China Cable Kraft Paper Insulation for Oily Cables - High-Temperature Suppliers & Factory Solutions
Product Description
Kraft paper for cables is a widely used packaging and insulation material in cable manufacturing, with unique physical and chemical properties. The following is a detailed introduction to kraft paper used for cables:
1. Material Composition
The kraft paper used for cables is mainly made of natural fibers, such as kraft paper pulp. These fibers are processed through processes such as pulping and papermaking to form soft and resilient paper.
2. Main Characteristics
Physical properties: Kraft paper has high tensile strength and elongation at break, and can withstand certain loads and impacts. At the same time, its light weight makes it easy to use in cable manufacturing.
Insulation performance: Kraft paper has good insulation performance, which can effectively isolate cables from contact with the external environment, prevent current leakage and short circuits.
Heat and voltage resistance: Kraft paper used for cables can withstand high temperatures and high voltages, and can maintain stable performance in harsh working environments.
Waterproof and moisture-proof: Kraft paper also has certain waterproof and moisture-proof properties, which can protect cables from the influence of humid environments.
3. Main Functions
Isolation and Insulation: Kraft paper for cables is mainly used to isolate conductors from insulation layers, prevent arcing between conductors and insulation layers, and improve the electrical and safety performance of cables.
Protecting cables: During the cable manufacturing and packaging process, kraft paper provides necessary physical protection for cables to prevent them from being corroded and damaged by the external environment.
4. Application Fields
Kraft paper for cables is widely used in the manufacturing and packaging fields of cables. In the cable production process, kraft paper is used as a wrapping material to wrap between the cable conductor and insulation layer, playing a role in isolation and insulation. At the same time, kraft paper is also used as an outer packaging material in the packaging and transportation of cables to protect them from mechanical damage and the influence of humid environments.
5. Precautions
When using kraft paper for cables, attention should be paid to the selection of its specifications and sizes to ensure that it can meet the needs of cable manufacturing and packaging. At the same time, attention should be paid to the storage and preservation conditions of kraft paper to avoid moisture, heat, or other physical damage.
