Product Description

SASUN , Experts and pioneers in insulation technology

With 20 years of experience and investment in R&D, SASUN has gained uncontested expertise in research, design, manufacturing and testing of insulators for power networks up to very high voltages and for railway catenary systems. SASUN is the partner of choice for all insulation applications.

Research & Development, a permanent and continuous investment

Always on the lookout for continuous technological improvements, SASUN heavily invests in Research and Development. Our research and testing facilities as well as our high voltage CEB laboratory both located in France boast state-of-the-art equipment that allows extensive research programs as well as testing of complete strings for systems up to 800 kV.

Unique manufacturing processes

SASUN manufacturing processes are unique in the world.

These processes have been developed and improved thanks to the experience SASUN has gained over the years following-up and assessing the performance of millions of insulators in service as well as through the integration of the latest technological advances.

Our goal: your satisfaction through the reliability of our products on your lines.

SASUN toughened glass suspension insulators

Standard profile:

The standard profile is characterized by a leakage distance* higher than the values indicated in the IEC 60305 for standard insulators and by shallow and well-spaced under-ribs that allow an effective self-cleaning action by wind or rain. It features a “leakage distance/spacing” ratio of around 2.2 and is particularly effective in suspension and tension applications in very light to medium polluted areas where typically the pollution level (ESDD) is lower than 0.1 mg/cm2.

Fog type profile:

The fog type profile is characterized by long and widely-spaced under-ribs so as to avoid arc bridging between adjacent ribs. It features a « leakage distance/spacing » ratio of around 3.2 and is particularly effective in coastal areas (Salt fog) as well as in polluted areas where a higher specific leakage distance is required.

Open profile:

The open type profile features a « leakage distance/spacing » ratio of around 2.4, with no under-ribs so as to avoid the accumulation of solid pollution deposits (dust, sand) on its lower surface. It is particularly adapted to suspension and tension applications in desert areas where wind is predominant and rain infrequent.

It is also effective for dead-end strings in cases of extreme industrial pollution and can solve ice-bridging problems when it is alternated with other profiles in the string.

External shed profile:

This profile offers a leakage distance equivalent to the anti-pollution profile and is adapted to the most extreme cases of solid pollution.

The elimination of the under-ribs reduces pollution build-up, promotes self-cleaning and facilitates manual cleaning when necessary.

Packing and palletization

Reinforced and optimized packing

The packing and palletizing methods used by Sediver® result from the experience gained from the shipment of hundreds of millions of toughened glass insulators to users’ warehouses and construction sites in 150 countries as well as from extensive tests performed by packing research organizations.

The packing methods described and illustrated below have been developed expressly to minimize any possible damage during shipment and storage.

The wood used for packing is either standard or treated according to country regulations or/and customer specification.
