220kV dry type plug GlS terminal
Description
Product Features
The terminal is completely dry type structure, the internal is not filled with insulating oil, overcome the stress cone by soaking in the insulating oil aging, improve the service life of the stress cone, and avoids the terminal leakage phenomenon appeared in the process of running, is both environmental protection and free maintenance.
The combination of the spring pressing device, the application of cone surface close to the epoxy casing wall, can keep the interface pressure constant term, overcome the stress cone due to material aging phenomenon caused by the relaxation, to ensure the long-term and safe operation of the terminal.
Light weight, small size, compact structure, convenient installation and maintenance.
All the insulation parts are made of the factory, and the epoxy casing is embedded in the high pressure metal shield electrode. The rubber stress cone is used to import the high elastic liquid silicone rubber, and the structure shape of the stress cone product is optimized.
The main insulation parts have been tested in the factory according to the standard.
