ANSI Standard Porcelain Suspension Insulators for Power Transmission

 IEC standard suspension insulator are also very popular, for example:U70BL , U100BL , U120BLP ,U160BLP ,U210B , U300B etc.Coupling method can be ball & socket or tongue & clevisHIVOLT product export to many of those countries , and have very good reputation just because we use high quality materials for insulators :1:  the insulator cap use high density ductile iron ,we test each piece of caps with magnetic powder testing method . the insulator pins are made of forged steel .the material can guarantee the inside of pin without any defects such as air , hole , crack etc.Both cap and pin are hot galvanized , zinc thickness meet ASTM 135 standard .2: we produce porcelain with high aluminum porcelain C120 . the porcelain surface covered a layer of hard glaze , color can be grey , brown or white or as per customer's specifications.3: the material of  R type locking pin is stainless steel which guarantee insulator string connection very safety .4: we use  excellent Portland cement to assemble insulation body with related cap and pins .    even after years of servicing , the cement still keep good performance./* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
