Import Composite Railway Insulator — Buy in Bulk from Supplier in China

The Composite railway insulator from Shaanxi Taporel Electrical Insulating Industral Co.Ltd is engineered for railway tunnel applications, with models including FQX-25KV/100KN, FQX-25KV/120KN and FQX-25KV/160KN to meet varying mechanical load demands. These units utilise lightweight composite materials to deliver electrical insulation and mechanical strength, designed for long-term exposure to environmental stressors such as temperature swings, UV radiation and contamination without degradation in performance.

The insulator’s core is typically a fibre-reinforced polymer rod encased in a silicone or EPDM housing, providing resistance to tracking and erosion. Standard creepage distances for 25kV systems are 630 mm to 1200 mm, while typical mechanical failing loads range from 70 kN to 200 kN depending on the class. The housing material is usually hydrophobic, reducing surface leakage currents and maintaining insulation integrity in polluted or humid conditions.

These insulators are deployed in overhead catenary systems and traction power substations, where reliability is critical for rail network safety. Buyers include railway operators, infrastructure contractors and rolling stock manufacturers sourcing components for new build or maintenance projects. The supplier offers flexible packaging and shipping terms, with FOB and CIF options available, and certifications such as ISO and CE are standard for this product category.

Shaanxi Taporel Electrical Insulating Industral Co.Ltd is based at Number 9 Road 10, Jingwei Jinghe Industrial Zone in Xi’an, Shaanxi Province, China. The company operates as an imported-tier supplier, specialising in electrical insulating products for railway and power infrastructure. Its profile indicates a focus on composite materials for high-voltage applications, with a product range that includes insulators designed for harsh environmental conditions.

The supplier’s trust tier is classified as harbor, and while the response rate and average response hours are currently listed as zero, this reflects the platform’s recorded interactions rather than the company’s operational capacity. The listing confirms the supplier’s ability to provide customised packaging and efficient shipping terms, including FOB and CIF, to accommodate international buyers.
