China Cable Crepe Paper Insulation - High-Quality Suppliers & Factory for Superior Electrical Protection
Product Description
Crepe paper for cables plays an important role in cable manufacturing, mainly used for insulation and wrapping of cables. The following is a brief introduction to corrugated paper for cables:
Crepe paper for cables is usually made of insulating materials such as unbleached kraft paper pulp. These materials undergo specific processes such as pulping, wrinkling, etc. to form paper with a wrinkled surface.
Electrical performance: Crepe paper used for cables has good electrical insulation properties, which can effectively isolate the conductors inside the cable from the external environment, prevent current leakage and short circuits.
Physical properties: Crepe paper has high physical strength, including tensile strength, flexural strength, and tear strength, and can withstand various mechanical stresses during the manufacturing, transportation, and use of cables.
Heat and pressure resistance: Crepe paper used for cables usually has good heat and pressure resistance, and can maintain stable performance in high temperature and high voltage environments, ensuring the safe operation of cables.
Chemical stability: Crepe paper can withstand oil, humidity, and other chemicals that may exist inside the cable, maintaining its insulation performance unaffected.
Insulation protection: Crepe paper for cables is mainly used for the insulation layer of cables, isolating conductors from the external environment, preventing current leakage and short circuits, and improving the electrical and safety performance of cables.
Enhance electric field distribution: In ultra-high voltage oil filled cables, semiconducting corrugated paper can evenly distribute the electric field, reduce the uneven distribution of the electric field, and improve the voltage resistance of the cable.
Increasing surface area: In high-voltage cables, insulation corrugated paper is also used to divide the various strands of the conductor, increase the surface area of the conductor, and reduce the AC resistance of the conductor.
Crepe paper for cables is widely used in the manufacturing of various types of cables, including high-voltage cables, ultra-high voltage oil filled cables, etc. Crepe paper can be seen in the insulation layer, filling layer, shielding layer and other parts of the cable.
When using corrugated 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. At the same time, attention should be paid to the storage and preservation conditions.
