HIVOLT toughened glass offers below features:
High residual strength and no risk of line drop: Glass insulators
can only exist
in two well defined conditions: intact or shattered.There is no
intermediate cracked or punctured
state. Therefore it is easy to quickly inspect strings , with no
need for
additional test instruments, it will save more time and cost.
Safety in construction Because of the impossibility of inducing
hidden internal
damage, it is not possible to install a faulty string of glass
insulators. so it skips routine test before transmission line
constructions.
Puncture resistance glass insulators resist the most extreme surges
such as switching surges, steep front lightning strikes and power
arcs. There can be no hidden
puncture in a glass insulator.
Environmental Considerations Complete recyclability
toughened glass insulators are made of fully recyclable components,
so they do not represent a liability when retiring a line from
service.
Visual impact - toughened glass insulator easily blend with in the
sky
consequently have minimal visual impact once installed on any lines
Applications:
Glass insulator U240BP works as a part of string insulator in
transmission lines or substations up to 1000kV , the insulator can
assembled as suspension string or tension string with related
hardwares .
the insulator string can be single V string , double V string etc.
the fog type insulators are more popular used for heavy pollution
areas or coastal area.
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 .
