FAQ

Is high-voltage testing used for THHN?

Electrical insulation tests are part of wire qualification and quality-control programs. The exact test method and voltage depend on the applicable standard and production process. For international orders of THHN dielectric test, GERITEL WIRE can coordinate technical confirmation, color and size selection, printing, packing and shipment documentation.

Is tensile strength of the insulation important?

Mechanical properties such as tensile strength and elongation help demonstrate that the insulation materials have the required durability before and after conditioning. GERITEL WIRE can support THHN insulation tensile test distributors and contractors with product-data confirmation, OEM requirements, batch identification and export-ready packing.

Does heat aging matter for THHN?

Yes. Heat-aging evaluation helps confirm that the insulation system retains acceptable properties after elevated-temperature exposure. GERITEL WIRE supports THHN heat aging test project inquiries with specification review, OEM marking discussion, reel or coil planning and export documentation.

How is wet performance evaluated?

THWN-2 has wet-location requirements, so the product must meet the applicable electrical and material performance criteria associated with that rating. Buyers evaluating THWN-2 wet performance can work with GERITEL WIRE on document review, sample confirmation, project quantities and repeat-order consistency.
