Welding cable usually comes with rubber insulation, typically either Neoprene or Ethylene Propylene Diene Monomer (EPDM) rubber, and is designed to be fire (small sparks), water, oil, and abrasion resistant.

Welding cable is made from stranded bundles of copper wire tightly packed and insulated. The wire stranding gives the cable more flexibility and resistance to wear, while the insulation (typically EPDM or Neoprene rubber) adds additional protection against the harsh environments found in welding applications and is more flexible than PVC or other rubber coatings.

Ampacity is short for ampere capacity. For welding cables, ampacity refers to the maximum amount of electrical current a spool of cable can conduct before advanced deterioration sets in. For more detail on ampacity.

Portable cable, also called portable cord, is designed for temporary power supply applications, rather than for permanent installations. This cable is often referred to as “service cord” when supplying electricity to motors or appliances. Other, non-portable power supply cables may be installed permanently in buildings as overhead wiring, exposed wiring, or in direct burial applications to provide long-term electrical service.

The nominal cross-sectional area are 0.5mm2, 0.75, 1, 1.5, 2.5, 4, 6, 10, 16, 25, 50, 70, 95, 120, 150, 185, 240, 300, 400, 500, 630, 800, 1000, 1200, 1600, 2500, 3000mm2, the AWG are 24 to 0AWG and 1 to 4/0 AWG, and 250 to 3000MCM.

The common insulation material of power cable are PVC, XLPE, PE, Rubber, Fluoroplastic, and some special mineral compound.

The usual armor material of power cable are Steel wire (SWA), steel tape (STA), aluminum wire (AWA), aluminum tape (ATA), and others special material as steel wire braided (SWB).

The usual shield material of power cable are copper wire (CWS), copper tape (CTS), aluminum foil, and others composited material as aluminum-plastic composited tape.

Welding cable is made to be extremely durable and flexible. Arc-welding requires a person to move the electrode around the shop and along the joints being welded, so it is essential to have a flexible welding cable that allows for ease of movement. A high strand count, concentrically arranged, and rubber insulation help increase the cable's flexibility.

Aerial bundled cables (also aerial bundled conductors or simply ABC) are overhead power lines using several insulated phase conductors bundled tightly together, usually with a bare neutral conductor.
