Medium Voltage Cable Accessories Figure two offers a standard HF sign polarity diagram of the oil–oil bushing transformer, in the event the 220 kV C-phase cable terminal was the signal source. The posture of HFCT with the grounding wire with the phase A cable terminal to the 220 kV side must be saved unchanged every time (yellow ring).

Warmth shrink cable terminal joint kits are greatly employed within the terminals of 35KV and below cross-linked cables and oil-immersed cables.
If the abnormal sign originates from 1 period, enough time distinction of arrival (TDOA) positioning for the irregular period is completed. If there is not any variation during the three-stage signal polarity, the 3-phase signal polarity really should be compared with that in the grounding wire to find out whether it is from floor grid interference.
PMIC collection prefabricated inner cone GIS termination is suitable for link of extruded cable to forty.5kV CGIS switchgear or other electrical products. It is applicable for both of those of indoor and outside installations and offers a reputable reference to a servicing free and dry variety design. GIS Cable Termination
