Import 360 Epoxy Resin Fiber Glass Winding Tube — Buy in wholesale FOB from Supplier in China

The 360 Epoxy Resin Fiber Glass Winding Tube from Ztelec Group is a filament-wound composite insulator produced by impregnating fiberglass yarn with epoxy resin, then winding in a wet process before drying and consolidation. The resulting tube exhibits low dielectric loss, excellent electrical insulation, and mechanical rigidity under thermal stress, rated for continuous operation at heat resistance classes F (155 degrees C) and H (180 degrees C). Ztelec Group manufactures this product at its facility in Zhengzhou, Henan province, China.

The tube's epoxy matrix provides chemical resistance against transformer oils, SF6, and common industrial contaminants, while the glass fiber reinforcement prevents deformation under radial and axial loads. Typical wall thicknesses and diameters follow industry standards for transformer bushings and switchgear bushings, though exact dimensions should be confirmed with the supplier for each order. The winding construction ensures uniform resin distribution and void-free insulation, critical for partial discharge performance in high-voltage applications.

Primary buyers include manufacturers of dry-type transformers, on-load tap changers, line reactors, surge arresters, and SF6-filled inductors. The product serves as a structural insulator and coolant channel in these devices. Trade terms, minimum order quantities, and lead times are not stated in the listing data and should be requested directly from Ztelec Group. Custom lengths and bore diameters are typically available from epoxy tube specialists upon engineering review.

Ztelec Group is headquartered in Zhengzhou, Henan province, China, with its address at No.279 Third West Ring Road in the 450000 postal zone. The company operates within the harbor trust tier on the platform, with a response rate of 0.00 percent and no recorded average response hours, indicating limited or no recent buyer engagement through the platform messaging system. Buyers should expect delays in initial contact and plan to follow up directly via the supplier's listed contact channels.

The supplier's profile focuses on electrical insulation materials, specifically epoxy resin fiber glass winding tubes for power equipment applications. No verified factory size, annual revenue, employee count, or specific certifications are disclosed in the source data. The product description emphasizes heat resistance classes F and H, wet winding manufacture, and chemical resistance, positioning Ztelec Group as a specialist in transformer-grade insulation rather than a general composites manufacturer. Buyers should verify the supplier's quality management system, sample testing protocols, and any IEC or UL certifications before committing to volume orders.
