Quality driven organization and staff

Ideally, an insulator once installed, should be maintenance free and forgotten by the operator of the line for several decades. Sediver contributes to achieving this goal by placing quality at all levels of the organization and at the forefront of the actions undertaken by all personnel. The Sediver quality system covers all products and activities from the design, manufacturing, testing and supply, up to after-sales service.

Quality of products

Each factory quality organization is coordinated through a centralized Quality Department who acts as the client’s representative in determining and assuring full compliance of the manufactured insulators with the highest standards. Each quality department has absolute authority to ensure that the overall quality policy is enforced and respected at all levels of operations.

Quality of technical support

A team of skilled engineers operating in our Product Engineering Dept are dedicated to providing solutions to customers in the field of high-voltage insulation and protection. Their know how is based on 60 years of experience, testing and research carried out in state of the art laboratories using cutting edge technology in the fields of material science and mechanical and HV testing, including pollution testing and 3D electrical and mechanical simulations.

Long term performanceThe direct injection molding process used by Sediver offers a unique quality of interface between the rod and the housing as well as between the end fitting and the housing. Making the insulator fully “impenetrable”, this feature also offers unparallel quality of bonding along the rod preventing any risk of internal tracking along the longitudinal interface of the composite insulator.

Sediver unique combination between design features ... and manufacturing process

Sediver « Impenetrable » design proven dependability

Injected housing moulded directly to the rod and the fittings forming an impenetrable protective housing

End fitting attached to rod by compression crimping process which is acoustically monitored to ensure consistent performance

Bonded interface between rubber and metal fitting - no seals

All Sediver composite insulators are manufactured at high pressure and high temperature thanks to direct injection molding technology. This unique “impenetrable” housing design safely protects the fiberglass rod against water or contaminant penetration without the need of any “seals”. Injection molding technology has been adopted and continuously perfected by Sediver since 1985.

The Sediver state-of-the-art insulator is made with the most advanced materials, resulting from extensive research testing and field experience gained over more than 50 years of expertise in overhead line insulation.

Field experience has clearly demonstrated that composite insulator's performance and degradation is directly related to some key design features. One of them, (provided material selection is adequate),

is defined by the method of construction of the housing. In this regard, internal tracking and moisture penetration are known to be the main actors for failures in service. To prevent such risks, Sediver's housing is directly injected at high temperature and high pressure on the fiberglass rod and the fittings, assuring a complete adherence and strong bonding of the rubber.

The perfect bonding between rod and housing will not allow any development of internal tracking under the housing. The complete adherence of the rubber on to the end fitting enlarged collar eliminates the need for inherently weak sealing devices responsible for moisture ingress, and subsequently brittle fractures. The housing being totally “impenetrable” will also prevent possible moisture penetration along the core.

Mechanical ratings and definitions

Sediver line post insulators are available with core diameter of 1.75" to 3.5". Applications curves taking into account tri-dimensional loading are available upon request.

Specified Cantilever Load (SCL): cantilever load rating when tested in accordance with ANSI C29.17-2002.

Specified Tensile Load (STL): tensile load rating when tested in accordance with ANSI C29.17-2002.

Maximum Design Cantilever Load (MDCL): maximum cantilever load which causes no damage on the insulator. It is set at 50% of SCL.

�

Interface integrity monitoringThe longitudinal interface along the fiberglass rod and the rubber housing is highly critical in regard to risks of internal tracking if this interface is not perfectly bonded.

Thanks to the injection molding process, the Sediver design offers the strongest possible bonding and adherence between these two components.

Additionally, Sediver designed an exclusive non destructive testing method based on ultrasonic techniques to validate, on a sampling basis, the quality of this interface.

This control performed on finished products ensures the highest level of dependability of our polymer insulators.

Sediver unique combination between design features ... and manufacturing process

Fiberglass reinforced epoxy resin rod

Galvanized end fittings designed to reduced the E-field and provide a large surface rubber bonding

Housing material

Sediver line post insulators are available either with EPDM or with silicone rubber housing.

• EPDM compound has been specially formulated to provide optimum weathering and electrical properties for all operating conditions. Sediver has more than 30 years of excellent field experience with EPDM insulators over a wide range of pollution levels.

• Silicone compound provides excellent hydrophobic and recovery characteristics which limit leakage current and arcing in polluted or seacoast environments.

Both Sediver rubber formulations are the result of extensive research and testing programs.

Core: pultruded rods made by impregnation of high quality fiberglass with epoxy resin.

End fittings: hot dip galvanized steel, ductile or malleable cast iron for applications under severe environmental conditions.

Bases: hot deep galvanized rolled steel for bendable bases and ductile or malleable cast iron or steel for rigid bases.

Grading rings: • high grade aluminum alloy for the ring • hot dip galvanized steel for the bracket and supporting horn • stainless steel for bolts and nuts

Grading rings At higher operating voltages, grading rings are necessary to reduce the voltage gradient on and within the insulator, and to reduce radio noise to acceptable levels. As on ceramic strings, the need for grading rings also depends on admissible hardware design, conductor bundle position, altitude and contamination conditions. General recommendations for Sediver line post insulators used in non-contaminated and low altitude (<3000’) areas are:

Packing

Sediver composite insulators are packed in wooden crates. The inner part of the crate is lined with a plastic film to avoid a direct contact of the polymeric housing with the wood. Within the crate, each layer of insulators is supported by wooden separators to avoid damage of the insulator sheds, either from the weight of the insulators stacked above or during shipping.

Sediver composite braced line post insulators and horizontal Vees

Braced line post Pivoting horizontal Vee

Pivoting horizontal Vee with boomerang

Braced line posts are designed for applications similar to a line post but with an added suspension insulator or "brace" to increase the vertical load capacity of the assembly.

The pivoting horizontal Vee is similar to a braced line post except that instead of a fixed base, it is equipped with a hinged (pivoting) base thus preventing bending of the post insulator, thereby increasing its axial compression load capacity. This provides the horizontal vee assembly with a large vertical load capacity. The hinged connections allow it to efficiently redistribute unbalanced longitudinal loads in the conductor (such as due to non-uniform ice accumulation) and minimize torsional loads on the support structure.

The mechanical performance of the pivoting horizontal Vee can be further enhanced by the application of a boomerang type fitting at the line end. The boomerang will assure a concentric axial load in the line post insulator under any loading condition (angle structures, strong lateral wind, etc...).
