Cable (wire) grade is a letter designation (sometimes using numbers) characterizing the material of the conductive cores, insulation, degree of flexibility and design of protective covers. Each manufacturing plant indicates this special code on its products.
For better orientation in our products, we offer a short guide to cable and wire markings. The reference book offers a decoding of alphanumeric abbreviations for cables and wires.
Wires are products with conductors in insulation and winding, designed to connect a source of electric current to a consumer.
Wires and cables are available with insulation for voltages of 380, 660 and 3000 V AC, used for any possible voltage. The conductor of the insulated cable is protected by a sheath made of polyvinyl chloride (PVC), rubber or vinyl plastic. Wires and cables of some brands have a special braid on the outside of the insulation that protects against mechanical damage.
An electrical cord is a flexible insulated wire (cross-section from 0.35 to 1.5 mm2), which is used to connect household electrical appliances and radio equipment to the electrical network.
A cable is a wire with an insulating winding, located in one or more protective sheaths. The cable may contain armor (steel or wire), screen, core, filler, metal sheath, outer sheath. Each element is necessary for the cable to operate under certain environmental conditions in which it is located.
Non-flammable cable (marked LS) is often called fire-resistant cable. But flame retardant cable (cable that does not support combustion) is a group of cables designed to resist the spread of fire to a new area. Flame resistant cable, unlike non-flammable cables, is designed to maintain circuit integrity and must continue to operate for a specified period of time under certain conditions, particularly fire and open flame conditions. Without any doubt, both types of cable, non-flammable and fire-resistant, play an important role in maintaining the integrity of the environment and industrial environment during a fire and increasing the chances of human rescue and survival. It can be said that a fire-resistant cable is a more advanced version of a non-flammable cable, but not vice versa.
