The product is a graphite plate designed for use in surge protection devices (SPD). It is manufactured from high purity carbon graphite with a carbon content of 99.5 % or higher and is formed by isostatic pressing. The plates are precision‑machined to meet the electrical and thermal requirements of voltage‑spike dissipation. Supplier Pingdingshan Dingjingxin Industry & Trade Co., Ltd. produces the plates in a range of sizes according to buyer drawings.
Graphite’s intrinsic high electrical conductivity and low thermal expansion make it suitable for rapid discharge and heat removal in SPD assemblies. Typical industry plates have thicknesses between 5 mm and 20 mm and densities around 1.9 g cm‑3, providing a balance of mechanical strength and conductivity. The isostatic pressing process yields a uniform grain structure that reduces internal stresses during high‑voltage events. Compared with metal gaps, graphite gaps avoid plasma formation, improving device stability.
Manufacturers of lightning protection systems, power distribution equipment and industrial electrical enclosures commonly source these plates in bulk. Orders are usually shipped FOB or CIF from ports in China, with packaging in reinforced wooden crates to protect the plates during transit. Custom dimensions and tolerances can be confirmed during the quotation stage, and the supplier offers test reports on conductivity and thermal resistance upon request. Buyers should verify the supplied material certificate and ensure compliance with relevant IEC standards.

Before placing an order, importers should request the material certificate confirming carbon content of at least 99.5 % and a density test report. The buyer should also obtain a drawing‑approved sample to validate dimensional tolerances and surface finish. It is advisable to clarify whether the supplier can meet any specific IEC‑related testing requirements and to agree on the acceptable range for thickness and resistivity. Documentation of these parameters reduces the risk of non‑conforming shipments.
Logistics for the graphite plates are typically arranged from major Chinese ports such as Shanghai or Tianjin under FOB or CIF terms. While the listing does not state a fixed lead‑time, buyers should ask the supplier to confirm production scheduling and expected shipment duration. Common payment methods include T/T, L/C and Western Union, but the exact terms must be negotiated prior to contract signing. Clarifying the incoterm and insurance coverage will ensure smooth customs clearance.
Quality assurance generally involves dimensional inspection, surface roughness measurement and electrical resistivity testing performed by the supplier’s laboratory. Importers may request a third‑party inspection agency to verify these parameters before loading. The supplier should provide test reports, material safety data sheets and, if available, compliance certificates with IEC standards. Retaining these documents facilitates product acceptance at the destination and supports any post‑delivery warranty claims.
