防爆密封接头的材质是铜合金,黄铜镀镍,不锈钢由于铜与优质不锈钢的良好导热性能及几乎不含碳的特质,使接头与物体摩擦或撞击时,短时间内产生的热量被吸收及传导,另一原因由于铜与不锈钢本身相对较软,摩擦和撞击时有很好的退让性,不易产生微小金属颗粒,于是我们几乎看不到火花,因此来达到防爆的效果。 主要适用范围是:石油精炼和石油化学工业、煤矿、油田、天然气化学工业、化纤工业、油漆工业、肥料工业、各种药品工业。石油轮和液化石油气的车辆、经营易燃易爆品的仓库、电解车间、通讯机装配车间、要求接头不生锈、耐磨抗磁的场所等。 适用范围' 适用于夹持和固定各种类型的钢丝铠装电缆 ; 隔爆要求,要求壳体密封达IP66的场所。 Applying scope Suitable for clamping and fastening various kinds of steel wire armored cables; Flame-proof requirement: It should be used on enclosure with IP66 degree of protection. 技术数据 防爆标志:ExdII、ExeII; 标准工作温度范围:-60℃~+100℃; 防护等级:IP66; 密封接头的设计符合GB3836和BS6121。 Specification Ex-marking: ExdII, ExeII; Standard working temperature scope: -60℃ 100℃; Degree of protection: IP66; The design of cable gland is in accordance with GB3836 and BS6121. 结构特点 本产品具有安装使用方便,能直接用电缆的铠装层提供可靠的接地,适用范围广泛,可靠性高的特点。 Structure and features It has features of convenient installation, wide application scope and high reliability, providing reliable earthing with cable armored layer 材料 1、采用黄铜或不锈钢以标准工艺制造,黄铜表面可钝化处理,也可镀镍。 Material 1、It is made of brass or stainless steel with standard craft.
