Insulator 52 series

We offer ANSI standard suspension insulators , for example : ANSI 52-1 , ANSI 52-2, ANSI 52-9, ANSI 52-3, ANSI 52-4, ANSI 52-5 , ANSI 52-6, ANSI 52-7, ANSI 52-8 , ANSI 52-10, ANSI 52-11 etc. Those insulators mainly used in the market of USA , Canada , and Latin American countries. 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 & clevis HIVOLT 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.
