23、 the definitions of EN 50290-1-2 apply. 1)At draft stage. 5 EN 50289-4-14:2003 4 General A direct lightning strike can cause an enormous amount of physical damage. However, the indirect effects from a nearby strike can also cause damage by inducing voltage surges onto cables. A guide for the selecti
24、on of protective measures is given in IEC 61663-1 and in IEC 61663-2. However, in some cases, compliance with ITU-T K 20 may be requested. The end user should be aware that the conditions of installation can influence the actual behaviour under lightning exposure of the installed cables. EN 50174-2
25、and EN 50174-3 give further information about installation practices. 5 Test method Although a general test is under consideration, OPGW and OPPW cables shall be tested according to IEC 60794-1-2 (EN 187200). 6 Requirements Under consideration. 7 Test report Under consideration.
