The high tensile strength and thermal endurance of glass fibers enables Hesgon to manufacture tapes in minimal thicknesses. This allows design engineers more flexibility and enables them to increase copper content and power ratings in electrical apparatus.
Whether operating in high ambient temperatures or developing high internal temperatures in electrical equipment, Hesgon glass tapes are virtually unaffected. The thermal endurance is limited only by the resins or varnishes combined with tape. The fiberglass tape does not start to soften until 732oC. The high thermal conductivity and rapid heat dispersion of glass tape is also very important in electrical equipment.
The high tensile strength of glass tapes prevent breakage under conditions that might normally weaken other insulating tapes. Pound for pound, fiberglass yarns are twice as strong as steel. Hesgon glass tapes retain 50% of their tensile strength at 340oC.
Hesgon tapes are manufactured of 100% fiberglass yarns with a minimum amount of sizing thus allowing for good wet-out impregnation. All tapes are also available in our standard or custom finishes to achieve maximum results with all the various resins available.
CT Finish & CT Yellow
This is a weave-setting finish wherein the warp and filling yarns are slightly fused together to stabilize the weave pattern and minimize the shifting of yarns. The tape retains its original white color with CT finish and has a light yellow color with the CT Yellow finish. This finish reinforces the tape and better enables it to withstand the abrasion frequently encountered in any winding operation. This tape, along with a gilt edge finish, is our best product for increasing operator comfort since it minimizes fiberglass dust and its associated mechanical irritation problems.
