Epoxy Resin Treated Fiberglass Web Unidirectional Banding type
Epoxy Resin Treated Fiberglass Banding Tape with web structure is an ideal banding material for applying to the electrical machines and transformers. This banding tape is not only oliable and slightly tacky but also can be unwinded freely fron the spool without glass strands, separation and overlapping. When it is pulled open the web structure will appear and the width of the tape may be extended to over twice the size of the original. It also can be storaged for one year at the temperature of 5C. In addition this product possesses its distinctive characteristics of high tensile strength high resistance to shocks high moduius of elasticity and low percent elongation at Break as well no magnetically-confining and eddy losses.
Banding armature of rotation electrical machines or blocking frans former colums is not the only use of this tape. It is further indicated for applying to the large-scale and special type electrical machines etc. It’s pull when banding can reach the maximum value of 100N/mm. |
