HIVOLT line post insulators 57-4 are available for vertical mounting in either tie top design.
the unit is vertical mounting on a crossarm .
HIVOLT line post insulator are one whole piece porcelain without joints . they are free from both radio and television interference without any further treatment. their trim, sturdy sheds enable them to withstand attacks from stones 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 ( N Neck) the wide ANSI standard wire groove is provided with a head and neck designed
we can provide short stud or long bolt for insulator assembly .
Applications:
The ANSI 57-4 porcelain line post insulators are used on distrbution lines with voltage up to 55kV. These insulators are commonly installed vertically on metal base 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 .
the insulator have excellent self-clean character , much easier for maintenance..
OEM product are available .
