Hollow Core insulators

Composite Hollow Core Insulators are a direct replacement of porcelain insulators used on substation apparatus applications. The applications, standards, design concepts, and other details are as follows.

Composite Hollow Core Insulators

Hollow Core insulators details:
The core of the product is the 1fiberglass tube made using electrical grade glass fibers and epoxy resin in a special “wet wind” filament winding process. The tubes are machined and fitted into high strength aluminum alloy flanges using a patented process that guarantees a gas tight and leak proof seal. The subassembly is then coated with silicone rubber weathersheds using a unique “spiral wrap” extrusion process, which allows insulators to be customized for virtually any application from 72 to 800kV.

Hollow Core insulators Applications:
Measuring Transformers
Cable Terminations
Optical Insulators
Live Tank Breakers
Dead Tank Breakers

Orient hollow core insulators are designed according to a selection of IEC and NEMA standards to assure long-term performance under normal and proper usage. The function and stresses are determined by the OEM and end-user specifications and meet applicable clauses of current composite insulator standards including IEC 60815 and IEC 61462.

Design Concepts:
In order to assure the best and long term performance, hollow core insulators are designed to perform mechanically, electrically, and environmentally according to specified requirements.
The hollow core insulators are designed to withstand maximum design stresses without affecting long-term mechanical performance, basically assuring that the maximum expected loads are below the damage limit of fibers and flanges.
The final electrical performance is guaranteed by the OEM. The hollow core insulator housing expected electrical characteristics are typically based on geometrical factors. The final design of Orient hollow core insulators has to meet the Orient criteria for long-term electrical and material performance.
The hollow core insulator weather sheds are made from an exclusive HTV silicone compound designed and tested according to IEC standards to withstand long term environmental conditions. Orient insulators have met the most stringent tests such as IEC’s long term aging tests and 5,000 hour weather cycling tests.
