Continuously Transposed Conductors –
Part 3. 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.
