Key features

High Mechanical Strength: Rated mechanical tensile failure load up to 550KN with high tensile strength >1200Mpa.

Superior Anti-Fouling: Silicone rubber housing provides excellent hydrophobicity and pollution flashover prevention.

Compact & Lightweight: Small size and light weight, ideal for tunnels with limited clearance where porcelain fails.

Corrosion Resistant: Stainless steel or galvanized support arms ensure durability in humidity and acid rain.

Zero Maintenance: No need for regular cleaning due to strong anti-fouling ability and self-cleaning properties.

Certified Quality: Complies with CCC, CE, ISO9001, IEC, ANSI, and GB international standards.

Customizable Design: Special designs available according to customer requirements for insulation and coupling.

Reliable Sealing: Internal radial multi-seal structure guarantees long-term reliability at connection points.

AI-Powered supplier vetting

SummaryThe supplier is identified as a combined manufacturing, processing, and sales business in Yueqing, Wenzhou, focused on power-distribution and insulation products. It has valid manufacturing-capacity contracts with associated subcontractors, five production lines, documented inspection procedures, and stated annual output across surge arresters, power fittings, switches, insulators, and fuse cutouts. Quality systems include one listed QA/QC inspector, written corrective-action and complaint-handling procedures, and quality assurance. The supplier provides ODM, OEM, sample-based customization, and an SDK, but reported no new products during the past year. It lacks inventory, overseas warehouses, overseas agents or branches, and overseas showrooms; it has participated in the Dubai Exhibition. Financial records are identified for multiple years, but their results are not provided. No certification information or specific customer cases are documented.

Supplier typeThe supplier is described as a combined company with a business scope covering manufacturing, processing, and sales of power-distribution switch control equipment, insulation products, fuses, lightning arresters, transformers, wires, and cables. Its company nature is separately recorded as a trading company, so the available records indicate a mixed manufacturing/trading profile rather than a purely manufacturing entity.

After-Sales capabilityThe supplier has documented procedures and followed records for handling customer complaints and corrective/preventive actions, indicating an established service-response process. However, it lacks in-stock service capacity, overseas warehouses, overseas agents or branches, and overseas showrooms, while its overseas service coverage is recorded as zero countries.

R&D capabilityThe supplier has an available SDK and provides ODM services, demonstrating some product-development and design-service capability. Nevertheless, it explicitly reported no new products during the past year, which limits evidence of recent innovation activity.

Production capacityThe supplier has valid manufacturing-capacity contracts with associated subcontractors, operates five production lines, and reports substantial annual production quantities across five product categories. Finished-product inspection follows written and uniformly applied instructions, although only one QA/QC inspector is listed and the quality-control staff count is recorded as fewer than five.

Customization capabilityThe supplier offers ODM services, OEM capability for popular brands, and design customization from samples. These explicit service offerings support a demonstrated ability to adapt products to customer or brand requirements.

Product Q&A

Q:What are the main advantages of composite insulators for railways?

They feature compact structure, strong integrity, light weight, good anti-fouling ability, and high mechanical strength. They require no regular cleaning and effectively prevent pollution flashovers.

Q:What materials are used for the housing and rod?

The housing is made of silicone rubber with good hydrophobicity. The rod is modified ECR fiberglass reinforced epoxy resin with high tensile strength (>1200Mpa) and resistance to stress corrosion.

Q:Is customization available for these insulators?

Yes, special designs are available according to customer requirements. Customization options include insulation material and type of couple.

Q:What is the minimum order quantity?

The minimum order quantity is 1 Set.

Q:What are the payment terms and lead time?

Payment terms are LC or T/T. The average lead time is one month for both peak and off-season.
