Toughened Glass Insulators
Type : fog type & normal type
Class: up to 300 kN (E& M failing load value)
Standard: we can supply those insulators in IEC, ANSI , AU standards.
We can design insulators according to customer’s requirements.
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.
