Heavy-Duty Composite Suspension Insulator

FU120B is presented for overhead lines where mechanical tension is comparatively high and the insulator must provide both mechanical connection and electrical isolation.
The documented use cases include projects affected by conductor tension, strong wind, heavy icing, and external-insulation requirements.
A Heavy-Duty Composite Suspension Insulator may be specified at either suspension or tension positions when the line design calls for this heavier-duty construction.

How the Load Path Is Built

The principal mechanical element is a high-strength core rod connected to the end fittings.

A composite shed system forms the external insulation around the load-bearing core.

The supplied data does not state a numerical mechanical-load rating for FU120B, so the required project load must be confirmed from the buyer's technical conditions.

Technical Inputs for Custom Work

OEM/ODM production can start from a line design drawing, project technical requirements, or an existing sample.

The key discussion points are mechanical requirement, end fittings, core-rod size, structural length, creepage distance, minimum arcing distance, and line voltage.

Custom sample development is stated as 30 working days. Drawing or sample approval can also be arranged before mass production.

Release Inspection for Heavy-Load Orders

Quality management includes raw-material control, process supervision, finished-product outgoing inspection, and after-sales traceability.

Technical documents and test support can be prepared according to the confirmed customer and project specification.

Bulk products receive 100% inspection before packaging, with third-party inspection accepted.

Packing and Execution

Packing is planned around overall length, end-fitting geometry, and the receiving requirements of the destination country.

The stated production cycle is about 30 days for standard products and about 45 days for customized products. Photo or video progress reports may be provided while the order is in production.

EXW, FOB, and DDP are available trade terms.

For the Heavy-Duty Composite Suspension Insulator, submit the project mechanical requirement with the line drawing so FU120B is evaluated against actual service conditions rather than inferred from the model code.
