The 3641 epoxy-resin fiberglass laminated tube is engineered for electrical insulation applications, constructed from epoxy resin, a curing agent and alkali-free glass cloth. It meets the GB/T 5132.1-2009 and IEC61212-1:2006 standards, with heat resistance classified as B, F or H depending on the raw material composition used in production.
This tube offers superior dielectric properties and machinability, making it suitable for precision fabrication into components like dry-type transformer coil insulation tubes and transformer end insulation. Alkali-free glass cloth reinforcement provides dimensional stability and mechanical strength, while the epoxy matrix ensures resistance to moisture and chemicals typical in electrical environments.
Common buyers are manufacturers of transformers, switchgear and electrical motors sourcing structural insulation parts. The material is supplied in bulk lengths and can be cut to specification, with typical diameters ranging from 10 mm to 200 mm and wall thicknesses from 1 mm to 10 mm. Confirm exact dimensions and tolerances with the supplier, as these vary by application and production batch.

Ztelec Group operates from Zhengzhou in Henan Province, China, with a registered address at No. 279 Third West Ring. The company specialises in electrical insulation materials, including laminated tubes and structural components for transformers and switchgear. Its profile indicates a focus on industrial B2B supply chains, though public verification signals such as response rate and average response time are currently unreported.
The supplier’s listed trust tier is classified as harbor, which reflects a baseline level of commercial activity but without additional performance metrics. No employee count, production capacity or client references are provided in the available data. Buyers should verify manufacturing capabilities and certifications directly, as the profile does not confirm ISO or other quality system adherence.

Before placing an order, confirm the heat resistance class (B, F or H) and the exact dielectric properties required for your application. Request third-party test reports for dielectric strength, volume resistivity and mechanical properties to ensure the material meets your technical specifications. Verify whether the supplier can provide custom lengths or diameters outside the typical range.
Discuss logistics details such as packaging, Incoterms and lead times. These tubes are typically shipped in wooden crates or cartons to prevent damage, with standard lot sizes varying by diameter and length. Clarify whether the supplier can accommodate FOB Zhengzhou or CIF to your port, and agree on payment terms such as TT or LC. Lead times may range from 4 to 8 weeks depending on order volume.
Quality control should include visual inspection for surface defects, dimensional checks against your drawings and electrical tests if the components are critical. Request a pre-shipment inspection report and ensure the material is accompanied by a certificate of compliance with GB/T 5132.1-2009 or IEC61212-1:2006. For high-voltage applications, consider independent lab testing for dielectric breakdown strength.
