Camber strips shall not exceed 3 mm per 1 m length.
Camber strips up to 4.0 mm, should not exceed 5 mm to 1 m in length, thickness exceeding 4,0 mm - 8 mm to 1 m in length.
At the request of the consumer, strips for power capacitors and the transformer can be made from copper M1E Volume resistivity not more than 17,48 ∙ ∙ 10 -9 ohm m (0.01748 ohm ∙ mm 2 / m).
Surface quality:
The surface of the tape must be clean. On the surface, allowed discoloration, local darkening traces of technological lubricants, as well as local defects, not putting out tapes for control over clean-up tolerances in thickness.
Feeds up to 2 mm thick, designed for power capacitors and transformers, coils, shall have no burrs.
