Description

Waterproof electric wire

Technical Field

Background

The electric wire is necessary equipment for electric power transportation, and the function of the electric wire is to transmit electric power. The electric wire is divided into a bare wire, an electromagnetic wire and an insulated wire.

The bare wires have no insulating layer and comprise copper, aluminum flat wires, overhead stranded wires and various profiles (such as molded lines, buses, copper bars, aluminum bars and the like). It is mainly used for outdoor overhead and indoor bus bars and switch boxes.

Magnet wires are insulated wires that, when energized, produce a magnetic field or induce a current in a magnetic field. It is mainly used for motor and transformer coils and other relevant electromagnetic equipment. The conductor is mainly a copper wire, and has a thin insulating layer, good electrical and mechanical properties, heat resistance, moisture resistance, solvent resistance and the like. Different insulating materials are selected to achieve different characteristics. The electromagnetic wire mainly comprises an enameled wire and a lapped wire. The enameled wire is made by coating insulating paint on a bare copper wire, has a thin insulating layer and small occupied volume, and is widely applied to various electric machines, electric appliances, instruments and meters. The properties of the enamel wire vary depending on the nature of the insulating material used. The lapped wires mainly comprise yarn covered wires, silk covered wires, glass silk covered wires, paper covered wires, plastic film covered wires and the like, wherein the yarn covered wires and the silk covered wires are possibly eliminated due to poor temperature resistance, large occupied volume and the like. The glass fiber covered wire is formed by wrapping glass fibers outside a round copper wire and impregnating the round copper wire with organic silicon resin, can resist high temperature of 180 ℃, and has good insulating property and mechanical strength. The paper-covered wire is mainly used for oil-immersed transformers. The plastic film covered wire is made by coating polyimide film with some adhesive and baking and fusing the polyimide film on the conductor. The insulating layer is tough and elastic, is easy to wind, is wear-resistant and heat-resistant, and is widely applied to equipment for space navigation and the like.

Insulated wires are generally composed of a conductive wire core, an insulating layer, and a protective layer. The wire core can be divided into a hard type, a soft type, a movable type and an ultra-soft type according to the use requirement. The wire cores are four types, namely a single core, a two-core, a three-core and a four-core. The insulating layer is generally made of rubber, plastic or the like. Such insulated wires are widely used for various instruments and meters, telecommunication equipment, power lines and lighting lines having an ac voltage of 500 v or less and a dc voltage of 1000 v or less.

Outdoor electric wires are often exposed outdoors, and the electric wires are required to have good waterproof shape and toughness, so that the electric wires are prevented from being immersed in water and damaged to cause safety accidents.
