2. Chicken wire - Wikipedia

   en.wikipedia.org/wiki/Chicken_wire

   The lines have a pattern similar to that of chicken wire. In machine tool design, chicken wire may be used for safety guarding. Chicken wire is sometimes used to provide grip on surfaces such as wooden steps or decking. Chicken wire commonly used in construction has been found to block or attenuate Wi-Fi, cellular and other radio frequency ...

3. Passive fire protection - Wikipedia

   en.wikipedia.org/wiki/Passive_fire_protection

   Fire-resistance rated wall assembly with fire door, cable tray penetration and intumescent cable coating. Passive fire protection (PFP) is components or systems of a building or structure that slows or impedes the spread of the effects of fire or smoke without system activation, and usually without movement.

4. Electrical conduit - Wikipedia

   en.wikipedia.org/wiki/Electrical_conduit

   Galvanized rigid conduit (GRC) is galvanized steel tubing, with a tubing wall that is thick enough to allow it to be threaded. Its common applications are in commercial and industrial construction. [1] It is designed to protect wire and connectors. Intermediate metal conduit (IMC) is a steel tubing heavier than EMT but lighter than RMC. It may ...

5. Mineral-insulated copper-clad cable - Wikipedia

   en.wikipedia.org/wiki/Mineral-insulated_copper...

   The cable meets and exceeds BS 5839-1, making it fire-rated surpassing 950°c for over three hours with simultaneous mechanical stress and water spray as well without failure. MI cable is primarily used for high-temperature environments or safety-critical signal and power systems; however, it can additionally be used within a tenanted area ...

6. Fire-resistance rating - Wikipedia

   en.wikipedia.org/wiki/Fire-resistance_rating

   A fire-resistance rating typically means the duration for which a passive fire protection system can withstand a standard fire resistance test. This can be quantified simply as a measure of time, or it may entail other criteria, involving evidence of functionality or fitness for purpose.

7. Electrical wiring - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring

   A somewhat similar system called "concentric wiring" was introduced in the United States around 1905. In this system, an insulated electrical wire was wrapped with copper tape which was then soldered, forming the grounded (return) conductor of the wiring system. The bare metal sheath, at earth potential, was considered safe to touch.

9. Plenum cable - Wikipedia

   en.wikipedia.org/wiki/Plenum_cable

   Plenum-rated and riser-rated cables are restricted to only allow certain chemicals for manufacture of the wire insulation and cable sheath. Typically this results in reduced flexibility of plastic cables, making it stiff and hard to bend. The bend radius may also be increased, and tight bends can potentially crack or tear the insulation and ...
