This allows electrons to gain energy and thereby move through a conductor such as a metal if no such states are available the material is an insulator. These markings provide important information about the wiring and insulation including the wire size and material the type of insulation the number of wires contained inside a cable and any special ratings or characteristics of the wire.

Cable insulation materials the following materials are typically used for cable insulation. Rancho dominguez 2050 e. Understanding electrical wiring labeling. Vista bella way rancho dominguez ca 90220 310 609 1811 800 326 0006 fax.

Conductors are of different materials. Thermoset insulation with oil resistant thermoset cover. Electrical insulation is the absence of electrical conduction electronic band theory a branch of physics dictates that a charge flows if states are available into which electrons can be excited. Pvc polyvinyl chloride is the most commonly used thermoplastic insulator for cables.

Among the most common are type w and type g. Alan loibl created date. Conductors are the only power carrying path in a power cable. Types of screening twisted pair tp screening conductor types.

Solid class 2 stranded class 5 flexible class 6 extra flexible mostly used for cords and welding etc. Thermoplastic thermoplastic compounds are materials that go soft when heated and harden when cooled. Abbreviation code cable type code power and control cable insulation and or sheath materials insulation inner or outer sheath of polyvinylchloride pvc y insulation made of cross linked polyethylene xlpe 2x. It is cheap durable and widely available.

Complete catalog printed updated 11 06 pdf author. Rated for stage and garage use. Crossed linked synthetic polymer very tough moisture and heat resistant. Replaced welding cable as in acceptable stage cable until type sc was developed.

Both cables are a heavy duty construction can withstand frequent flexing and carry a voltage rating of up to 2 kv. The outer sheath of cables consists of extruded polyvinyl chloride pvc or zero halogen material lszh. Electrical wires and cable have markings stamped or printed on their insulation or outer sheathing. Various degrees of screening are used according to the cable type and application.

Within a metal control cabinet to foil or braid shielded cable for areas of high emi or electrical interference. The colour is primarily black. Same as x wire but solid or seven stranded 302 f.
