A fish tape (also called a draw wire, draw tape, or an electrician ' s snake) is a tool used by electricians to route new wiring through walls and electrical conduit. [1] Made of a narrow band of spring steel, by careful manipulation, the tape can be guided through confined spaces such as wall cavities or conduits in many countries. The goal is ...
An electrical conduit is a tube used to protect and route electrical wiring in a building or structure. Electrical conduit may be made of metal, plastic, fiber, or fired clay. Most conduit is rigid, but flexible conduit is used for some purposes. Conduit is generally installed by electricians at the site of installation of electrical equipment.
Electrical tape (or insulating tape) is a type of pressure-sensitive tape used to insulate electrical wires and other materials that conduct electricity. It can be made of many plastics but PVC (polyvinyl chloride, "vinyl") is the most popular, as it stretches well and gives effective and long-lasting insulation.
Self-amalgamating tape is a non-tacky silicone rubber tape that when stretched and wrapped around cables, electrical joints, hoses, and pipes combines or unites itself into a strong, seamless, rubbery, waterproof, and electrically insulating layer. [1] [2] Unlike many other polymers and fibers, it is heat-, sunlight-, and weather-resistant.
Corrugated hoses are used as economical, flexible connecting elements that permit movement, thermal expansion and vibrations, and that can be used as filling hoses. The starting material is a seamless or longitudinally welded, thin-walled tube into which corrugations are introduced by mechanical or hydraulic means using special tools.
Electrical conduit risers, seen inside fire-resistance–rated shaft, as seen entering bottom of a firestop. The firestop is made of firestop mortar on top, rockwool on the bottom. Raceways are used to protect cables from damage. Insulated wires may be run in one of several forms between electrical devices.

The cables are bound together by a durable material such as rubber, vinyl, electrical tape, conduit, a weave of extruded string, or a combination thereof. [2] Commonly used in automobiles, as well as construction machinery, cable harnesses provide several advantages over loose wires and cables. For example, many aircraft, automobiles and ...
