2. Electrostatic discharge materials - Wikipedia

   en.wikipedia.org/wiki/Electrostatic_discharge...

   Insulative materials prevent or limit the flow of electrons across their surface or through their volume. Insulative materials have a high electrical resistance and are difficult to ground, thus are not ESD materials. Static charges remain in place on these materials for a very long time.

3. List of IEC standards - Wikipedia

   IEC TS 61934 Electrical insulating materials and systems – Electrical measurement of partial discharges (PD) under short rise time and repetitive voltage impulses; IEC 61935 Specification for the testing of balanced and coaxial information technology cabling; IEC 61936 Power installations exceeding 1 kV a.c.

4. List of welding processes - Wikipedia

   en.wikipedia.org/wiki/List_of_welding_processes

   Following an electrical discharge, pressure is applied which forges the materials together Components of switch gear devices Thermite welding: 71: TW Exothermic reaction between aluminium powder and iron oxide powder Railway tracks Electrogas welding: 73: Continuous consumable electrode, vertical positioning, steel only Storage tanks, shipbuilding

5. Shielded metal arc welding - Wikipedia

   en.wikipedia.org/wiki/Shielded_metal_arc_welding

   An electric current, in the form of either alternating current or direct current from a welding power supply, is used to form an electric arc between the electrode and the metals to be joined. The workpiece and the electrode melts forming a pool of molten metal ( weld pool ) that cools to form a joint.

6. Electromaterials - Wikipedia

   en.wikipedia.org/wiki/Electromaterials

   Electromaterials enable the transport of charged species (electrons and/or ions) as well as facilitate the exchange of charge to other materials.For atomic and molecule systems, this is observed as atomic electronic transition between discrete orbitals, while for bulk semiconductor materials electronic bands determine which transitions may occur.

7. List of insulation materials - Wikipedia

   en.wikipedia.org/wiki/List_of_insulation_materials

   This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.
