Suspension Insulators

 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 many South 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.
