摘要： An electrical penetrator assembly is shown, configured to feed electrical voltage and current through a wall separating a first volume and a second volume, which may have different pressure and/or may be filled with different fluids. The connector comprises a wall or partition having a through opening. An electrical conductor surrounded by a tubular insulator body passes the opening through the wall. A conductive or semi-conductive coating is arranged on the exterior of the insulator body, the coating surrounding the insulator body for a portion of its length, the coating in electrical contact with the wall, wherein the coated portion of the insulator body is shaped to displace the electric field around the conductor away from the wall and reduce the electric field strength around the insulator body by increasing the electric field strength inside the insulator body.

摘要： The present invention relates to a modularized pump. The pump has end lids 12, 13 with an inlet and an outlet for pumped fluid, and at least two pump modules 7 sandwiched between the end lids 12,13. Each pump module includes a casing 1 with an enclosed volume 20 and at least two pump stages 6. At least one coolant inlet 10 and outlet and a separate power connection 16 for connection to a VSD is included in each module. Each pump stage 6 includes an impeller 5 with a rotor 4, a stator 2 surrounding the rotor 4, provided to drive the rotor and a can 3 between the impeller 5 and the stator 2.

摘要： An electrical penetrator assembly comprising a penetrator housing (1), at least one conductor (2; 22) capable of conducting electrical power extending from a first end of the penetrator housing, an insulator body (8; 20; 30) surrounding the conductor, wherein the conductor passes through the insulator body from an axially facing opening (13) in a first end of the insulator body to a laterally facing opening (14; 23; 33) in the side of the insulator body, the laterally facing opening (14; 23; 33) located in a section PO of the insulator body which is sealed (S1; S2) towards the penetrator housing on each side of the lateral opening.
