ПТнБвс (ПТнБнс ПТнБлс ПТнБпс) Type

ТТ 23.7-05755625-023:2013

ПТнБвс (ПТнБнс ПТнБлс ПТнБпс) Type is copper transposed conductor in partial paper insulation (the symbols «в»(н, л, п) «в» – the box is on top of the wire, «н» – bottom, «л» – left, «п» – right).

Conductors are manufactured with normed or non-normed yield strength (Rp 0,2) of copper wire (reinforced).

Range of yield strength, N / mm2:
110 ≤ Rp 0,2 < 140
140 ≤ Rp 0,2 < 170
170 ≤ Rp 0,2 < 190

The cross section of enameled wire should be no more than 20 m2 for wires with nominal yield strength of up to 170 N/mm2.

Application: conductors are used for manufacture of windings of high-voltage oil transformers and reactors. Conductors on heat resistance of insulation belong to the class A 105°С.
