防爆尾端盒是按照國標GB3836.1-2000；GB3836.3-2000《爆炸性環境用防爆電氣設備  第1部分：通用要求、第2部分：增安型“e” 》的有關規定設計制造的。防爆等級ExeⅡT4，適用于工廠一區、二區爆炸性氣體混合物T1-T4的溫度組別場所。Explosion-proof terminal kit is also designed as the requirement of GB3836.1-2000 and GB3836.3-2000. ExeⅡBT4 is suitable for hazardous area(Division 1&2), T1-T4.
 
1結構原理Structure Principle
WH防爆尾端盒分上、下兩個盒體，它用于電熱帶的末端，使用電熱帶末端與外界隔絕，下盒腔內有隔板，使用電熱帶母線末端可靠隔開。WH terminal kit has two parts, using for insulating the end of the heating cable. The lower part can reliably separate the ends of heating cable.
