Each test piece shall be prepared from a 150 mm sample of completed cable.
The conductor screen test piece shall be prepared by cutting a sample of core in half
longitudinally and removing the conductor and separator if any (see Figure D.1a). The
insulation screen test piece shall be prepared by removing all the coverings from the sample
of core (see Figure D.1b).
The procedure for determining the volume resistivity of the screens shall be as follows:
Four silver-painted electrodes A, B, C, and D (see Figures D.1a and D.1b) shall be applied to
the semi-conducting surfaces. The two potential electrodes, B and C, shall be 50 mm apart
and the two current electrodes, A and D, shall be each placed at least 25 mm beyond the
potential electrodes.
Connections shall be made to the electrodes by means of suitable clips. In making
connections to the conductor screen electrodes it shall be ensured that the clips are insulated
from the insulation screen on the outer surface of the test sample.

1.每一個(gè)試驗(yàn)試樣都取自準(zhǔn)備的成品電纜試樣150mm
2.準(zhǔn)備導(dǎo)體屏蔽試樣,縱向切芯線屏蔽從導(dǎo)體上剝除,如果是絕緣屏蔽測試試樣,應(yīng)全部剝除(內(nèi)屏蔽半導(dǎo)電層),見圖D.1b
3.半導(dǎo)電屏蔽層絕緣電阻測試過程如下:
四個(gè)鍍銀電極A,B,C,D(見圖D.1b)應(yīng)適用于被測半導(dǎo)電體材料的表面特性。兩個(gè)電壓電極(B和C)需距離為50mm,兩個(gè)電流電極(A和D)分別在兩個(gè)電壓電極的后面距離25mm。
連接導(dǎo)體的電極應(yīng)由適合的夾具制作,連接導(dǎo)體屏蔽的電極應(yīng)確保與試樣的絕緣屏蔽的外表面是絕緣的。
水平有限,沒事給你翻翻。

導(dǎo)體屏蔽試樣的準(zhǔn)備:縱向切開芯線,剝除導(dǎo)體和隔離層(如有的話,見圖D
屏蔽的絕緣電阻測試程序如下:
將四個(gè)鍍銀電極A,B,C,D(見圖D
電極應(yīng)由適合的夾具連接。用于連接導(dǎo)體屏蔽的電極應(yīng)確保夾具與試樣絕緣屏蔽的外表面是絕緣的。
