22.214.171.124.2 Applicable entities
|Name||Property Type||Data Type||Description|
The current that a device is designed to handle.
The range of allowed voltage that a device is certified to handle. The upper bound of this value is the maximum.
The insulation voltage.
The max voltage for normal insulation operation.
Nominal value of the spark gap breakdown voltage tolerance.
The method used to insulate.
The temperature range in which the device operates normally.
Shortest distance or the sum of the shortest distances along the surface on an insulator between two conductive parts which normally have the operating voltage between them. (IEV ref 471-01-04)
Method of installation of cable/conductor. Installation methods are typically defined by reference in standards such as IEC 60364-5-52, table 52A-1 or BS7671 Appendix 4 Table 4A1 etc. Selection of the value to be used should be determined from such a standard according to local usage.
The peak lightning voltage that the insulator could withstand.
Rms value of sinusoidal power frequency voltage that the insulation of the given equipment can withstand during tests made under specified conditions and for a specified duration. (IEV ref 614-03-22）
The actual voltage and operable range.
