Summary Elbow type PT connector be used as full insulation, fully shielded, fully sealed connection for JDZ12A-10R Transformer which providing operating power supply or measuring protection for electric operating mechanism. Applicable for 15kV XLPE cable cross-section of 35mm² ~ 50mm². Techncial characteristic 1, Ensure its reliability for the full insulation, fully sealed, fully shielded performance,Compare with others,its size is more compact. 2, The test point can be installed with a point of display or fault indicator, in order to display the device is charged and fault status. 3, The inner and outer shield design makes the electric field structure more optimized, the outer shield grounding, effectively keep the outer surface of the cable head zero Potential to ensure personal safety during maintenance operations. 4, The plug can be used between the rear of the cable and shrink tube shrink seal, in order to prevent moisture intrusion cable problems.
