Key features

Anti-Fouling Performance: Good anti-fouling ability and hydrophobicity prevent pollution flashovers, eliminating the need for regular cleaning.

Compact & Lightweight: Small size and light weight make it ideal for high-speed railways and tunnels where porcelain/glass insulators cannot fit.

High Mechanical Strength: Modified ECR fiberglass rod offers tensile strength >1200Mpa, ensuring high mechanical strength and internal insulation quality.

Corrosion Resistance: Stainless steel or hot-dip galvanized cast steel support arms provide excellent anti-corrosion performance against acid rain and humidity.

Customizable Design: Special designs are available according to customer's requirements, including color options like red, gray, and white.

Reliable Sealing Structure: Internal radial multi-seal structure and overall injection molding minimize interface issues, guaranteeing long-term seal reliability.

International Standards: Complies with IEC, ANSI, GB, and other international standards for safe operation of high voltage transmission lines.

OEM/ODM Service: Manufacturer offers OEM and ODM services with customization from samples, supported by dedicated R&D engineers.

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 electrified railways?

They feature compact structure, strong integrity, good anti-fouling ability, light weight, and high mechanical strength. They do not require regular cleaning and effectively prevent pollution flashovers.

Q:Can the insulators be customized?

Yes, special designs are available according to customer requirements. The normal colors are red, gray, and white, but customization from samples is supported via OEM/ODM services.

Q:What materials are used for the support arm and housing?

The support arm is made of stainless steel or hot-dip galvanized cast steel for anti-corrosion. The housing is silicone rubber with whole injection molding, offering good hydrophobicity and soil resistance.

Q:What is the tensile strength of the fiberglass rod?

The modified ECR fiberglass reinforced epoxy resin rod has a high tensile strength of greater than 1200Mpa, ensuring resistance to creep, fatigue failure, and stress corrosion.

Q:What standards do these insulators comply with?

The applicable standards include IEC, ANSI, GB, and other international standards.
