Key features of Taporel Core Rods:<\/strong>
\n1. One of the manufacturers with strong capabilities in producing electrically insulated core rods, currently having 120 production lines.
\n2. In the manufacturing process of electrically insulating core rods, manufacturers who do not use the mold release agent production method are subject to the patent number ZL2006 10041850.1.
\n3. Manufacturers of electrically insulating core rods that have passed the type test conducted by the Dutch KEMA laboratory.
\n4. The acid-resistant (ECR) core rods of Tapry Electric have passed the 7,200-hour stress corrosion resistance test conducted by the Wuhan High Voltage Research Institute of the State Grid Corporation.
\n5. The electrical insulation core rods of Tapry Electric have been used on 1000KV AC power lines.
\n6. The electrical insulation core rods of Tapry Electric have been used on the transmission lines with a voltage level of \u00b11100KV for direct current.
\nThe execution standards for the Tapry electrical core rods are enterprise standards: Q\/TPR01-2018 and Q\/TPR02-2018 ECR.
\nWe will follow and implement the following standards, but some indicators will exceed these standards:
