Lightning Surge
Lightning surge resistors are tested in accordance with IEC 60 115-1 using both 1.2/50µs and 10/700µs pulse shapes. 10 pulses are applied. The limit of
acceptance is a shift in resistance of less than 1% from the initial value.

The single impulse graph is the result of 50 impulses of rectangular shape applied at one minute intervals. The limit of acceptance was a shift in
resistance of less than 1% from the initial value.

Continuous Load Due to Repetitive Pulses
The continuous load graph was obtained by applying repetitive rectangular pulses where the pulse period was adjusted so that the average
power dissipated in the resistor was equal to its rated power at 70°C. Again the limit of acceptance was a shift in resistance of less than 1% from the
initial value

如果主要市场保持目前的趋势，则2010年光伏装机市场或将增长60%。 这是iSuppli公司最新报告“PV Installations – A Global Rebound(光伏安装—全球性回升)”所做的预测。上述前景完全可能出现，因为我们没有在意大利、加州及整个美国、法国和西班牙看到任何不利因素。但如果德国、日本和中国目前关于光伏发电优惠和补贴政策的讨论结果不利，则光伏安装市...[详细]
