Abstract

PURPOSE: To prevent the elution of oligomer into a refrigerant by coating the surface of polyethylene terephtalate film as aninsulating composition with a thermosetting resin excellent in anti-oligomer property.
CONSTITUTION: A tape, tube, sheet or the like made of polyethylene terephtalate film is applied by coating or wrapping around a strand 1 insulated as shown by 2 to make an earth insulation 3. In addition, the surface of the strand is coated or painted with a vanish, paint or the like made of polymide excellent in anti- oligomer property to form an anti-oligomer film 7. In this manner, even when an electric equipment is used in a refrigerant, oligomer in the polyethylene terephtalate is checked from eluting into the refrigerant, thereby eliminating the clogging of capillary in the freezing cycle and deterioration in lubrication property at the bearing of the rotary machine
