Why wires are insulated

One reason to use insulated wire is to prevent electrical shock. If a wire is exposed, people and animals who come into contact with it can be shocked. Exposure can also predispose wiring to shorts and other issues. Water splashing onto the wire, for instance, can act as a conductor and create an electrical fire or another problem.

Insulation also reduces leakage and increases operating efficiency, as well as protects the wire from corrosion. Manufacturers of insulated wire may color code their products. The colors can provide information about the situations the wire is rated for, and can also be useful for complex wiring applications where technicians want to be able to trace different wires.

Color codes can be followed to link wires to the correct connectors, which can be useful in installation as well as maintenance activities. It has superior mechanical strength, and its very low dissipation factor makes it an electrically efficient option.

PFA is an expensive material. Polytetrafluoroethylene PTFE is an extremely flexible, and water, oil, chemical, and heat resistant thermoplastic material.

When foamed, it improves data transmission, which also improves pricing and processing. It is commonly used in plenum cable and military applications.

Foaming the material reduces weight and improves data transmission. However, the materials lack the electrical advantages offered by FEP.

Polyvinylidene Fluoride PVDF aka Kynar is a flexible, lightweight and thermally stable insulation material with chemical, heat, weather, abrasion, and fire resistant properties. Its relatively low-cost makes it an insulation option for a wide range of industries and applications. Its UL standard Plenum Cable Flame Test rating deem it suitable for application in a building space requiring air circulation necessary for dropped ceilings or raised floors. Email Us or Call Search.
