PVC Cable Material of Power grid cable

PVC (Polyvinyl Chloride) is a common material used for insulation and sheathing in power cables, including those used in power grid applications.

PVC compounds for wire and cable are made from polyvinyl chloride resin, with the addition of plasticizers, stabilizers, flame retardants, pigments. These ingredients are mixed, plastified, and granulated to produce a granular material. This material is ideal for producing plastic-insulated, flameardant cables. Our product is made using advanced production technology, offering excellent extrusion processing performance and outstanding Flame Retardancy. The product has a wide range of parameters, making it suitable for various types of extruders and very easy to operate.

1. Reference Extrusion Equipment: (1) Recommended screw L/D ratio of 20:1 to 30:1. (2) is suggested to add two layers of 60-mesh filters based on the equipment's plastication capability and the appearance of the extruded material.

Here's some information about PVC as a cable material:

1. **Durability**: PVC is known for its durability and resistance to moisture, abrasion, and many chemicals. This makes it suitable for outdoor and underground applications.

2. **Flexibility**: Depending on the formulation, PVC can be made flexible or rigid. Flexible PVC is often used in cables that require bending, while rigid PVC is more commonly used in structural applications.

3. **Temperature Range**: PVC cables generally operate within a temperature range of -15°C to 60°C. However, special grades of PVC can withstand higher temperatures up to around 90°C.

4. **Flame Retardancy**: PVC has inherent flame-retardant properties, which is crucial for safety in electrical installations.

5. **Standards and Regulations**: The use of PVC in cables must comply with various international and national standards, such as IEC (International Electrotechnical Commission), IEEE (Institute of Electrical and Electronics Engineers), and local regulations regarding safety and performance.

6. **Applications in Power Grids**: In power grid applications, PVC cables are used for both distribution and transmission purposes, depending on the specific requirements of the system and the environment in which they will be installed.

When specifying PVC cables for power grid applications, it's important to consider the specific environmental conditions, operational requirements, and compliance with relevant standards.
