2. Nickel–metal hydride battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–metal_hydride_battery

   H 2 O + M + e − ⇌ OH − + MH. On the positive electrode, nickel oxyhydroxide, NiO(OH), is formed: Ni(OH) 2 + OH − ⇌ NiO(OH) + H 2 O + e −. The reactions proceed left to right during charge and the opposite during discharge. The metal M in the negative electrode of a NiMH cell is an intermetallic compound. Many different compounds ...

3. Building insulation - Wikipedia

   en.wikipedia.org/wiki/Building_insulation

   If the renovation is of a smaller nature, the renovation directive applies. Examples of renovation are post-insulation of a cavity wall and post-insulation of a sloping roof against the roof boarding or under the tiles. Note that every renovation must meet the minimum Rc value of 1.3 W/(m 2 ⋅K). If the current insulation has a higher ...

4. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   Insulation is a barrier material to resist/reduce substance (water, vapor, etc. ) /energy (sound, heat, electric, etc.) to transfer from one side to another. Heat/ Thermal Insulation is a barrier material to resist / block / reflect the heat energy (either one or more of the Conduction, Convection or Radiation) to transfer from one side to another.

5. Appliance classes - Wikipedia

   en.wikipedia.org/wiki/Appliance_classes

   This is usually achieved at least in part by having at least two layers of insulating material between live parts and the user, or by using reinforced insulation. In Europe, a double insulated appliance must be labelled Class II or double insulated or bear the double insulation symbol: ⧈ (a square inside another square). As such, the ...

6. Bushing (electrical) - Wikipedia

   en.wikipedia.org/wiki/Bushing_(electrical)

   Insulated bushings can be installed either indoor, or outdoor, and the selection of insulation will be determined by the location of the installation and the electrical service duty on the bushing. For a bushing to work successfully over many years, the insulation must remain effective both in composition and design shape and will be key ...

7. Vacuum insulated panel - Wikipedia

   en.wikipedia.org/wiki/Vacuum_insulated_panel

   A vacuum insulated panel (VIP) is a form of thermal insulation consisting of a gas-tight enclosure surrounding a rigid core, from which the air has been evacuated. It is used in building construction, refrigeration units, and insulated shipping containers to provide better insulation performance than conventional insulation materials. [1] [2]
