In high‑speed motors, large transformers, surge arresters and high‑reliability inductors, the choice of binding and insulation material directly determines equipment stability, service life and operational safety. For manufacturers and maintenance engineers worldwide, Hanyao Unidirectional Glass Fiber Tapes have become the trusted preferred solution, combining superior mechanical strength, reliable insulation performance, customizable grades and consistent factory quality.
Hanyao Unidirectional Glass Fiber Tapes feature parallel‑arranged continuous fiberglass filaments with tensile strength ≥800 MPa and elastic modulus 30–50 GPa. They withstand enormous centrifugal force in high‑speed motor rotors, firmly securing windings to avoid deformation or throw‑off. By replacing traditional metal retaining rings, they form a rigid, stable cured structure that greatly improves mechanical integrity and operation safety.
With a breakdown voltage ≥20 kV/mm and heat resistance grades up to 130℃, 155℃, 180℃, these tapes provide reliable insulation between coils while supporting long‑term high‑temperature operation. They improve overall insulation class (B/F/H) and heat dissipation, helping electrical equipment run more efficiently and last longer.
Made purely from glass fiber and resin, Hanyao UD tapes are non‑magnetic and produce no eddy current losses. They do not increase iron loss in motors, supporting higher energy efficiency and stable performance in precision and high‑speed electrical equipment.
Hanyao supports flexible selection to match different application needs:
Glass fiber: E‑glass for general high strength; S‑glass for ultra‑high mechanical demands
Resin: epoxy (high bonding, heat resistance, low shrinkage); polyester (fast curing, cost‑effective); modified high‑temp / tough resins
Sizes: width 10–30 mm, thickness 0.15–0.30 mm
Cured density 1.8–2.2 g/cm³ for balanced strength and weight
As a professional Chinese manufacturer of electrical insulation materials, Suzhou Hanyao provides one‑stop sourcing with stable batch consistency and reliable quality control. Committed to better quality and better service, Hanyao has earned long‑term repeat orders from global customers.
