2/50.g. After static, mechanical load with 900 Nm, as shown the "Testing structure the static mechanic- al load", the insulated conductor connected with an air-insulated comparative spark gap impulse voltage 1. An evaluation the transition resistances and release torques the screw connections according IEC 62561-1 can only carried out after the high-voltage test. this arcs and not the high-voltage-resistant, insulated conductor paral- lel, equivalent separation distance (se) cm can proven for this conductor type.g. with 200 kA Testing structure during impulse voltage test with an equivalent separation distance (se ) cm.2. Before this type test, three samples tested are subjected impulse cur- rent test with the indicated rated current, e. Further type tests are described IEC 62561-8 [Meppelink] and contain the following points: • Documentation • Labelling • Construction • Ultraviolet light • Tension and bend test • Corrosion • Impact test • Electrical testing with impulse current • Electrical testing with impulse voltage TBS Blitzschutz-Leitfaden 2018 / en / 2020/01/10 14:42:40 14:42:40 (LLExport_02613) / 2020/01/10 14:42:54 14:42:54 136 Chapter The external lightning protection system . 200 kA. The distance the comparative spark gap adjusted the distance the indicated separation distance using correction factor specified in the standard.13. Testing structure the static mechanical load An example the test structure shown, along with a registered load with disruptive breakthrough the comparative spark gap adjusted equivalent sep- aration distance (se) cm.6 Type tests for insulated conductors The recently published technical specification IEC TS 62561-8 specifies the requirements and type tests for insulated down conductors [Meppelink]. The key test is the proof the equivalent separation distance (se) of the insulated conductor. 2. Through three impulse voltage loads for each sample, it must proven that the comparative spark gap flashes over and disruptive breakthrough arcing occurs the insulated conductor.Structure insulated conductor test the lightning current carrying capacity, e. This proves the equivalent separation distance (se)
