Selection Guide
1. Select a Prysmian Kit Reference that corresponds to the cable diameter over insulation.
Example: 22kV single core aluminium 185sqmm cable with copper wire screen. Diameter over insulation is 28.6mm. Elbow type connector is required.
| Voltage | Diameter over Insulation (mm) | Approx Cable Size (sqmm) | Prysmian Part Number | |
| Min | Max | |||
| (11)12kV | 13.0 | 22.3 | 25-120 | MSCE(S)/EC-400-B-12-rA-25/120 |
| 16.1 | 26.3 | 95-240 | MSCE(S)/EC-400-B-12-rB-95/240 | |
| (15)17kV | 13.0 | 22.3 | 25-70 | MSCE(S)/EC-400-B-17-rA-25/70 |
| 16.1 | 26.3 | 35-120 | MSCE(S)/EC-400-B-17-rB-35/120 | |
| 20.2 | 30.8 | 95-240 | MSCE(S)/EC-400-B-17-rC-95/240 | |
| (22)24kV | 16.1 | 26.3 | 25-150 | MSCE(S)/EC-400-B-24-rB-25/150 |
| 16.1 | 26.3 | 70-185 | MSCE(S)/EC-400-B-24-rB-70/185 | |
| 20.1 | 30.8 | 95-240 | MSCE(S)/EC-400-B-24-rC-95/240 | |
| 22.7 | 33.0 | 95-240 | MSCE(S)/EC-400-B-24-rD-95/240 | |
| (33)36kV | 20.2 | 30.8 | 25-95 | MSCE(S)/EC-400-B-36-rC-25/95 |
| 22.7 | 33.1 | 35-120 | MSCE(S)/EC-400-B-36-rD-35/120 | |
| 25.6 | 35.3 | 70-240 | MSCE(S)/EC-400-B-36-rE-70/240 | |
2. Specify the voltage Um in kV. (12, 24 or 36kV)
3. Select earthing arrangement from the table below.
| Earthing Reference | Type of Metallic Screen on Cable |
| T1 | Polylam Cables |
| T2 | Copper Tape Screen |
| T3 | Copper Wire Screen |
4. Select suitable range taking lug.
➡ Prysmian Separable Connectors include tee, straight and elbow connectors including supporting range of MV HV equipment bushings for Interface A, B and C – complete range of heat shrink and Cold Shrink or Cold-Fit joints and terminations are available for 11kV/33kV up to 66kV cables. To support and retain the installation of medium/high voltage power cables refer to the range of Prysmian cable cleats suitable for short-circuit protection and retention of cables located onto cable containment.
