HIVOLT toughened glass have different style of insulator sheds
profile designs:
we design insulator shed profile based on different working
conditions :
for example : light pollution area , midum pollution area , heavy
pollution area or coastal area etc.
Standard shed profile
This profile has a leakage distance in excess of standard duty. The
standard profile insulators all meet ANSI C29.2 & CSA.
Spherical type shed profile
The leakage distance of this profile is equivalent to that of
standard
profi le type. The absence of under-ribs reduces pollution
build-up. It
also facilitates self-cleaning on washing in dust-laden
environments.
Fog type shed profile
This profi le has an extra-long leakage distance obtained by ribs
of
greater depth. The profi le and wide spacing of the ribs promote an
effective self-cleaning and facilitate washing. Their wide spacing
also
prevents arcing between adjacent ribs under severe contamination.
we also have another optional design for this condition for example
:
double layers shed profile , that means glass body including 2
layers or 3 layers,
which not only provide anti-fog character , but also can working in
heavy rain place .
it will bring excellent wet condition electrical performance.
Open type shed profile
The absence of deep under-ribs on this shell type which reduces
pollutant accumulation on the lower surface .
because air flow is smooth and uninterrupted. This design is
particularly effective in desert areas
where natural washing by rain is infrequent.
Competitive Advantage:
The glass insulators has good advantage for example :mass
production in auto- production lines , and insulation body of glass
component are even and easy for quality control .the unqaulifed
parts are recyclable, so it will save cost to provie more
reasonable price for end users.
Product quality are very reliable .
insulator shell surface are very smooth and free of visual defect ,
and easy for maintance in high pollution areas . we offer very
competitive price . High quality , best competitive is our goal .
