防爆尾端盒是按照国标GB3836.1-2000；GB3836.3-2000《爆炸性环境用防爆电气设备  第1部分：通用要求、第2部分：增安型“e” 》的有关规定设计制造的。防爆等级ExeⅡT4，适用于工厂一区、二区爆炸性气体混合物T1-T4的温度组别场所。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结构原理Structure Principle
WH防爆尾端盒分上、下两个盒体，它用于电热带的末端，使用电热带末端与外界隔绝，下盒腔内有隔板，使用电热带母线末端可靠隔开。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.
