Composite Anti Windage Yaw Insulator

The Composite Anti Windage Yaw Insulator is a wind-resistant composite jumper insulator designed to keep high-voltage jumper conductors stable under strong wind and reduce flashover risk caused by conductor displacement toward the tower or cross-arm. Built with a composite insulator body, silicone rubber full-skirt cover, upper and lower metal fittings, and in some designs grading rings, it is widely used in 35 kV to 330 kV overhead line systems. With options such as different section lengths, creepage distances, arcing distances, and a fiberglass core rod with high mechanical strength, it provides both reliable electrical insulation and improved mechanical stability for jumper sections exposed to harsh weather.

Product Accessories

Grading rings are used on selected designs to improve electric-field control at the end fittings, and the patent record for this product family specifically shows grading-ring placement at the upper and lower end fitting zones.

Connection hardware such as tower-side bolts, link plates, and clamp interfaces is used to match the insulator to the jumper arrangement and tower structure. The patent description shows a lower end wire clamp connection and a bolted upper connection to the tower side.

Coupling options are selected according to the project’s installation requirement, and the manufacturer datasheet lists coupling type as part of the order information.

Customized terminal fittings can be supplied to match customer requirements for jumper position, conductor size, and structure layout.

Product Applications

Economy is more affordable

where wind can pull the conductor toward the structure and reduce clearance. The product literature explicitly states this as its use case.

Hard jumper wires on high-voltage transmission lines
where windage-yaw flashover has been identified as an operating risk for overhead transmission lines.

Wind-prone line sections in strong wind and rain zones
where the line needs a stable insulated jumper span with controlled swing behavior. This matches the flexible wind-deflection-protection design concept described in the patent record.

Tower jumper assemblies at angle towers and dead-end points
in existing overhead networks that need a lighter composite solution with better wind-deflection performance. Manufacturer listings describe the product as a windbreak-style jumper insulator that can replace older jumper-insulator arrangements.

Product Advantages

Better wind-deflection control

The product is designed specifically to restrain jumper movement under wind load and reduce flashover risk.

Lightweight composite construction

The fiberglass-core and silicone-rubber design is easier to handle than heavier traditional insulators, while still offering the mechanical strength needed for jumper service.

Flexible project customization

Voltage class, section length, creepage distance, coupling type, and terminal fittings can be matched to the line design instead of forcing a one-size-fits-all layout.
