38、es to rigid HV gas-insulated transmission lines (GIL) in which the insulation is obtained, at least partly, by a non-corrosive insulating gas, other than air at atmos-pheric pressure, for alternating current of rated voltages above 52 kV, and for service frequencies up to and including 60 Hz. It is

39、intended that this international standard be used where the provisions of IEC 62271-203 do not cover the application of GIL (see NOTE 3). At each end of the HV gas-insulated transmission line, a specific element may be used for the connection between the HV gas-insulated transmission line and other

40、equipment like bushings, power transformers or reactors, cable boxes, metal-enclosed surge arresters, voltage transformers or GIS, covered by their own specification. Unless otherwise specified, the HV gas-insulated transmission line is designed to be used under normal service conditions. NOTE 1 In

41、this international standard, the term “HV gas-insulated transmission line“ is abbreviated to “GIL“. NOTE 2 In this international standard, the word “gas“ means gas or gas mixture, as defined by the manufacturer. NOTE 3 Examples of GIL applications are given: where all or part of the HV gas-insulated

42、 transmission line is directly buried; or where the HV gas-insulated transmission line is located, wholly or partly, in an area accessible to public; or where the HV gas-insulated transmission line is long and the typical gas compartment length exceeds the common practice of GIS technology. 1.2 Norm

49、 Clause 2 of IEC 62271-1 is applicable with the following addition: At any altitude the dielectric characteristics of the internal insulation are identical with those measured at sea-level. For this insulation, therefore, no requirements concerning the altitude are applicable. The normal service conditions which apply to a GIL depending on the installation conditions are given in 2.101, 2.102 and 2.103.
