TD28等电位联结端子箱产品概述
本产品适用于电设备的接地。各电子设备的独立保护接地(PE)和“工作参考地”均接至本箱，然后再独立引至接地装置，实现一点接地的要求（接地电阻
值由设计决定)。箱内还装有压敏电阻，一旦建筑遭雷击时，高电压击穿压敏电阻，把接在接地汇接箱板上的设备和建筑防雷接地连在一起，构成等电位跨接，
以保证设备和人身。
This product is suitable for grounding of electric equipment.Both individual protective earth and ?working reference filed?of kinds of electronic equipment areconnected to this box,then they are leaded to earth device separately,to get the aim of one-point earth (earth resistance value Is designed referring to design).
Furthermore,the box is set with varistor,in case that the building subjects to the thunder,the high voltage will break down the varistor,however,only the equipment connected toearth tandem box plate is connected with building lightning protection earth to form an equipotential bridge connection,the safety of both the equipment and human saf.
