PVC insulation shielded wire

1.Application Of PVC insulation shielded wire

PVC insulation shielded wire finds application in a wide range of electrical and electronic systems where protection against electrical hazards and electromagnetic interference (EMI) is required. Some common applications include:

Power Distribution:

It is used for power distribution in residential, commercial, and industrial settings. It is commonly used for wiring electrical panels, distribution boards, and circuit breakers, where protection against short circuits, overloads, and electrical shocks is critical.

Control Circuits:

This wire is used in control circuits of various electrical systems, such as motor controls, industrial automation, and process control. The shielding layer helps to prevent interference from EMI/RFI, ensuring reliable operation of control signals and reducing the risk of equipment malfunction.

Communication Systems:

PVC insulation shielded wire is used in communication systems, including data networks, telecommunication networks, and audio/video transmission. The shielding layer helps to protect against EMI/RFI, ensuring clear and reliable signal transmission, especially in environments with high electromagnetic noise.

Audio/Video Cables:

It is commonly used in audio and video cables, such as HDMI cables, VGA cables, and audio cables. The shielding layer helps to minimize interference, ensuring high-quality audio and video signals with minimal distortion or artifacts.

Electronic Equipment:

Used in various types of electronic equipment, including appliances, computers, and electronic devices. It provides electrical insulation to prevent short circuits and electrical hazards, and the shielding layer helps to protect against EMI/RFI, ensuring reliable operation of electronic components.

Industrial Applications:

PVC insulation shielded wire is used in various industrial applications, such as manufacturing, process control, and equipment wiring. It provides protection against electrical hazards and interference from EMI/RFI, ensuring safe and reliable operation of industrial systems.

2.Construction Of PVC insulation shielded wire

The construction of PVC (Polyvinyl Chloride) insulation shielded wire typically involves several layers that provide electrical insulation, shielding, and protection.

Conductor:

The conductor is the core of the wire and is usually made of copper or aluminum. It carries the electrical current.

Insulation:

The conductor is coated with a layer of PVC insulation, which is a type of thermoplastic material that provides electrical insulation. PVC is known for its excellent electrical properties, durability, and resistance to moisture, chemicals, and UV radiation.

Shielding:

Over the PVC insulation, a layer of shielding is applied to protect against electromagnetic interference (EMI) and radio frequency interference (RFI). The shielding layer is typically made of metal, such as aluminum or copper, in the form of foil or braided wires. The shielding layer helps to minimize signal distortion and maintain signal integrity.

Insulation Shield:

A layer of insulation shield is applied over the shielding layer. The insulation shield is typically made of PVC material and serves as a barrier between the shielding layer and the outer jacket.

Jacket:

The entire construction is then covered with an outer layer called the jacket, which is made of PVC or other suitable materials. The jacket provides mechanical protection to the wire, preventing it from damage due to abrasion, moisture, and environmental factors.

Additional Layers:

Depending on the specific application and requirements, additional layers such as fillers, binders, or strength members may be added to enhance the mechanical or electrical properties of the wire.
