【 摘 要 】

Requirements, placed by design engineers in relation to special castings, applied to gas filled high voltage switchgears PN-EN 50052:2002, are still higher. These demands concern to quality of machined sealing surface, assurance of castings leaktightness for a long time of operating and suitable strength during special bursting test. Manufacturer of such castings is obliged to use, among other things, high quality new alloy and guarantee proper metallurgical treatment and liquid alloy control during metal melting and preparation, before filling the moulds.
