Abstract
The invention discloses an electric wire, and belongs to the field of structural design of electric wires and cables. The electric wire comprises a conductor core stranded by a plurality of metal filaments, an internal insulating layer coated on the external surface of the conductor core, a fire-resistant coating coated on the external surface of the internal insulating layer, a mica tape coated on the external surface of the fire-resistant coating and an external insulating layer coated on the external surface of the mica tape. The electric wire overcomes the problems of low tensile strength, poor buckling resistance and no fire resistance of an electric wire in the prior art, so that the tensile strength, the buckling resistance and the fire resistance of the electric wire are improved, and a requirement for the electric wire in a new situation is met.
Description
technical field [0001] The invention relates to the field of structural design of electric wires and cables, in particular to an electric wire. Background technique [0002] Wire and cable refers to materials used for power, communication and related transmission purposes. Wires and cables don't have strict boundaries. Products with fewer cores, small product diameters, and simple structures are usually called wires, those without insulation are called bare wires, and others are called cables. [0003] The wire is composed of one or several soft wires, covered with a light and soft sheath. With the improvement of living standards, people have put forward higher performance requirements for the wires of electrical equipment, requiring high tensile strength, good bending resistance, durability, and certain fire resistance. However, electric wires in the prior art have no way to meet the above-mentioned requirements. Contents of the invention [0004] Aiming at the above-...
