Product Detail

Product Description

Power cable PE filling strip is a commonly used non-hygroscopic filling material in the cable production process. They are mainly used to fill the gaps between the cores during cable formation to ensure the stability of the cable structure and the roundness of the shape.

1. Basic Characteristics

Material Composition:

PE filling strips for power cables are mainly made of high molecular weight materials such as polyolefins, and added with appropriate amounts of plasticizers and flame retardants (optional according to demand), which are foamed, plasticized, and extruded. Some products will also be processed into filling strips made of other materials such as polyvinyl chloride (PVC) according to customer needs.

Physical Performance:

Good molding and stability, high mechanical strength, can fully ensure the structural stability of the cable during formation.
Low density helps to reduce the manufacturing cost and overall weight of cables.
The oxygen index of flame-retardant filling strips is high, which can effectively improve the flame retardant performance of cables (for filling strips with added flame retardants).

Specifications and Dimensions:

The specifications and sizes of filling strips vary depending on the manufacturer and product usage, and there are generally multiple specifications to choose from. Common specifications include 3*25, 3*35, 3*50, etc., with specific dimensions including height, width, arc radius, and other parameters.

2. Application Advantages

Improve Cable Roundness:

The filling strip is relatively hard and has good compressive deformation resistance. It can firmly fill the edge gaps of the cable, ensure the roundness of the cable after it is formed, and improve the appearance quality of the cable.

Support and Protection:

For cables with irregular twisted structures (such as 4-core, 5-core, 6-core, etc.), the filling strip can effectively support the insulated wire core, avoiding being flattened during cable bending or traction, resulting in the cable core not being round or the outer diameter exceeding the range.

Reduce Costs:

Compared with filling ropes, filling strips are used less when filling the same gaps, which helps to reduce the manufacturing cost of cables.

3. Usage and Storage

Precautions for Use:

In the process of cable formation, the appropriate size and quantity of filling strips should be selected according to the specific specifications and structure of the cable. Ensure that the filling strip is placed correctly to fully utilize its supporting and protective functions.

Storage Requirements:

The filling strip should be stored in a clean, cool, dry, and ventilated warehouse, avoiding direct sunlight and humid environments. Regularly check the inventory status of filling strips and replenish them in a timely manner to ensure production demand.

4. Market and Development

With the continuous development of the power industry, the requirements for cable performance are also increasing. As one of the important materials in the cable production process, PE filling strips are used for power cables, and their market demand is constantly increasing. Meanwhile, with the continuous advancement of materials science and processing technology, the performance and quality of filling strips will also be further improved and optimized.

Frequently Asked Questions (FAQ)

What is the primary purpose of a power cable PE filling strip?

Power cable PE filling strips are non-hygroscopic materials used to fill the gaps between core conductors during cable formation. This ensures the structural stability of the cable and maintains its round shape.

What materials are used to manufacture these filling strips?

They are mainly made from high molecular weight polyolefins, with plasticizers and flame retardants added as needed through foaming, plasticizing, and extrusion. Custom options like Polyvinyl Chloride (PVC) are also available.

How do PE filling strips help lower manufacturing costs?

PE filling strips have a low density which reduces the overall weight of the cable. Additionally, they fill equivalent gaps using less material compared to traditional filling ropes, helping to lower production expenses.

Can PE filling strips prevent cables from flattening during installation?

Yes. Because the filling strips are relatively hard and have excellent compressive deformation resistance, they support the insulated wire core and prevent flattening when the cable is bent or pulled.

What are the recommended storage conditions for PE filling strips?

They should be stored in a clean, cool, dry, and well-ventilated warehouse. It is crucial to avoid direct sunlight and damp environments to preserve their material properties.
