HIVOLT line post insulators 57-2 are suitable for vertical assembled on a wooden or steel crossarm .
HIVOLT line post insulator 57-2 are one solid piece porcelain . they are inherently free from radio interference without any treatment. their trim, sturdy sheds enable them to withstand attacks from stones , bullets and power arcover .
they are especially useful for service on industrial feeders where maximum reliability is most valuable in providing optimum service continuity.
on the tie top unit the wide ANSI standard wire groove is provided with a head and neck designed to enable the use of either warplock or standard wire ties.
we can provide short stud or long bolt for insulator assembly .
Applications:
The ANSI 57-2 porcelain line post insulators are used on distrbution lines . These insulators are commonly installed vertically on metal or wooden structures based to support the
conductor . tie top procelain can hold conductor firmly and suitable for different size of conductors.
Competitive Advantage:
high strength aluminum porcelain C-130 is used for insulation body .
the insulator have very light net weight yet high mechanical strength .
it can save transportation cost , and easy for assembly in distribution lines.
the insulator have excellent self-clean character , much easier for maintenance.
we offer 3 years quality guarantee .
OEM product are available .
