Key features

Compact & Lightweight Design: Small size and light weight make it ideal for tunnels with limited clearance, replacing porcelain/glass insulators.

Superior Anti-Fouling Performance: Silicone rubber housing with good hydrophobicity prevents pollution flashovers, eliminating the need for regular cleaning.

High Mechanical Strength: Modified ECR fiberglass rod offers tensile strength >1200Mpa, ensuring resistance to creep, fatigue, and high stress.

Corrosion Resistant Structure: Support arms made of stainless steel or hot-dip galvanized cast steel provide excellent anti-corrosion in humid/acid rain conditions.

Customizable OEM/ODM Service: Special designs available according to customer requirements, supported by OEM and ODM services.

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

Low Maintenance Requirements: Good anti-fouling ability and durability significantly reduce the workload of cleaning and maintenance in complex environments.

Certified Quality Assurance: ISO9001 certified with 100% finished product inspection (visual & function) and traceable raw materials.

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.
