The cable is manufactured according to GB9330 or IEC227 or JCS258C-1986, suitable to be used in the line system with AC. rated voltage of 450/750V or up to 0.6/1kV for controlling LV. power supply signal, protecting and measuring. It applies especially to the control lines of power station and substation up to 500kV. The interference from outside electromagnetic field can be suppressed by using the plastic insulated special shield control cable. 1.The permissible operating temperature of conductor shall not exceed 70oC when the cable is used for long period. The cable shall be installed at temperature not less than 0oC. The bending radius shall not be less than 12 times and 6 times of the cable overall diameter for armoured cable or copper tape shielded cable, non-armoured or copper wire shielded cable respectively.2.The shielding layer shall be earthed reliably on both ends, otherwise the reduction factor of shielding would be reduced.3.The effect of shielding would be increased with
PVC insulated PVC sheathed special shielded control cable
