Composite suspension insulators

Composite suspension insulators are impenetrable design and used for high voltage T & D system. Orient created the unique complete composite insulator that is impenetrable to humidity and moisture.

Composite suspension insulators

Composite suspension insulators impenetrable design:
By moulding the weathersheds directly onto the core and over the end fittings under high pressure and high temperature, Orient created the unique complete composite insulator that is impenetrable to humidity and moisture.

This perfect bond assures that even under high pressure water the sole interface of the insulator, the metal fitting / covering material to be as strong as the polymer itself. The fiberglass rod core remains encapsulated and protected from any ingression for a long term mechanical performance.

Orient state-of-the-art composite insulators are made by molding the weathersheds and housing directly onto the core and metal end fitting in a single step. The result is an impenetrable design that gives ultimate protection for the core.

High-strength, epoxy fiberglass core is completely protected from the elements along its length by a jointless, seamless, molded rubber housing.

Sheds with alternating diameters prevent birdging by ice, snow, and cascading rain.

Orient has developed a complete range of composite suspension insulators range of composite suspension insulators
Voltage application: 15kv up to 765kv (400kv line, 500 KV line)
Mechanical strength
40kn up to 600kn
Three different shed profiles
Giving necessary leakage distance to answer pollution conditions
Two types of covering materials:
Silicone rubber which minimizes leakage current and prevents arcing even in very polluted and salt water environments.
EPDM rubber which has proven its efficiency over a wide range of climates, contamination level and line voltage since 1975.

Grading ring:
Grading rings are required to reduce the voltage gradient on and within the insulator.
Power arc can be developed by the hom supporting the ring without damage to insulator having:
Coupling size 16 A: 20 KA 0.5s
Coupling size 20 A: 25 KA 0.5s
(1 shot, according to IEC 61467)

Packing:
The packing method described and illustrated has been developed to minimize possible damage during shipment and storage as well as to reduce space and freight cost.
Composite insulators are packed in reinforced wooden crates and are protected against moisture by a polyethylene film.
