_resistivity_and...

    The mechanism is similar to transfer of momentum of balls in a Newton's cradle [11] but the rapid propagation of an electric energy along a wire is not due to the mechanical forces, but the propagation of an energy-carrying electromagnetic field guided by the wire. Most metals have electrical resistance.

  9. List of IEC standards - Wikipedia

    en.wikipedia.org/wiki/List_of_IEC_standards

    IEC 60243 Electric strength of insulating materials; IEC 60244 Methods of measurement for radio transmitters; IEC 60245 Rubber insulated cables – Rated voltages up to and including 450/750 V; IEC 60246 Connecting wires having a rated voltage of 20 kV and 25 kV d.c. and a maximum working temperature of 105 °C for use in television receivers
