| Maximum carrier diameter after perforator firing, mm: | |
| in a liquid environment | 53 |
| in a gas environment | 57 |
| Section length, m | 1/2/3/4/5/6 |
| Maximum length of intervals perforated in one run, m: | Limited by the maximum lifting height of the suspension sheave (when deployed on wireline) or by the load capacity of the CT and plate used (when deployed on CT) |

| Phase orientation of charges, deg.4) | 60 |
|
1) The maximum allowable operating temperature and holding time of the loaded perforator are determined by the operational documentation for the EM (explosive materials) having the lowest allowable application temperature compared to the other EMs included in the explosive train of the perforator, as well as by the characteristics of the rubber products used. 2) The maximum allowable pressure may vary depending on the mechanical properties of the carrier tubes. 3) Mass of a running meter of a fully loaded section excluding the mass of reusable elements. 4) Phasing can be changed by special order. |
