Corona Ring
Shijiazhuang Huaneng Electric Power Fitting Co., Ltd. manufactures a Corona Ring, an annular metal component mounted on the ends of bushings and insulator strings to suppress corona discharge in high‑voltage transmission lines. The ring’s smooth circular shape spreads the electric field, keeping the potential gradient below the critical destruction voltage of roughly 30 kV/cm. The supplier notes that aluminium rings are typically installed on lines above 230 kV and on both ends of insulators for 500 kV systems.
In the industry, corona rings are usually fabricated from aluminium alloy, often 6061‑T6, because of its conductivity and corrosion resistance. Standard outer diameters range from 250 mm to 350 mm, with a typical weight of 4 kg for a 300 mm ring. Surface treatment is commonly anodised to withstand outdoor exposure, and the rings are designed to meet IEC 60071 standards for high‑voltage equipment. These typical specifications complement the supplier’s description of the product’s function and recommended voltage levels.
Transmission utilities and line‑construction contractors purchase the rings to improve line efficiency and reduce power loss caused by corona. The supplier does not list specific packaging, lead‑time or payment terms, so buyers should request those details directly. Confirm the material grade, dimensional tolerances and any required certifications before finalising a purchase to ensure compatibility with existing infrastructure.

Sourcing Corona Ring from Shijiazhuang Huaneng Electric Power Fitting Co., Ltd. - China Import Guide
Verify the exact aluminium alloy, outer diameter and surface treatment before confirming the order. Request any applicable certifications, such as IEC 60071 compliance or ISO 9001, and obtain a mill test certificate that documents material properties and dimensions. If custom dimensions are required, obtain a written engineering drawing and agree on the tolerance limits.
Discuss logistics early: ask the supplier to confirm the preferred incoterm, typical packaging format and expected lead‑time for the quantity you need. Payment is usually arranged by T/T, but you may negotiate a letter of credit or escrow arrangement to protect both parties. Clarify whether the supplier can provide freight forwarding assistance or if you will arrange shipping independently.
Plan a quality inspection strategy that includes visual checks for anodised coating, dimensional verification with calipers, and electrical testing to confirm corona suppression performance. Request a factory‑acceptance test report and a certificate of conformity with IEC 60071. Ensure that the commercial invoice, packing list and certificate of origin are prepared for customs clearance in your importing country.
