Import Flexible Crepe Paper Tubes — Buy in Bulk from Supplier in China

Flexible crepe paper tubes from Wei He Electric Co., Ltd. are engineered for electrical insulation in high-voltage environments, constructed from electrical-grade crepe paper with a density of 120 to 150 gsm. The tubes exhibit a tensile strength of 15 to 25 N/mm² and can withstand continuous operating temperatures up to 130°C, as confirmed by the supplier’s material data sheet. Their flexibility allows for easy wrapping around conductors without cracking or delamination during installation.

The base material is untreated kraft crepe paper, processed to enhance dielectric properties without chemical coatings. Typical industry standards for such tubes include IEC 60851-5 for electrical insulation and ASTM D150 for dielectric loss measurements. These tubes are not laminated or resin-impregnated, preserving their breathability and thermal dissipation characteristics. The wall thickness ranges from 0.25 mm to 0.5 mm, with standard inner diameters of 3 mm, 5 mm, and 8 mm, suitable for wire gauges up to 16 AWG.

These tubes are primarily used in transformer winding insulation, capacitor lead separation, and motor stator slot liners within the industrial and automotive sectors. Buyers include cable manufacturers, transformer assemblers, and OEMs in China and Southeast Asia. Packaging is in bulk rolls of 100 meters, sealed in moisture-resistant polyethylene, with standard export cartons. Trade terms are typically FOB Shanghai, with MOQs negotiable based on size and volume.

Wei He Electric Co., Ltd. is a manufacturer based in Suzhou, Jiangsu, with a registered address at South Of Dongwu No173. The supplier is classified as imported and verified through harbor trust signals, indicating active export compliance. The listing confirms no revenue, workforce, or certification data, and no client references are provided. The company’s focus appears limited to the production and export of electrical insulation components, with no indication of upstream material sourcing or R&D activity.

There is no public record of certifications, years in operation, or factory audits referenced in the listing. The supplier’s response rate and average reply time are recorded as zero, suggesting limited buyer communication capacity. Buyers should treat this as a direct manufacturer with no branding or marketing infrastructure visible. Product quality relies on material consistency and process control, not third-party validation.
