Abstract
Disclosed therein is an insulator, which includes an inner sheath formed in such a fashion that a binder, is soaked to a glass fiber mat having a multiple layer winding, the insulator comprising: a first reinforced layer accommodating the outer surface of the inner sheath, the first reinforced layer being made of one of flame-resistant polyurethane resin, in which polyol having flame retardant and isocyanate are mixed together, and melamine resin; and a first cover layer for accommodating the outer surface of the first reinforced layer.
Claims16
An insulator, which includes an inner sheath formed in such a fashion that a binder is soaked to a glass fiber mat having a multiple layer winding, the insulator comprising:
- a first reinforced layer (20a) accommodating the outer surface of the inner sheath (10), the first reinforced layer (20a) being made of one of flame-resistant polyurethane resin, in which polyol having flame retardant and isocyanate are mixed together, and melamine resin;
- and
- a first cover layer (30a) for accommodating the outer surface of the first reinforced layer (20a).
An insulator, which includes an inner-sheath formed in such a fashion that a binder is soaked to a glass fiber mat having a multiple layer winding, the insulator comprising:
- a second reinforced layer (20b) grounded to the inner surface of the inner sheath (10), the second reinforced layer (20b) being made of one of flame-resistant polyurethane resin, in which polyol having flame retardant and isocyanate are mixed together, and melamine resin;
- and
- a second cover layer (30b) for accommodating the outer surface of the inner sheath (10).
