220kV GIS termination
Product Descriptions
● The whole dry structure is not filled with insulating oil, which overcomes the aging problem of stress cone caused by soaking in insulating oil, and improves the service life of stress cone and avoids leakage in operation.
● The surface of stress cone is attached to the epoxy resin insulator by a combined spring compaction device, which can keep constant interface pressure and overcomes the relaxation phenomenon caused by material aging of stress cone to ensure the safe operation of terminal.
● The product has the advantages of light weight, small volume, compact structure and convenient installation and maintenance.
● High-voltage metal shield electrode is embedded in epoxy resin insulator. Rubber stress cone adopts imported high-elastic liquid silicone rubber and optimizes the structure shape of stress cone product.
