A19790414说的条文:
! D; ^2 x! {) J& M8 C" V! {) b; f6.9.6 An insulated conductor, including each insulated conductor of a cord, that is rated for 90 °C, 105°C, or 125 °C shall be considered as rated for 150 °C if each conductor is individually provided with supplemental insulation consisting of snugly fitting woven glass fiber sleeving having at least a 0.25 mm (0.010 in) wall thickness or at least two layers of glass fiber tape that provide a total thickness of at least 0.25 mm (0.010 in).
3 f3 I+ H1 H; nsnugly fitting woven glass fiber sleeving 应该是指那种表面织有玻纤套管的电线。
$ }8 R+ J+ l4 S另外
. F/ H2 [1 ~, Y4 V5.18.1 Thermal insulation shall be fire-resistant material, such as glass fiber, inorganic material, or polymeric material.
