Products Description
Electrical Grade Insulation Crepe is a type of insulating paper, which is reprocessed from cable paper made of sulfate pulp. It has very good electrical properties in oil, showing a high average breakdown voltage and a small tangent value of the dielectric loss angle. Crepe paper is mainly used for wrapping the outgoing wires of transformers. Our company produces and provides electrical-grade insulation crepe paper, which complies with IEC 60554-3-5 standards and is widely used for power distribution and power transformer lead wire and coil insulation.

transformer tips
Mechanical strength of paper insulation materials.
In addition to the fiber composition, density, permeability and uniformity of the paper, the most important factors in selecting paper insulation materials for oil-immersed transformers also include mechanical strength requirements, including tensile strength, punching strength, tear strength and toughness:
① Tensile strength: When the paper fiber is subjected to a tensile load, it is required to have the maximum stress that it can withstand without being broken.
② Punching strength: A measure of the ability of paper fibers to withstand pressure without being broken.
③ Tear strength: The force required to tear paper fibers is required to meet the corresponding standards.
④ Toughness: The strength of paper when folded or cardboard is bent can meet the corresponding requirements.
