Less Paper Insulated Netting-Typed Continuous Transposed Conductors of Polyvinyl Acetal Enamelled Copper Wires 1 Scope This Part of JB/T 6758 specifies the general requirements for less paper insulated netting-typed continuous transposed conductors of polyvinyl acetal enamelled copper wires. The continuous transpose conductor core adopts Grade-120 self-adhesive polyvinyl acetal enamelled rectangular copper wire (thermosetting epoxy resin self- adhesive layer); mesh rope netting type adopts polyester fiber rope netting; grid netting type adopts polyester fiber nonwoven strip, epoxy resin glass fiber cloth strip or perforated insulating paper strip lapping. Copper conductor can be either ordinary soft copper wire or semi-hard copper wire. This Part shall be used in conjunction with JB/T 6758.1. 2 Normative References The provisions in following documents become the provisions of this Part through reference in this Part of JB/T 6758. For dated references, the subsequent amendments (excluding corrigendum) or revisions do not apply to this Standard, however, parties who reach an agreement based on this Standard are encouraged to study if the latest versions of these documents are applicable. For undated references, the latest edition of the referenced document applies. GB/T 4074.2 Test Methods for Winding Wires – Part 2.
