Glass insulators technical features:
The unique performance of Orient glass insulators combined with the intrinsic properties of toughened glass makes them the most attractive insulators in term of life cycle costs:
No ageing
Infallible & easy visual inspection
Safe live line working

Orient Glass insulators technical features: No ageing and How is it achieved?
The toughened glass shell is immune to the effects of micro-crack propagation with time and load / temperature cycles. No other insulator dielectric behaves in the same way.
The hot cured alumina cement used in Orient glass insulators is very strong, stable, and immune to any cement growth phenomena.
A highly automated manufacturing process, perfected over the years by Orient, guarantees an extremely homogenous and consistent high level of quality in the materials and the final product assembly.

Orient has performed many studies on insulators returned after decades of service in all kinds of environments which have shown no mechanical or electrical change in performance, even after 40 years in service.

Glass insulators technical features: Infallible & easy visual inspection
With toughened glass, if the skirt is visible the insulator is as good as new.
Whereas inspecting cap and pin porcelain insulators are known to be a very difficult and costly exercise (climbing towers, buzzing each unit...), and is often impossible with composite insulators; a simple visual glance at a toughened glass insulator string gives a complete and reliable assessment of its integrity.
Toughened glass insulators cannot be punctured nor be internally cracked: a damaged glass shell will instantly reveal its condition by shattering into small fragments. Since the mechanical strength of Orient “stub” is almost unchanged compared to an intact insulator, there is no need to anticipate any special maintenance operations.
The decision to replace a stub is related to local maintenance procedures of each Utility but it is not a consequence of technical or safety issues.

Glass insulators technical features: Safe live line working
With the economical challenge of service dependability which requires maintaining lines in operation, it is clear that live line work has become an absolute necessity to most Utilities.
But live line maintenance requires specialized crews, equipment and complex procedures where the first step is to make an assessment of the condition of the insulator strings; Who would dare to take a risk with maintenance crews performing such live line maintenance on insulators whose real integrity is not 100% sure?
With Orient glass insulators: no such risk. A simple visual glance at the string gives a complete and reliable assessment of the condition of the insulation.
