Wire Insulation Types
One of the key components of a wire is its insulation. However, there is a number of factors that come into play. Things such as stability and long life, dielectric properties, resistance to high temperature, resistance to moisture, mechanical strength, and flexibility. There are also so many different wire insulation types.
Furthermore, there is no single insulation that is ideal in every one of these areas. However, there are many key Types of Wire Insulation. Polyvinyl Chloride, Fluorinated Ethylene-Propylene, Polyethylene, Nylon, also Thermoplastic Rubber. Furthermore, each of these is a major insulator for wire containing electricity.
Key Types of Wire Insulation
Polyvinyl chloride (PVC):
Found in all of the major types of wire and cable.
- Low voltage building wire insulation and jacketing
- Low and medium voltage equipment cable jacketing
- Also, control cable jacketing
- Indoor telecommunications cable
- Automotive wire
- Finally, flexible Cords
It is a flame and abrasion resistant material. Which is specially compounded for general-purpose applications. Therefore, resisting flames, oil, ozone, sunlight, and most solvents.
Fluorinated ethylene-propylene (FEP):
This is a melt-processible copolymer made of tetrafluoroethylene and hexafluoropropylene. Also, FEP has dielectric properties in addition to chemical inertness, heat resistance, weather resistance, as well as being tough and flexible.
Is lightweight, water-resistant, and chemically inert
Different types of polyethylene:
- Low-density (LDPE)
- Linear low-density (LLDPE)
- Medium-density (MDPE)
- High-density (HDPE)
- Chlorinated polyethylene (CPE)
- Cross-linkable polyethylene (XLPE).
Polyethylene’s low dielectric constant allows for low capacitance and low electrical loss. Therefore, making it an ideal choice for audio, radio frequency, and high voltage applications.
Is a very flexible wire insulation. Also, it is usually extruded over softer insulation compounds.
Several Key Components:
- Strong abrasion
- Additionally, chemical resistance
Properties of Thermoplastic Rubber:
- Higher processing speeds
- Wider usable temperature range
- In addition to, excellent heat, weather, and age resistance without curing.
