2.主要特性：(Main characteristic)
● 接线盒采用全灌胶进行密封，防水等级高，内部二极管散热效果好。
The junction box uses the glue to seal, the waterproof effect is better, the fitting
interior heat is better.
● 此款接线盒为三分体设计，电缆采用水平出线方式，客户布线时可以减少电缆弯曲应力，也可以节
省电缆使用量，降低组件功率的损耗，同时将“热斑效应”的影响一分为三，降低了高温对光伏组件的影响。
This junction box is a three-part design, and the cable adopts horizontal outlet mode, which
can reduce the cable bending stress, save the cable usage, reduce the power loss of PV module,and
divide the influence of "hot spot effect" into three parts. The influence of high temperature on
photovoltaic modules is reduced.
● 三分体结构设计可以有效的降低二极管表面的温度，确保光伏组件高功率、高电流输出，降低温度对功率的影响，
为大功率光光伏组件提供很好的解决方案。
Three-part design can effectively reduce the temperature on the surface of the diode, ensure the
high power and high current output of the PV module, reduce the influence of temperature on the
power, and provide a good solution for the high power photovoltaic module.
