How to Insulate Copper Wire

Insulating your electrical copper wiring will protect your wire from the elements, and, most importantly, will protect the wiring from catching fire. Most electrical wire y is insulated, but you should avoid using uninsulated wiring because there is a risk of fire and electrical shorts. Insulate your wire as a last resort. You should try to replace it with insulated wire, preferably nonmetallic sheathed cables.

Instructions

1, Install PVC conduit at the location where you want to use your uninsulated wire and glue with fittings and PVC solvent cement. Use the brush that comes with the PVC solvent cement to spread a thin layer and hold the conduits together for 30 seconds until the solvent dries. You must run a separate PVC conduit for each cable if they are uninsulated.

2, Connect conduits to a plastic electrical box. Push the conduit into the hole of the electrical box and secure in place with electrical conduit box connector by snapping the connector on. Do not use a metal box if your cable is uninsulated.

3, Wrap end of cable on wire puller, so it forms a knot at the tip of the wire puller. Wrap the tip of the wire puller with electrical tape to secure the wire to the wire puller. Leave the cable unrolled so you can push it easier through the conduits.

4. Pull cable through electrical conduit with the wire puller. Use wire lubricant if it gets stuck. Squirt the entrance of the electrical conduit until its covered with lubricant and the tip of the wire puller with wire lubricant to ease it through the conduit.

5. Connect cable to intended receptacle in the plastic electrical box.

6. Wrap all exposed wires in the electrical box with electrical tape. This will prevent the wires from touching and shorting.

enameled aluminum wire manufactuerer

Enamelled aluminum wire is one of the main varieties of the winding wire which is composed of a conductor and an insulating layer. Bare wire soften after annealing, and then several pain, finally bake. But it is difficult to produce that meet the standard requirements, but also to meet customer requirements. It is subject to raw material quality, process parameters, production equipment, environment and other factors. Therefore, the quality characteristics of enameled aluminum wire and enamelled copper wire does not the same. but are equipped with mechanical properties, chemical properties, electrical properties, thermal properties of the four properties.

Enamelled aluminum wire has high heat resistance, excellent mechanical properties, electrical properties and chemical properties and excellent resistance to freezing performance. It can apply for refrigeration equipment under 200 ℃ long-term work conditions and electrical equipment, dry-type transformers, oil-immersed transformers and epoxy cast transformers by chemical erosion. And enameled aluminum wire also can used in separators, electromagnets and other electrical equipment.

Zhengzhou LP Industry Co., Ltd is a professional manufactuerer of enameled aluminum wire. This company have been devoted to supplying enameled aluminum wire from 1993. 

enameled round copper wire

Enameled round copper wire is an important kind of magnet wire. Compared to an ordinary polyester enameled wire, enameled round copper wire has high resistance to abrasion, and is more superior in dielectric properties and solvent resistance. At the same time , it has high heat resistance, good thermal shock, better cut through and better performance properties. What is enameled round copper wire’s application with such high-quality mechanical properties.

Generally speaking, enameled round copper wire has no pinhole resistance, solderability, high breakdown voltage, high-frequency resistance and dielectric loss and other small features. And 200 polyester-imide enameled round copper wire is a replacement product. The product has a small friction coefficient and strong resistance to degradation of performance, and no pinholes and other characteristics and for high-speed automated routing winding.

kapton magnet wire

Kapton magnet wire is premium copper or aluminum conductor, evenly wrapped with polyimide film or polyimide, fluorine 4.6 composite film. Fluorine 4.6 can be melt and make a whole with the film and conductor after heated.

Kapton magnet wire has strong voltage resistance, thin thickness and thermal class up to 220℃. The product is widely applied in electric machines、reactors、electric welding machines and similar electrical instruments. The electrical bare copper or aluminum wire with extrusion process is the ideal material for polyimide film wrapped copper or aluminum wire.
